The User Manual of 580 Series General Frequency Converter

4.9.1 Motor parameter to be set

When the frequency converter is operated in “vector control” (F0-01=0 or 1) mode, the dependence on accurate motor parameters is quite high, which is an important difference from “VF control” (F0-01=2) mode. For good driving performance and operating efficiency, the frequency converter must get accurate parameter of the controlled motor.

The required motor parameters include (The function code of Motor 1 is in default):

Parameter of Motor 1	Parameter description	Remarks
F1-00	Motor type	Asynchronous, frequency asynchronous, synchronous
F1-01～F1-05	Rated power/voltage/current/ frequency/speed of the motor	Model parameter, manual input
F1-06～F1-20	Equivalent stator resistance, inductive reactance, rotor inductance and others in the motor	Tuning parameter
F1-27～F1-34	Encoder parameter, the setting is required if sensor vector mode is available	Encoder parameter

For the complex application system of multiple motors, the corresponding parameters of Motor 2/Motor 3/Motor 4 shall include:

Parameter of Motor 2	Parameter of Motor 3	Parameter of Motor 4	Remarks
A2-00	A3-00	A4-00	Asynchronous, frequency asynchronous, synchronous
A2-01～A2-05	A3-01～A3-05	A4-01～A4-05	Model parameter, manual input
A2-06 ～A2-20	A3-06 ～A3-20	A4-06 ～A4-20	Tuning parameter
A2-27 ～A2-34	A3-27 ～A3-34	A4-27 ～A4-34	Encoder parameter

4.9.2 Automatic tuning and identification of motor parameter

The methods in which the frequency converter can get the electrical parameter of the controlled motor include: dynamic identification, static identification, manual input of motor parameter and other methods.

Identification mode	Application	Identification effect
No-load dynamic identification	Suitable for synchronous motor and asynchronous motor; the situation in which it is easy for the motor and application system to break away	The best
Load dynamic identification	Suitable for synchronous motor and asynchronous motor; the situation in which it is not easy for the motor or application system to break away	Ok
Static identification	Only suitable for asynchronous motor and the situation in which the motor is quite difficultly broken away from the load and the dynamic identification is not allowed	Bad
Manually input parameter	Only suitable for asynchronous motor and the situation in which it is not easy for the motor or application system to break away. The parameters of motor in the same type, which are identified successfully before, are input to corresponding function codes F1-00~F1-10	Ok

The automatic tuning of motor parameter shall be finished in the following steps:

The parameter identification method of Motor 1 in default is taken as an example for explanation and the identification method of Motor 2/3/4 is the same with identification method of Motor 1, but function code No. shall be changed accordingly.

Step 1: If the motor can be fully separated from load, the motor shall be separated from load mechanically after the power is cut off to make the motor in free rotation with no load.

Step 2: After the power is on, the command source (F0-02) of frequency converter is firstly selected to be the command channel of operation panel.

Step 3: Accurately input motor parameter on the nameplate (e.g. F1-00 ～F1-05). Please input the following parameters according to actual parameters of the motor (Selected according to current motor):

Motor selection	Parameters
Motor 1	F1-00: motor type selection F1-01: rated power of motor F1-02: rated voltage of motor F1-03: rated current of motor F1-04: rated power of motor F1-05: rated speed of motor
Motor 2	A2-00 ~ A2-05: The same as defined above
Motor 3	A3-00 ~A3-05: The same as defined above
Motor 4	A4-00 ~ A4-05: The same as defined above

Step 4: In case of asynchronous motor, F1-37 (For tuning selection, the Motor 2/3/4 corresponds to Function Code A2/A3/A4-37) will be available. Please select 2 (The asynchronous motor is completely tuned) and press ENTER key for confirmation. At this moment, the keyboard will display TUNE, as shown in the following figure:

Then press RUN key on the keyboard, the frequency converter will drive the motor for acceleration, deceleration, forward running and reverse running. The running indicator light will be on and identification will be continued for about 2 minutes. When the said display disappears, the machine will return to normal parameter display state, which indicates that tuning is finished.

Upon complete tuning, the frequency converter will calculate the following motor parameters automatically:

Motor selection	Parameters
Motor 1	F1-06: stator resistance of asynchronous motor F1-07: rotor resistance of asynchronous motor F1-08: Leakage inductive reactance of asynchronous motor F1-09: Interaction inductive reactance of asynchronous motor F1-10: No-load current of asynchronous motor
Motor 2	A2-06 ~ A2-10: The same definition as above
Motor 3	A3-06 ~ A3-10: The same definition as above
Motor 4	A4-06 ~ A4-10: The same definition as above

If the motor can not be separated from load completely, please set F1-37 (Motor 2\3\4 corresponds to A2\A3\A4-37) to 1 (The tuning of asynchronous motor will be stopped), then press RUN key on the keyboard panel and start the identification of motor parameters.

About the identification of synchronous motor:

The synchronous motor system driven by 580 needs encoder feedback signal and the encoder parameter shall be set correctly before identification; there must be rotation in the identification of synchronous motor system, the best identification mode is no-load dynamic identification, but the load dynamic identification can be also used if the conditions are not available;
