Chapter B - TECHNICAL DATA
Introduction
Figure 2-1 represents the block diagram of the inverter. The
inverter mechanically consists of two units, the Power Unit and the
Control Unit.
The three-phase AC line inductor (1) at the mains together with
the DC bus capacitor (2) form an LC-filter, which, together with
the diode bridge (4) produce the DC-voltage supply to the IGBT
Inverter Bridge (3) block. The AC line inductor also functions as a
filter against High Frequency disturbances from the mains as well
as against those caused by the IGBT inverter to the mains. It
improves the form factor of the DC bus input to the IGBT inverter
section. The entire power drawn by the inverter from the mains is
active power. The IGBT Inverter Bridge produces a symmetrical,
3-phase PWM AC-voltage to the motor.
The Motor and Application Control Block is microprocessor based.
The microprocessor controls the motor based on the information it
receives from internal sensors, parameter settings, control I/O and
control keypad. The motor and application control block controls
the motor control ASIC which, in turn, calculates the IGBT
switching patterns. Gate driver circuitry amplifies these signals
for driving the IGBT inverter bridge.

1) Before installation, check that none of the components of the
inverter is live.
2) If the inverter is installed outside a switchgear, enclosure
or electrical room, it must be equipped with a protective cover as
provided by the regulations for IP21 protection class. For
installations in a switchgear, enclosure or electrical room, the
cable protection plate is normally not necessary.
3) Route the motor cables clear of other cables: • Avoid placing
the motor cables in long parallel lines close to other cables • If
the motor cables run in parallel with other cables, note the
minimum distances
between the motor cables and other cables given in table below.
• The given distances also apply between the motor cables and
signal cables of other
systems. • The maximum length of the motor cables is 990 ft. on
all units. • The motor cables should cross other cables at an angle
of 90 degrees. 4) If cable insulation checks are needed, see
Chapter D.
5) Connect the cables: • Strip the motor and mains cables as
shown in Table 3-2 and Figure 3-2. • Remove the screws of the cable
protection plate. • Make holes into and pass the cables through the
rubber grommets on the bottom of
the power unit. • Connect the mains, motor and control cables
into their respective terminals. • For Information on cable
installation according to UL regulations see Chapter D • Make sure
that the control cable wires do not come in contact with the
electronic
components of the unit. • If an external brake resistor is used,
connect its cable to the appropriate terminal. • Check the
connection of the ground cable to the motor and the inverter
terminals
marked with ground symbol. • If shielded power cables are used,
connect the separate shield of the power cable
to the ground terminals of the motor and enclosure ground
terminal. • Attach the cable protection plate with the screws. •

Control unit
The control unit of the inverter consists roughly of the control
board and additional boards (see Figure 4-7a and Figure 4-7b)
connected to the five slot connectors (A to E) of the control
board. The control board is connected to the power unit through a
D-connector (1).
Figure D-7a Figure D-7b
Usually, when the inverter is delivered from the factory, the
control unit includes at least the standard compilation of two
basic boards (I/O board and relay board) which are normally
installed in slots A, B, and D. On the next pages you will find the
arrangement of the control I/ O and the relay terminals of the two
basic boards, the general wiring diagram and the control signal
descriptions. The I/O boards mounted at the factory are indicated

1 Description Functional description
See circuit diagrams for following descriptions of
operation.
Operation when power is switched on
− Limit switches S11, S12, S21 and S22 are assumed to be closed,
as well as the emergency stop button ES.
− The control voltage is supplied to A1 control inputs (external
42V…230V control voltage). The main voltage is connected to
inverter power supply and inverter wakes up. If the control voltage
is connected to RDY-signal and the fault circuit is OK, inverter is
ready to operate in about 1-2 seconds.
− If either one of the direction signals S1 or S2 is on, the
display shows F6 and running can begin only after the direction
signals have been off for a while.
Normal operation – For the description of the speed reference
setting see chapter 1.6
"Control methods". – Running starts when switch S1 (S2) closes.
Closing the contact ROB2
on A1 energizes K7, which opens the brake (in models 055F-132F
the brake can be controlled also by K71). XT Drive accelerate
according to the acceleration ramp setting to the selected
speed.
– When the switch S1 (S2) opens, XT Drive stop according to the
deceleration ramp setting and the brake closes.
– R1 dissipate the regenerated energy during deceleration and
lowering periods. The power supply to R1 is controlled by A1. If
the braking resistor fan(s) are included in external resistor unit,
they start to operate when power is supplied to the braking
resistors. The cooling continues about 4-5 minutes after electrical
braking to ensure that the temperature of the resistors drops below
150°C (302°F).
Other features – Slowdown limit switches S11 and S21 provide
position dependent
frequency limiting. – Any reason, which opens the contact RDY,
stops the operation of
inverter A1. – In case of overload, motor overheating etc. the
hoisting can be
disabled by cutting the direction signal in terminal X1:8. –
Thermistor relay function, which can be used when needed. – When
the stop limit switch S12 or S22 opens, K7 (K71 in models
055F-132F) de-energizes and the mechanical brake stops the
motion. – Independent speed supervision unit, SSU. – The speed
measurement and supervision can be done either with
encoder, bearing encoder or proximity switch. The measured
signals are square wave pulses. The frequency of the pulses is
proportional to the speed of the motor and if the frequency is too
high, overspeed is detected. If there are no pulses a stall
situation is detected. If the actual speed differs too much from
the supply frequency of the motor, the speed difference supervision
stops the motion.
– Proximity switch buffer amplifier amplifies the sensor pulses
and filters out disturbances. The amplifier is located close to the
sensor.
– The extended speed range ESR can be used, if the signal FWE
(field weakening enabled) is on. Then it is possible to run up to
twice the nominal speed depending on the application.

Control methods There are four different control methods
(command modes) available. All of them are available without any
changes in the hardware or software. Any single XT Drive can be
controlled either by a pushbutton controller in EP-mode, by a
joystick type controller with a potentiometer located in the cabin
in PO-mode or by a process computer in AU-mode. The only external
device needed is a switch to select the desired control method. EP
Electronic motor potentiometer function.
− Stepless control using a 2-step pushbutton controller. − EP3
stepless control using a 3-step controller.
PO Potentiometer control using a joystick type controller. −
Requires a single 15V power supply (included in XT Drive). − Any
additional amplifier is not needed.
AU Automation control − For any control device with an output in
the range of 0-10V. − E.g. radio-controls, process computers.
MS Multistep control (2-4 steps as standard). − Requires
programmable digital inputs for speed reference steps
(included in XT Drive).
Command mode selection
The command mode (EP, PO or AU) is selected by the switches CMS
and AP. Normally the selection can be done only when the motion is
stopped (not when running), but in special applications changing
the mode is allowed during run by changing parameter values.
PO- and AU-modes PO- and AU-modes select either of the analog
inputs for speed reference. Both analog inputs can be adjusted
similar from 0V to 10V (radio or PLC-reference) or from 10V to 6.7V
(potentiometer). As default, Ain1 is used in PO-mode and Ain2 is
used in AU-mode.

DIA3 AP not used AP not used AP not used AP = 0 AP = 1 DIA4 CMS
not used CMS = 0 CMS = 1 CMS = 1 CMS = 1
EP-mode EP-mode selects the AP-button for speed reference. EP
step 1 is command for minimum speed or hold speed. EP step 2 is the
acceleration command.
EP step 1 EP step 2 EP step 1 EP step 2
DIA3 AP = 0 AP = 1 AP = 0 AP = 1 DIA4 CMS not used CMS not used
CMS = 0 CMS = 0
Synchronization If required, two or more XT Drives can be run in
precise synchronization. A separate synchronization controller is
needed for this. The same speed reference (in EP- or PO-mode) is
connected to every XT Drive and the correction signal for
synchronization is connected to all XT Drive to input AIN2+. The
speed reference signal of each XT Drive can also be modified
separately by a PLC. Synchronization is activated by parameter
selection.

Description of the control methods EP-control requires two
2-step pushbuttons, one for each direction. The operation is as
follows: − the rest position means standstill (0-position) − during
run the rest position means deceleration − step one (switch S1 or
S2) means hold speed − when starting, step one means acceleration
up to
the minimum speed − step two (switch AP) means acceleration (up
to
the maximum speed if desired) − at the maximum speed step two
means hold

EP3-mode PO-control requires a controller with potentiometer.
The operation is as follows: − when the controller is at the rest

− run commands are controlled separately by closing the
direction switches (S1 and S2)
− when the operator turns the controller to any direction, the
speed increases
− the same turning angle of the controller causes a smaller
change in speed, the closer the speed is to the minimum speed
AU-control requires an analog reference from radio or PLC. The
operation is as follows: − the speed linearly follows the input
signal. 0V
means zero speed and the higher the voltage, the higher the
speed

Mechanical brake control The brake is controlled so that during
starting the motor first generates torque and after that the brake
is opened. The same applies for stopping; while the brake is being
closed, the motor still generates torque. During a direction
change, the brake is kept open all the time. XT Drive decelerates
the motor to a stop according to the set deceleration time when the
run command is switched off, so the brake is used only as a holding
brake. This way brake wear is minimized. Only if a failure occurs
or the emergency stop button is pushed, the brake closes
immediately stopping the motor and the load. The motors of
CXT-hoists and SM-trolleys have an electromechanical disk brake.
The disk brake is opened and kept open during run by DC-voltage.
When there is no voltage present the brake is closed and also kept
closed by spring force. 2-phase AC - 002-045F
XT Scalar models 002F-045F include an AC-supply from two phases
for the disk brake control. XT Drive controls this line and it is
protected by an adjustable circuit breaker (max.4.0A). A rectifier
included in the motor rectifies the AC-voltage to DC-voltage brake
coils.
REC12 - 002-011F
XT Vector models 002F-011F have a built-in REC12 brake control
unit, which is a line voltage half-wave rectifier (max.1.25Adc).
The half-wave type rectifier reduces losses and is enough to open
the brake. There is a contactor to switch the line voltage on and
off. An external control unit is needed to control other brake
types.
ESD141 - 015-110F
XT Vector models 015F-132F have a built-in ESD141 brake control
unit, which is a line voltage full/half-wave rectifier
(max.1.25Adc). Full-wave rectification is used to open the brake
quickly. Then, the rectifier changes to a half-wave type, which
reduces losses, but is enough to keep the brake open. There is a
contactor to switch the line voltage on and off. The same contactor
also disconnects the DC-voltage directly from the brake coil, which
guarantees that the brake closes fast. An external control unit is
needed to control other brake types.
3-phase AC - 055-110F - 055-110F
XT Drive models 055F-132F include a 3-phase AC-supply for the
brake control. XT Drive controls this line and it is protected by
an adjustable circuit breaker (max.4.0A). When a shoe brake is
used, brake closing is speeded up by capacitors. They are connected
in parallel with the brake via the brake contactor NC-contacts. The
connection is partially ready in XT Drive. Only the capacitors must
be added outside XT Drive. This connection can also be used to
control 2-phase disk brakes or a separate KA372B brake control
unit.

2 START-UP PROCEDURE If any problems or malfunctions occur
during the start-up, refer to Chapter “Troubleshooting”, to find
out the reason. All problems must be solved before continuing.
− Do not connect any voltage to the output terminals (U, V, W).
Otherwise, the inverter will be
damaged. − The overload protection protects both the supply and
the motor cables. The fuses of the supply
provide short circuit protection.
Visual checks – Record all checks and results. – Check condition
of the cubicles. – Check that XT Drive serial number is the same as
in the delivery documents. − Check the switch settings on SSU.
− If necessary, open the control box cover and adjust the SSU
settings. − Check the cabling to the motor, brake, thermistors and
speed sensor. − Check the motor type. − Check the wire terminations
in the motor connection box
− Check connections for motor, thermistors, heaters, brake wear
and speed sensor circuits. − Disconnect motor (U, V, W) and brake
cables to prevent damage of the inverter. Measure the
isolation resistance of the brake coil and the motor windings
(each phase to ground). − Re-connect motor and brake cables. −
Check braking resistor(s). − Terminals X1:21-27 and X1:51-57 are
for electronics level signals.
− Normally only shielded wires are connected to these terminals.
Check that no control or line voltage level wires are connected
there.
Checks before the first test run
Warning! High voltages inside the device.
− Check the power supply voltage (nominal voltage +/- 10%). –
Make sure that run commands are off (pushbuttons / controller
(master switch) at zero position). − Turn on the power from the
main switch and the control voltage switch. – Within about 1 second
the keypad should display "AC on", and then in about 1 second
the
display changes to the motor output frequency "0.00" and the
green READY status indicator turns on. – In a fault situation, the
red FAULT status indicator blinks and the display shows a fault
code
instead of frequency. − Check that the green RUN status
indicator is off. − Check that the external connections and
programming of digital inputs are according to the
application. − The parameters are properly set after factory
tests and no adjustments are needed except for
the parameters that depend on the application and the motor.
Write down in the parameter list all the values that have been
changed.
Warning! High voltages inside the device. Wait for at least five
minutes after the supply voltage has been switched off before doing
any service actions. The display in the operating condition (lights
on) indicates a dangerous voltage on the DC-bus. When display turns
off, the DC-bus voltage is approximately 100V. Note also that there
is always a dangerous voltage in the braking resistor when the
DC-bus is charged.

Test run without load − Make sure that movement will not cause
any danger to the environment or to the crane itself.
Avoid running close to the limit areas. − Check the limit
switches manually if possible. − Check the run commands on the
keypad display and correct the motor rotating direction. The
arrow rotates clockwise if S1 (fwd/up) is applied, and
counter-clockwise if S2 (rev/down) is applied.
− Check the function of the speed sensor. − Check the function
of the speed supervision circuit. − Run forward (upwards) at
minimum speed for 5 to 10 seconds. Accelerate to full speed. Run 5
to
10 seconds. Stop. Repeat the same in the reverse (down)
direction. Check the frequency display to make sure that the
frequency changes through the whole operational frequency range
from the minimum to the nominal speed.
− Check the motor operation (acceleration, deceleration and
braking): accelerate to full speed forward (up), change to full
speed reverse (down) and full speed forward (up) again and
stop.
− Check the limit switch functions: run forward (up) slowly and
check the slowdown and the stop limit switch operations. Re-check
using full speed. Repeat the same check for the reverse (down)
direction.
− If the optional ESR is used, check the maximum frequency.
Test run with load − Note, three loads are required:
− Nominal load (100%) for normal operation. − Limited load for
ESR (optional). − An adequate extra load for dynamic overload
testing and to test the ESR load limit.
− See the maintenance instruction HU1.03.0004 “Erection,
Installation and Testing of EOT cranes” for the details of the load
tests.
– Make sure that movement will not cause any danger to the
environment or to the crane itself. − If the optional extended
speed range (ESR) is used, check that the load limit is correctly
set and
hoisting with bigger loads is prevented. – Run in both
directions at minimum and maximum speeds. − If the fan tube
resistor unit is included, check that the fan(s) starts to blow
when running down
with nominal load and continues to blow for about 4-5 minutes
after stopping.
After the test run – Record all the parameter value changes in
the parameter list. – Make sure all remarks and setting values are
recorded.

FAULT CODES If any of the following failures are found, the
inverter displays the fault code and closes the mechanical brake
causing the movement to stop. If several faults occur one after
another, the latest one is displayed, the others are stored to
fault history page. When inverter fault supervision trips, the
FAULT indicator turns on and the blinking fault code “F xx“ (xx =
fault number) appears on the display. XT Drive includes an
automatic fault reset operation; the fault code stays on the
display until the fault is removed and the controller released back
to 0-position. Some of the fault codes require to switch the power
off before run is possible. The faults are stored to the fault
history, from there they can be seen if necessary. The fault
