Asynchronous motor with gearbox and without encoder (open loop)
Project: _________________________ Control cabinet serial Nr: ___________________
Nominal speed: ___________ m/s Roping ratio: 1:____ Compensation: YES NO
Contract load: _________ kg Inverter SW: ____________________
Nr. of stations: _______ Min. distance between stations __________ m
Motor Power: ____________ kW RPM: _____________
Current: __________ A Power factor: ___________ Voltage: ___________ V
Start up procedure
1. Check mains supply, control cabinet and wiring to ensure that there are no obvious problems, i.e. everything connected, correct wire and terminal colors… When using two speed motor, only windings for high speed must be used! Motor cable must be shielded. Shield must be connected to the ground on both sides with clamps, according to EMC guidelines. Switch power supply on. Done
2. Inverter parameters are preset before delivery, but some application dependent parameters (like motor and gearbox data, speed data) must be checked before running the lift. Find chapter “Parameters” on the next pages and set all the Ld and Lf parameters marked with *. The operator panel use is described on page 21 of this manual. Write password (11) to the parameter Lb.01 first. Adjust the parameters in ascending order so that partial pre-adjustments of the unit are initiated. If wrong parameters are displayed (CP, le, op, in, ru…), see explanation in the next chapter (Troubleshooting). Done
3. Inverter is now set up properly and you can check travel directions in maintenance mode. Change two phases on motor in case of wrong directions. Done
4. Verify proper operation of safety chain, emergency stops and pre-limit switches. Done
5. Switch to normal mode and make some floor runs. Adjust jerk, acceleration and deceleration values if necessary. See this manual page 40. Done
6. Carry out following checks/optimizations during some test rides:
Measure the motor speed during an inspection ride with a hand-held tacho. It should nearly be the same speed at „Empty-up“ and „Empty-down“. If not, change the motor rpm (Ld.02) in steps of 5…10 rpm to obtain nearly the same results. Load dependent stopping will be much better after this optimization.
The rolling back at releasing the brake or at stopping can be optimized by increasing LF.16 in steps of 0.5%. Done
Important note
When valid password is written to Lb.01, AG is displayed at power on. If “ENTER” key is pressed at that point, all parameters are reset to factory settings. Only “FUNC” key should be used when
AG is displayed.
To avoid parameter loss, write value 10 to Lb.01 when commissioning is finished!
ALFI Commissioning Open Loop page 8
Troubleshooting
Verify Ld and Lf parameters, especially motor parameters again!
Problem Solution
An error (E…) is displayed. See error messages explanation in this manual page 65. Some
messages are explained below too.
Parameter values can’t be
changed.
Write password (11) to Lb.01.
Contactors Q6 and Q6A are switched on but Q9 (brake) is
not.
Verify that all three phases are connected correctly from inverter to motor.
Check voltage on inverter input terminals. When Q6 and Q6A are
switched on, +24V relative to inverter terminal 23 must be on inverter terminals 16 and 14 or 15.
Check Li.03, it should show set speed. If it shows 0, check wiring of inverter terminals 10, 11 and 12.
Repeat setup procedure described above.
Vibrations during travel, car does not move at all or current
is too high.
Travel is not smooth.
Verify that lift is correctly balanced; guides and guide shoes must be clean and lubricated, check other mechanical problems too.
If there are vibrations in low speed only: decrease Lf.16 if Lf.17 is 0; decrease Lf.18 if Lf.17 is 1.
If vibrations occur during travel in small speed when coming nearer
to the station it helps increasing the small speed; set the parameter Lf.21 to 0,15 or 0,2. After this change, it is required to set magnets
and switches Stop in the stations again.
There is a jerk at start when
brake is opened.
Increase Lf.16 if Lf.17 is 0; increase Lf.18 if Lf.17 is 1.
If Lf.16 and Lf.18 values are too high, vibrations may occur in low
speed.
Try to change brake release time (Lf.40).
There is a jerk at stop when
brake is closed.
Increase Lf.41 on inverter and / or Stabilization time on controller
(E-type or D-type). Check Lf.42.
Lf.41 should be set so that brake is really closed in this time.
Easiest way to set Stabilization time correctly is by observing contactors Q6 and Q6A during stop sequence. If they are switched
off immediately with brake closing then Stabilization time is too short. Ideally, contactors should be switched off approx. 0.5 second
after brake is closed.
t_out or busy message is displayed occasionally on MRL
lift.
Communication cable between operator and inverter should be separated from other cables. Shielded cable with special interfaces
should be used.
E.Puch message is displayed Write code 440 to Lb.01, find parameter sy.03 and just confirm its value.
Find ud.01 after this and set it to 11. This will activate lift
parameters again.
E.OS message is displayed Check Lf.43 and set it to 1,1 x Lf.01.
Strange parameters (CP, le,
op, in, ru…) are displayed on operator; L… parameters are
not available.
Find ud.01 or CP.0 and set it to 11. This will activate lift
parameters.
Check operator type (label on the back side). It should be type
00F5060-200C.
ALFI Commissioning Open Loop page 9
Problem Solution
Strong noise from the motor
during travel.
Try to increase Lf.19.

Ld.13 auto Field weakening speed.
Ld.20 80 Not used.
Ld.22-24 --- Do not change!
Note
Ld.08 is a very important parameter. There are two possibilities for stator winding resistance determination:
a. The simplest way is measurement between terminals 5 and 6 in control cabinet. Check ohmmeter wires resistance after that (short circuit them) and subtract this value from initial measurement to get the result. If four wire connection is used, this correction is not needed. Measurement:_______ Ω Ohmmeter wire resistance:________ Ω
b. Inverter could make the measurement by itself too. The procedure is following:
Parameters Ld.01 to Ld.06 must be set correctly, then set Ld.07 to 1 and go to Ld.08.
Switch lift controller to maintenance mode. Be sure that all safety inputs and both pre-limit switch inputs are on. Press and hold maintenance up or down button. Q6 and Q6A must go on. If not, see lift controller manual, chapter Troubleshooting. Be careful - if something is wrong, car could move. Brake shouldn’t be opened during this procedure.
Press UP key on inverter operator ALFI once the Ld.08 value is displayed. At this moment measurement starts and it is completed in approx. 10 s, after which measured value displays and maintenance button can be released.
Ld.08:________ Ω Done

Write password (11) to the parameter Lb.01 first. Adjust the parameters in ascending order so that partial pre-adjustments of the unit are initiated. If wrong parameters are displayed (CP, le, op, in, ru…), see explanation in the next chapter (Troubleshooting). Done
3. Try to move the car up and down in maintenance mode. Observe current (Li.11), set speed (Li.03) and actual speed (Li.04). If everything is correct, go to the next step. If not, do the following:
If speeds and current are correct but direction is wrong, set parameter Lc.13 to 16.
If speeds (Li.03 and Li.04) have different pre-sign (one is minus and the other not), change encoder direction with setting parameter Lc.13 to 1. If travel direction is wrong after that, set Lc.13 to 17.
If there is something else, see troubleshooting in the next chapter. Done
4. Verify proper operation of safety chain, emergency stops and pre-limit switches. Done
5. Switch to normal mode and make some floor runs. Adjust jerk, acceleration and deceleration values if necessary. See this manual page 40. Done
6. Carry out following checks/optimizations during some test rides:
Optimization of the load transfer by increasing LF.13 in steps of 500, if the drive turns away too much on releasing the brake.
If motor rpm isn’t known or isn’t accurate it can cause problems. Switch to open loop mode (Lf.10=0) and follow open loop setup instructions. Carry out optimization with hand-held tacho as described there. Keep motor rpm information and switch back to closed loop (Lf.10=2). Done
ALFI Commissioning Closed Loop page 13
Starting of elevator with cantilever sling can be significantly improved with parameters Lf.52 and Lf.53. Typical value of Lf.52 is 4000 and 2 for Lf.53. Done

See this manual page 71 and adjust Lf.11 and Lf.12.
Encoder cable must be separated from power cables; shield must
be connected to ground at both sides. Try to increase Lc.17.
If speeds (Li.03 and Li.04) have different pre-sign (one is minus and
the other not), change encoder direction with setting parameter
Lc.13 to 1. If travel direction is wrong after that, set Lc.13 to 17.
There is a jerk at start when
brake is opened.
Try to change brake release time (Lf.40).
Try with Lf.13 = 0 and Lf.13= 10000. Fine tune this parameter in
steps of 500 after that if needed.
There is a jerk at stop when
brake is closed.
Increase Lf.41 on inverter and / or Stabilization time on controller
(E-type or D-type). Check Lf.42.

Check operator type (label on the back side). It should be type
00F5060-200C.
Modulation is started, current is running but motor doesn’t
move.
Check Lf.11 and Lf.12, they should be set to > 100.
Strong noise from the motor during travel or during
acceleration and deceleration only.
Decrease Lf.11 and Lf.12. If they are at preset values (1920 and 1250), try to set them to half (1000 and 600). If those values are
too low, motor will become ‘soft’ and will not follow the speed profile.
See this manual page 71 too.
If it doesn’t help, try to increase Lf.19 and / or Lc.17.
Lift doesn’t reach high speed
during ‘empty car down’ travel.
Try the following:
1. Reduce field weakening speed in Ld.13 to 2/3 of the synchronous speed.
2. Set cos phi in Ld.05 to 0,9.
3. Reduce motor nominal speed (Ld.02) in steps of 20rpm until the lift reaches set speed in 'empty-car-down'.
Check if Ld.12 is set to the maximum (maximum torque the inverter can provide is indicated in Ld.11).
E.hSd message (high speed
difference) is displayed.
- Check if encoder is fixed to the motor shaft.
- Adjust Lf.11 and Lf.12, see this manual page 71.
- Set Lf.46 to 0 if UPS evacuation is not used.
- Increase Ld.20 if this message appears during UPS evacuation.
Problems with automatic battery evacuation
When automatic battery evacuation is activated, the easier direction is determined in time of Lf.40, namely frequency inverter opens the
brake and waits in which direction cabin moves by itself. This can last a while, therefore it is important to increase Lf.40 even as much
as 0,70 s.

Start up procedure
1. Check mains supply, control cabinet and wiring to ensure that there are no obvious problems, i.e. everything connected, correct wire and terminal colors… Check motor wiring; terminals U, V, W from inverter must be connected via Q6, Q6A and terminals 5, 6, 7 to the motor terminals U, V, and W in the same sequence. Motor and encoder cables must be laid separately and shielded. Shields must be connected to the ground on both sides with clamps, according to EMC guidelines. Switch power supply on. Done
2. Inverter parameters are preset before delivery, but some application dependent parameters (like motor and speed data, system position) must be checked before running the lift. Find chapter “Parameters” on the next pages and set all the Ld, Lc and Lf parameters marked with *. The operator panel use is described on page 21 of this manual. Write password (11) to the parameter Lb.01 first. Adjust the parameters in ascending order so that partial pre-adjustments of the unit are initiated. If wrong parameters are displayed (CP, le, op, in, ru…), see explanation in the next chapter (Troubleshooting). Done
3. Try to move the car up and down in maintenance mode. If travel directions are wrong, set Lc.13 to 16. Done
4. Verify proper operation of safety chain, emergency stops and pre-limit switches. Done
5. Switch to normal mode and make some floor runs. Adjust jerk, acceleration and deceleration values if necessary. See this manual page 40. Done
6. Carry out following checks/optimizations during some test rides:
Optimization of the load transfer by increasing LF.13 in steps of 500, if the drive turns away too much on releasing the brake.
For fast lifts it may be necessary to use the torque precontrol, to ensure a perfect load transfer. Done
Starting of elevator with cantilever sling can be significantly improved with parameters Lf.52 and Lf.53. Typical value of Lf.52 is 4000 and 2 for Lf.53.
Done
Important note
When valid password is written to Lb.01, SG L is displayed at power on. If “ENTER” key is pressed at
that point, all parameters are reset to factory settings. Only “FUNC” key should be used when
SG L is displayed.
To avoid parameter loss, write value 10 to Lb.01 when commissioning is finished!
ALFI Commissioning Synchronous page 19
Troubleshooting
Verify Ld, Lc and Lf parameters, especially motor parameters again!
Problem Solution
An error (E…) is displayed. See error messages explanation in this manual page 65. Some
messages are explained below too.
Parameter values can’t be
changed.
Write password (11) to Lb.01.
Contactors Q6 and Q6A are switched on but Q9 (brake) is
not.
Verify that all three phases are connected correctly from inverter to motor.
Check voltage on inverter input terminals. When Q6 and Q6A are
switched on, +24V relative to inverter terminal 23 must be on inverter terminals 16 and 14 or 15.
Check Li.03, it should show set speed. If it shows 0, check wiring of inverter terminals 10, 11 and 12.
Repeat setup procedure described above.
Vibrations during travel, car does not move at all or current
is too high.
Travel is not smooth.
Verify that lift is correctly balanced; guides and guide shoes must be clean and lubricated, check other mechanical problems too.
See this manual page 71 and adjust Lf.11 and Lf.12.
Encoder cable must be separated from power cables; shield must
be connected to ground at both sides. Try to increase Lc.17.
There is a jerk at start when brake is opened.
Try to change brake release time (Lf.40).
Try with Lf.13 = 0 and Lf.13= 10000. Fine tune this parameter in
steps of 500 after that if needed.
There is a jerk at stop when brake is closed.
Increase Lf.41 on inverter and / or Stabilization time on controller (E-type or D-type). Check Lf.42.
Lf.41 should be set so that brake is really closed in this time.
Easiest way to set Stabilization time correctly is by observing
contactors Q6 and Q6A during stop sequence. If they are switched
off immediately with brake closing then Stabilization time is too short. Ideally, contactors should be switched off approx. 0.5 second
after brake is closed.
t_out or busy message is
displayed occasionally on MRL
lift.
Communication cable between operator and inverter should be
separated from other cables. Shielded cable with special interfaces
should be used.
E.Puch message is displayed Write code 440 to Lb.01, find parameter sy.03 and just confirm its
value.
Find ud.01 after this and set it to 11. This will activate lift parameters again.
E.OS message is displayed Check Lf.43 and set it to 1,1 x Lf.01.
Strange parameters (CP, le, op, in, ru…) are displayed on
operator; L… parameters are not available.
Find ud.01 or CP.0 and set it to 11. This will activate lift parameters.
Check operator type (label on the back side). It should be type 00F5060-200C.
Modulation is started, current
is running but motor doesn’t move.
Check Lf.11 and Lf.12, they should be set to > 100.
ALFI Commissioning Synchronous page 20
Problem Solution
Strong noise from the motor
during travel or during acceleration and deceleration
only.
Check if system position alignment was made, see parameter Lc.16
bellow.
Decrease Lf.11 and Lf.12. If they are at preset values (1920 and
1250), try to set them to half (1000 and 600). If those values are too low, motor will become ‘soft’ and will not follow the speed
profile.
See this manual page 71.
If it doesn’t help, try to increase Lf.19 and / or Lc.17.
E.hSd message (high speed difference) or E.EF (speed
deviation) is displayed.
- Check if encoder is fixed to the motor shaft.
- If motor is not loaded (without ropes), try to decrease Lf.13. If
this doesn’t help, increase Lf.51. If you have to increase LF.51 to
run the machine without load set it back after you put the load on.
- Increase Lf.13 if this error occurs at start with empty or fully loaded car.
- Adjust Lf.11 and Lf.12, see this manual page 71.
- Set Lf.46 to 0 if UPS evacuation is not used.
- Increase Ld.20 if this message appears during UPS evacuation.
E.EnC message (error encoder cable) is displayed.
Check encoder connection and encoder cable.
Encoder cable must be separated from power cables; shield must
be connected to ground at both sides.
E.EnC1 message (error encoder 1) is displayed.
Check motor wiring; terminals U, V, W from inverter must be connected via Q6, Q6A and terminals 5, 6, 7 to the motor terminals
U, V, and W in the same sequence.
Change encoder tracks by setting Lc.13 to 1.
Problems with automatic
battery evacuation
When automatic battery evacuation is activated, the easier direction
is determined in time of Lf.40 »Brake release time«, namely frequency inverter opens the brake and waits in which direction
cabin moves by itself. This can last a while, therefore it is important
to increase Lf.40 even as much as 0,70 s.

Note 1:
The motor windings inductance and resistance must be known. They could be measured and set as
described in this manual page 28 or can be measured with Ld.14 as follows:
Parameters Ld.02 to Ld.06 and Ld.10 must be set correctly, except Ld.03. Set Ld.03 to a half of nominal current to reduce the noise during measurement. Choose Ld.14, set it to 1 (start) and press Enter key.
Switch lift controller to maintenance mode. Be sure that all safety inputs and both pre-limit switch inputs are on. Press and hold maintenance up or down button. Q6 and Q6A must go on. If not, see lift controller manual, chapter Troubleshooting. Be careful - if something is wrong, car could move. Brake shouldn’t be opened during this procedure.
Wait about two minutes until Ld.14 shows 3 (ready); release maintenance up or down now.
Set Ld.03 back to nominal motor current.
Ld.08:________ Ω Ld.09:________ mH Done
Note 2:
Encoder to rotor position (Lc.16) must be known for synchronous motors. The alignment could be carried out with parameter Lc.15. All Ld and other Lc parameters must be set before. Ropes must
be removed form the sheave or car must be in the middle of the shaft and loaded so that system is balanced. In both cases it should be possible to rotate the sheave in both directions with
no big effort when brake is opened. The alignment procedure is following:
Choose Lc.15, set it to 1 (start) and press Enter key.
Switch lift controller to maintenance mode. Be sure that all safety inputs and both pre-limit switch inputs are on. Press and hold maintenance up or down button. Q6 and Q6A must go on; Q9 must be switched on manually. If Q6 and Q6A are not switched on, see lift controller manual, chapter Troubleshooting.
Sheave should rotate a little during this procedure.
Wait about two minutes until Lc.15 shows 3 (ready); release maintenance up or down now.
Lc.16:__________ Done
ALFI Commissioning Synchronous page 22
If it is not possible to balance the system or friction is too high, you can do the following:
Try to move the car on maintenance and increase Lc.16 in 10000 steps until it will go in both directions.
Move the car in maintenance mode and observe motor current (Li.11). Find the minimum value by changing Lc.16 in 1000 steps.
Note 3:
Parameter Lc.18 offers an alternative possibility to determine rotor position, that is its poles and therefore function Lc.15 is not needed anymore. Procedure is as follows:
First we set all parameters according to the manual, including motor torque resistance and
inductance. Lc.18 has to be set to 1 and tested with a test drive which sets Lc.16 to an actual value.
Should the installed encoder be absolute (ENDAT-SinCos or SSI-SinCos), several test drives need
to be done in order to observe value Lc.16. If motor functions as normal and value Lc.16 doesn’t change for more than 2500, then procedure is finished, setting Lc.18 to 0.
In the opposite case (motor doesn’t function or value Lc.16 oscillates for more than 2500) Lc.18
has to be set to 0, determining the rotor position according to the instructions for function Lc.15.
Should the encoder be incremental or SinCos (doesn’t have an absolute position), Lc.18 can’t be
set to 0.

1.3 Safety and Operating Instructions
Safety and Operating Instructions for drive converters(in conformity with the Low-Voltage Directive 2006/95/EG)
1. General
In operation, drive converters, depending on their de-
gree of protection, may have live, uninsulated, and
possibly also moving or rotating parts, as well as hot
surfaces.
In case of inadmissible removal of the required covers,
of improper use, wrong installation or maloperation,
there is the danger of serious personal injury and da-
mage to property.
For further information, see documentation.
All operations serving transport, installation and com-
missioning as well as maintenance are to be carried
out by skilled technical personnel (Observe IEC 364
or CENELEC HD 384 or DIN VDE 0100 and IEC 664
or DIN/VDE 0110 and national accident prevention
rules!).
For the purposes of these basic safety instructions,
„skilled technical personnel“ means persons who are
familiar with the installation, mounting, commissioning
and operation of the product and have the qualifica-
tions needed for the performance of their functions.
2. Intended use
Drive converters are components designed for inclusi-
on in electrical installations or machinery.
In case of installation in machinery, commissioning of
the drive converter (i.e. the starting of normal operati-
on) is prohibited until the machinery has been proved
to conform to the provisions of the directive 2006/42/
EC (Machinery Safety Directive - MSD). Account is to
be taken of EN 60204.
Commissioning (i.e. the starting of normal operation)
is admissible only where conformity with the EMC di-
rective (2004/108/EC) has been established.
The drive converters meet the requirements of the
Low-Voltage directive 2006/95/EC. They are subject
to the harmonized standards of the series EN 50178/
VDE 0160.
The technical data as well as information concerning
the supply conditions shall be taken from the rating
plate and from the documentation and shall be strictly
observed.
3. Transport, storage
The instructions for transport, storage and proper use
shall be complied with.
The climatic conditions shall be in conformity with EN
50178.
4 Installation
The installation and cooling of the appliances shall be
in accordance with the specifications in the pertinent
documentation.
The drive converters shall be protected against exces-
sive strains. In particular, no components must be bent
or isolating distances altered in the course of trans-
portation or handling. No contact shall be made with
ponents which are liable to damage through improper
use. Electric components must not be mechanically
damaged or destroyed (potential health risks).
5. Electrical connection
When working on live drive converters, the applicable
national accident prevention rules (e.g. VBG 4) must
be complied with.
The electrical installation shall be carried out in accor-
dance with the relevant requirements (e.g. cross-sec-
tional areas of conductors, fusing, PE connection). For
further information, see documentation. (Instruction
manual part 1)
Instructions for the installation in accordance with
EMC requirements, like screening, earthing, location
of filters and wiring, are contained in the drive con-
verter documentation. They must always be complied
with, also for drive converters bearing a CE marking.
Observance of the limit values required by EMC law is
the responsibility of the manufacturer of the installation
or machine.
A high frequency filter and a THD filter are additi-
onally required in order to meet the european lift
standard EN12015.
6. Operation
Installations which include drive converters shall be
equipped with additional control and protective de-
vices in accordance with the relevant applicable safety
requirements, e.g. act respecting technical equipment,
accident prevention rules etc.. Changes to the drive
converters by means of the operating software are ad-
missible.
After disconnection of the drive converter from the vol-
tage supply, live appliance parts and power terminals
must not be touched immediately because of possibly
energized capacitors. In this respect, the correspondi-
ng signs and markings on the drive converter must be
respected.
During operation, all covers and doors shall be kept
closed.
7. Maintenance and servicing
The manufacturer’s documentation shall be followed.

t1: The bit sample for the setpoint values and the direction of travel is set. Immediately after that the inverter
sets the output for the main contactors.
t2: The control release (Start) is set by a relay parallel to the main contactor control. Thereupon the output
phase check is executed.
t3: Upon successful output phase check the brake output is set. Thereupon the brake opening time runs out.
Then the motor starts to turn.
t4: The rated speed is reset and switched over to leveling speed.
t5: The leveling speed is reset and the stopping is initiated.
t6: On reaching the speed 0 rpm the brake output is reset. Afterwards the brake engage time runs off.
t7: The output for the main contactor is reset and thus also the control release and the direction of travel.
Generally the inverter switches the main contactors only in currentless condition.

2.5.4 Connection F5-Lift for UPS operation
1) We recommend the use of chokes to avoid current peaks. Without chokes the UPS may be bigger or go to the
limit.2) Alternatively a single-phase transformer 230 V AC can be used at 380 V AC.
Between disconnecting the mains and connecting the UPS to the inverter a certain time must run out to avoid a
short circuit. The same is necessary for switching back to the mains.
F5-A-Lift offers the possibility to select a digital input with the function „UPS-operation“. With this the undervoltage
threshold will be decreased to 200 VDC.
It is also possible to execute an evacuation with an undersized UPS. In that case it is possible to evacuate
people to that floor where the load pulls the cabin. For this a digital output with condition „9: simple direction of
rotation identification for UPS“ is programmed (see Lb.14…17).

t1 The travel direction and the set speeds VU and VL must be set.
t2 After a debounce timer run out the main contactors are controlled (powerless switching) . Via the main
contactors the control release X2A.16 is set and the inverter checks in all phases whether the current can
flow to the motor.
t3 When the motor phase check succeeds the output for the the brakes will be set and the brake release time
runs out.
t4 After the brake release time has run out the inverter starts turning the motor.The internal undervoltage level
is reduced to 200 VDC.
t5 When the car reaches the deceleration switch the setspeed inputs must be reset.
t6 When the motor has decelerated to zero speed the brake out will be reset. Afterwards the brake closing
time runs out.
t7 The main contactor output is reset after elapsed brake closing time. The control release is also switched
off with the main contactors and the direction of rotation can be reset.
For undersized UPS the inverter can recognise the „easy direction“. That means the travel direction will be in that
direction where the load is pulling (see also Ld.24). Therefore both direction inputs must be set together with the
set speed inputs.
