5 Basic Operations and Trial Run

Auto-tuning methods are described below.

Motor 1 is used to describe motor auto-tuning methods. If you need to perform motor 2 auto-tuning, set F0-

24=1.

Step 1: If the motor can be disconnected from load, cut off the power, disconnect the motor from load to let the

load runs in idle.

Step 2: Power on the AC drive. Set F0-02 = 0 to select the operating panel as running command.

Step 3: Input motor nameplate parameters (F1-00 to F1-05) correctly. Set the following parameters according

to the motor:

Motor Parameter

Motor 1

F1-00: Motor type selection F1-01: Rated motor power

F1-02: Rated motor voltage F1-03: Rated motor current

F1-04: Rated motor frequency F1-05: Rated motor speed

Motor 2 A2-00 to A2-05 have the same denition.

If there is an encode, set F1-27, F1-28, and F1-30.

Step 4: For the motor is an asynchronous motor, set F1-37 (A2-37 in case of Motor 2) to 2 and press ENTER.

TUNE is displayed, as shown in the following gure:

Press RUN on the operating panel. The AC drive drives the motor to accelerate/decelerate and run in forward/

reverse direction. The RUN indicators becomes ON and auto-tuning lasts for about 2 minutes. After the pre-

ceding display disappears and the operating panel returns to normal parameter display state, it indicates that

auto-tuning is completed.

After auto-tuning, the following motor parameters are calculated:

Motor Parameter

Motor 1

F1-06: Stator resistance F1-07: Rotor resistance

F1-08: Leakage inductive reactance F1-09:Mutual inductive reactance

F1-10:No-load current

Motor 2 A2-06 to A2-10 have the same denition.

If motor cannot be disconnected from load, set F1-37 (A2-37 in case of Motor 2) to 3 and press RUN on the

operating panel. Auto-tuning starts.
