1.2 CautionsNote

1. Check the Insulation of the Motor

If parameter identification is required, please pay attention that the rotating motor may injure people, otherwise ac cident may occur! Do not change the factory settings, otherwise the inver ter may be damaged!

When the motor is used for the first time, or reused after storing for a long time, or in regular checkup, the user mus t check the insulation of the motor to prevent the poor insulation of the windings of motor from damaging the inverter. The motor connection must be divided from the inverter during the insulation che ck. It is recommended to use a 500V Mega-Ohm-Meter to check and the insulation resistance shall not be less than 5M. 2. Thermal P rotection of Motor If the rated capacity of the motor selected is not matching that of the inverter, espec ially when the rated power of the inverter is bigger than that of the motor, make sure to adjust the parameters for motor protection inside the inverter or to install a thermal relay to the motor to guarantee the protection to the motor. 3. Running a t Frequency Above Rated Frequency The output frequency of this inverter is 0~600Hz. Please consider the capability of the mechanical devices whe n the customer needs the inverter to run at the frequency higher than 50Hz . 4. Motor He at and Noise Since the output voltage of the inverter is in PWM wave with some harmonics, the temperature may rise, the noise and vibration may increase compared with the inverter running at main frequency. 5. Pressure-sensitive Device or Capacitor at the Output Side of the Inverter Because the inverter outputs PWM wave, the capacitor used for improving power factor and pressuresensitive res istor used for lightening-proof shouldn't be installed at the output side of the inverter, otherwise the inverter may have transient over-current and may be damaged. 6. Switches Used at the Input a nd Output terminal of the Inverter If the contactor is required to be installed betw een the inverter and the power supply, it is prohibited to start or stop the inverter with the contactor. If the user has to use the contactor to start a nd stop the inverte r, the interval between the start and stop shall be less than one hour. Frequent charging and discharging ma y reduce the life of the capacitor. If the switches like contactors are connected between the output terminal and the motor, make sure to start and stop the inverter when the inverter has no output, otherwise the modules in the inverter may be damaged. 7. Usage Outside the Range of Rated Voltage The DZB series inverter shall not be used out of the specified range of operation voltage, otherwise the internal components of the inverter may be damaged. If needed, please use corresponding voltage regulation device to change the voltage. 8. 3-phase Input Modified Into 2-phase Input The modification of DZB series inverter from 3-phase input to 2-phase input is not allowed, or fault may occur. 9. Lightning Strike Protection There are lightning protection devices inside the inverter, But the user should install other lightning protection device at the front end of the inverter if lightning strike occurs frequently. 10. Altitude and Deration When the altitude is higher than 1000m, the cooling effect of inverter is deteriorated because of the rarefaction of air, the deration must be used and please consult our company for detailed technical support.

6. Running


Do not approach the equipment when restart function is enabled, otherwise there w ill be danger of injury. Do not touch the fan and the discharging resistor to check the temperature, otherwise burning may occur! Non-prof essional person shall not measure the signal of a running inverter, otherwise there will be danger of injury or damaging the inverter!


Do not let objects fall in a running inverter, otherwise the inverte r may be damaged! Do not start and stop the inverter by on/off of the contactor, othe rwise the inverter may be damaged!

7. Maintenance


Please do not repair or maintain the inverter with power on, otherwise there will be danger of electric shock! Please repair or maintain the inverter after confirming the charge LED turns off, otherwise there may be human injury caused by the residual voltage of the capacitor! Only qualified electrical engineer can repair or maintain the inverter, otherwise there will be danger of human injury or damaging the equipment.

11. Special Usages The user can consult our company if he wants to use another method instead of the recommended connecting method provided in the manual, such as shared DC bus. 12. Cautions for Scrap of Inverter The electrolytic capacitors in the main circuits and PCB may explode when they are burned a nd poisonous gas may be generated when the plastic parts are burned. Please dispose the inverter as industrial rubbish. 13. About Applicable M otor 1) The standard motor used is the 4-pole squirrel cage asynchronous induction motor. If other kind of motor is used, please be sure to select the applicable inverter according to the rated current of the motor, and please consult us if the user wants the inverter to drive the permanent magnetic synchronized motor. 2) The cooling fan of non-variable frequency motor is connected to the rotor in the same bearing, so the cooling effect is weakened if the speed is low, therefore use the variable-fr equency motor or install a cooling fan in the overheat condition the motor. 3) The inverter has already been configured with the standard parameters for applicable motor, please be sure to modify the default values or perform the motor parameter identification according to the actual conditions, otherwise the oper ation effect or prot ection performance may be reduced. 4) Short-circuit in the cable or motor may cause the inve rter alarm or even damage the inverte r. Therefore, please conduct the insulation short-circuit test to the cable and the motor installed for the first time. The shor t-circuit test shall also be carried out in routine maintenance. Pay attention that the inverter shall be separated from the unit during such test. The purpose of this chapter is to provide specific, yet simple information to unpack , install the AC drive.

2) Reducing the disturbance to the inverter from other equipment

Note: Pay attention to the polarity of the diode as shown in the figure 3-8. Otherwise if the digital output terminal has output, the DC24V power supply will be damaged.

The re lay, contactor or electronic -magnetic braking device will disturb t he invert er. Take the following act ions to solve this issue: A) Install surge suppressing devices to the disturbing de vice B) Install filter to the input of t he inverter C) Inverter's c ontrol cables shall be shie lded and the shielding layer shall be grounded 3) Method to reduce the disturbance from the inverter to the equipment Two kinds of noises, one is the radiation from the inverte r itself, and another is the radiation from the




cable between the inverter and the motor. These two kinds of radiations induce the cables of the equipment and make the equipment work abnormally. Following method can be used: A) If t he measuring meters, radio equipment and sensors and their signal cables are install ed in a cabinet together with t he drive , these equipment cables will be easily dist urbed. Take the actions below to solve the problem: The equipment and the signal cables should be as far away from the inverter as possible; Signal cables and power cables shall not be routed in parallel or bound togethe r;



The signal and power cables should be shielded; Install r adio noise filter and linea r noise filter at the input and output sides of the inverter B) If the exter nal equipment shares a sa me AC supply wi th the inverter, and the above cannot eliminate

Fig. 3 -8 Digital Input Terminal of DZB Series Inverter6. EMC Issues 6 . 1 Influence of Harmonics 1) The high frequency harmonics of mains supply will influence the rectifying circuit of the inverter. The harmonics will heat the rectifying circuit and even damage the circuit. So, it is recommended to install the filtering device in the envir onment where the power quality is poor. 2) Since the inverte r output has high frequency harmonics, the output cannot be installed with capacitor or surge suppressing devices because the capacitor and surge suppressing device may resonate the circuit and damage the equipment. 6.2 EMI 1) Two kinds of EMI, one is the EMI a round the inverter and disturbs the inverter. This kind of EMI is weak, besides the inverter has been designed with strong immunity. Another is the EMI from the inverter that may influence the equipment around the inverter. The inverter itself is a disturba nce source because it outputs PWM wave through high carrier frequency, so solving the EMI issue is mainly to reduce the EMI of inverter. Methods: A) Inverter and other equipment shall be well grounded and the grounding resistance shall be less than 5ohm. B) Inverter's power cables shall be vertical instead of parallel with the control cables. C) For the application with strong disturbance, the powe r cables from the motor to the inverter shall be shielded and the shielding layer shall be grounded. D) The cables of disturbed equipment shall be twisted shielded cables and the shielding layer shall be grounded.

the disturbance, then t he user should install a linear filter or a radio noise filter. C) Ground the external equipment and e liminate the disturbance of the leakage current from the inverter's grounding ca ble. 6.3 Le akage current The inverter has two kinds of leakage current, one is the grounding leakage current and another is the leakage current between the lines: 1) Grounding leakage current: The distributed capaci tance exists betw een the cables and the ground, and the bigger the c apacitance and the bigger the leakage current, so the motor cables should be as short as possible. Besi des, the bigge r the carrier frequency is, the bigger the leakage current is, so the user can al so reduc e the carrier wave frequenc y, but the motor noise may increase. Insta lling rea ctor can also reduce the leakage current. The leakage current is increased with the increase of the circuit current, so the lea kage current is big if the motor power is big. 2) Lea kage current bet ween lines: The distributed capaci tance exists in the inverter output cable s, and resonance may occur if high frequency harmonics e xist in the current, thus the leakage current occurs, which may result in the wrong action of relay. The method to solve this issue is to reduce the carrier fre quency or install the output reactor. It is recommended to use inverter protection func tion instead of a thermal relay to protect the motor before using the inverter.

Note: When operating 3-level menu, pressing PRG or DATA can return to second level menu. The difference is: pressing DATA will save the parameters and return to second le vel menu and then shift to the next function c ode, while pressing PRG will return to second level menu without saving the parameters. Example: Change the setting of F1.02 from 10.00Hz to 15.00Hz. (Bold means flash bit.)

4.4 Password Setting DZB300 inverter provides password protection for users. When F3.00 is not zero, that is the user password, and the password protection function is valid once exiting the function code editing status. If the user presses PRG again, the inverter shall display ------, and the user can only enter the menu after inputting the user password. Otherwise, the user cannot enter. If the user wants to cancel the password protection function, F3.00 should be set 0. 4.5 Auto Tuning of Motor Parameters (Refe r to F1.11)NoteThis function is invalid for DZB200 Series.

Chapter 5 Function parameters listDZB300series inverter function parameters, which are grouped by functions, have F0-F6 total 7 groups. Each function group includes a number of function codes, which adopts three-stage me nu, for instance, F4.08means the 8th function code of F4th function. For the convenience of setting function code by using operation panel, the function group number is corresponding to Stage 1 menu, the function code is corresponding to Stage 2 menu and the function code parameter is corresponding to Stage 3 menu. 1. The column of function table is described as follows: The 1st column Function Code is the function parameter group and parameter code. The 2nd column Name is the complete name of the function pa rameter. The 3rd column Setting Range is the effective setting value ra nge of the function parameter, shown on the opera tion panel LCD. The 4th Default is the original factory setting value of this function parameter. The 5th Modification is the modification perf ormance of the function paramete r (i.e. whether or not it is permitted to modify and the modification c onditions), explained as follows, : indicates that the setting value of this parameter can be modified when the inverter is either in stop or ope rating status; : means that the setting value of this parameter cannot be modified when the inverter is in operating status; **: means that this parameter is a test value which cannot be modified. (Inverter has done the automatic detection restriction to the modification performance of each parameter, helping user to prevent mis-modific ation.) The 6th column Serial No is the number of function code at the storage inside. 2.Default indicates the value of the function c ode after it is refreshed while doing the manipulation of res toring the factory parameters; but the actually dete cted parameters or record values cannot be refreshed. 3.In order to effe ctively protect the parameters, the inverter provides the cryptoguard for the function code. Af ter the users password is set up (i.e. users password F3.00 parameter is not 0), when the user press PRG button to enter function code edit status, the system first enters the users password ve rification status, dis playing ----- , and the operator must input correctly the users password, otherwise it is impossible to enter. At the state that the cryptogua rd is not locked, the users password can be modified at any time, and the one finally input will be the users password. If F3.00 is set as 0, the users password can be cancelled; when the power is on, if F3.00 is not 0, parameters are protected by password. 4. When modify parameter using serial communic ation, usage of user password also abide above principle.

Before running the inverter that has sele cted the vector control mode, accurate motor nameplate parameters must be input to the inverter correctly. DZB300 inverter will configure the standard motor parameters according to the nameplate parameters. Vector control mode is highly dependent on the motor pa rameters and corre ct parameters must be acquired for achieving good control performance. Motor auto tuning procedures: Firstly set the comma nd source (F0.01) as the operation panel command channel. Then input the following parameters according to the actual parameters of motor: F1.01Rated power of motor F1.02Rated freque ncy of motor F1.03Rated speed of motor F1.04Rated voltage of motor F1.05Rated current of motor If the motor is disconnected from the load completely, select 1 (complete tuning) in F1.11, and press RU N in keypad, the inverter will calculate the parameters below automatically: F1.06Stator resistance F1.07Rotor inducta nce F1.08Leakage inductance F1.09Mutual inductance F1.10Excitation current with no load Motor tuning is finished automatically. If the motor cannot disconnect from its load, set F1-11 to 2(static tuning), and then press the RUN. The inverter will measure the stator resistance, rotor resistance and leakage inductance in sequence, but it will not calculate the mutual inductance and the excitation current with no load, and the user can us e the nameplate parameters that are rated voltage U, rated current I, rated frequency f and power factor to calc ulate these two pa rameters: The calc ulation methods of the motor current with no load and the mutual inductance are described as follows. Excitation current with no load: Mutual inductance calculation:

I 0 =I.1-2 L m = 23f . I -L6 0U

Where I 0 is the excitation current with no load, L m is the mutual inductance and L 6 is the leakage inductance.

This function is mainly used to improve the motor operating noise and inverter interference to external. The advantages of using high carrier frequency: relatively ideal current wave shape, less harmonic current wave and low motor noise; The disadvantages of using high carrier frequency: increased switch loss and inverter temperature rises, affecting inverter output capacity so that it should be operated at derating under high carrier freque ncy conditions; in the mean time, inverter leaka ge current and its e lectromagnetic interference to external are increa sed. The situations of using low carrier frequency is on the contrary. Too low carrier frequency can c ause operation unstable, torque reduced and even oscillation at low frequency. When inverter is factory released, its ca rrier frequency has been set properly. Generally the user does not need to modify this parameter.

0: Operating at default direction. When the inverter is power connected, it operates at the ac tual direction. 1: Operating at reverse direction. By means of changing the function code, the motor rotati ng direction can be changed without changing any other parameters, which is equivalent to change the motor rotating direction by exchanging any two of motor cables (U, V, W). Note: After the parameters are initialized, the motor operating direction can be restor ed to be its original state. Be caution to use it in the case that changing motor rotating direction is forbidden after the system commissioning is completed. 2: Forbid inverse operating. Forbidding inverter inverse operation is sui table to specific application that inverse operating is forbidden.

Torque booth can improve the low frequency torque performance of V/F control. Based on the load, a torque should be chosen properly. For heavy loa d, increase the tor que boost, but the torque boost should not be set too big, which will result in the motor operating at overexcitation and that it could be overheated, and also the inverter output current is big, reducing efficiency.

Terminals which a re not used can be set to be no function in order to prevent malfunction The inverters forward or reverse running can be cont rol by external terminals. By means of this terminal the inverters operation mode can be defined to be three-wire control mode. For details, please refer to the function code description of F2.07 three-wire control mode. At Jogging operation, the frequency and Jogging Acceleration/Deceleration time can be found in detail descriptions of F4.02,F4.03 and F4.04 function codes. The inverter turns off output, and the motor stop process is not controlled by the inverter. It is often applied when the inertia loading is big and there is no requirement on stop time. This mode has the same definition as F0.19 does. This is external failure reset. It has the same function as STOP button on the keyboard. Using this function can perform long-distance failure reset.
