Offline auto-tuning consists of the following five steps:
• Presetting of parameters
• Selection of motor rotation during auto-tuning
• Auto-tuning
• Operations after auto-tuning
• Operations in case of error
1 Presetting of parameters
(1) Set the 1st Motor Capacity (H003) and the 1st Motor Pole Number (H004) according to
your motor.
(2) Set the 1st Base Frequency (A003) to the rated frequency of the motor and the Motor
Rated Voltage Selection (A082) to the rated voltage of the motor.
(3) Change the DC Injection Braking Selection (A051) from 01 (Enabled) to 00 (Disabled).
If the DC Injection Braking Selection (A051) is set to 01 (Enabled), change it to 00
(Disabled). If it is set to enabled, auto-tuning will not complete.
(4) Set the Output Voltage Gain (A045) to 100%.
This parameter is set to 100% by default. Restore it to 100% if the data is different.
(5) Make sure that the torque reference input permission terminal (52: ATR) is OFF.
Correct measurement is not possible when the terminal is ON.
