NOTE
When running static tuning (Pr.01-07 = 2), users must input the no-load current to the motor. In general, the
current is 20-50% of the nominal current.
When the parameter setting is “5”, users can run the permanent motor auto tuning. By pressing the RUN
key, the system will automatically run the auto tuning. Tuned values will be loaded to Pr.01-22 (Rs),
Pr.01-23 and 24 (Ld and Lq), and Pr.01-25 (Permanent Motor Back Electromotive Force).
Permanent Motor Parameter AUTO-Tuning Procedures (Static Tuning)
1. All driver parameters are set to their Factory settings and the motor is correctly connected.
2. Input the correct value for the following parameters: Motor Nominal Current (Pr.01-17), Motor
Nominal Power (Pr.01-18), Motor Nominal Speed (Pr.01-19), and Motor Phases (Pr.01-20). Adjust
the acceleration and deceleration time according to the motor capacity.
3. Set Pr.01-07 to “5” and press the RUN key on the digital operator to immediately run motor tuning.
(Note: The motor runs slightly).
4. After tuning, check if the motor parameters (Pr.01-22 to Pr.01-25) have been tuned and
automatically added to the respective parameters.
When the parameter setting is “4”, users can run the [Motor Pole Synchronization] and PG Origin Offset
Angle auto tuning. By pressing the RUN key, the system will automatically run the auto tuning. Tuned
values will be loaded to Pr.01-27.
Motor Pole Synchronization and PG Origin Offset Angle AUTO-Tuning procedures:
1. Complete the motor parameter auto-tuning in “5”, or load the correct value to Pr.01-03,
Pr.
01-17 to
Pr.
01-25.
2. Users are advised to disconnect all loads of the motor before running auto-tuning.
3. Set Pr.01-07 to “4” and press the RUN key on the digital operator to immediately run motor tuning.
(Note: The motor runs).
4. After the auto-tuning, check if the pole and PG origin offset angle values have been automatically
loaded to Pr.01-27.

Unit: Ampere (A)
Factory setting: #.##
Settings 40-120% of the driver’s nominal current.
When setting this parameter, users can refer to the range of the motor nominal current specified in the
nameplate on the motor. Default is 90% of the driver nominal current.
Ex.: The nominal current for 7.5HP (5.5kW) is 25A, and default is 22.5A.
