■ Automatically Set E2-02 [Motor Rated Slip] and E2-03 [Motor No-Load Current]
After Stationary Auto-Tuning is complete, use this procedure to do the operation in test mode:
1. Check the E2-02 and E2-03 values on the “Modified Parameters/Fault Log” screen or the “Parameters” screen.
2. Operate the motor in Drive Mode with these conditions:
• Uncouple the motor from the load
• Make sure that you connect all wiring between the drive and motor
• Make sure that a mechanical brake on the motor shaft is not locked
• Keep a constant speed of 30% of E1-06 [Base Frequency] (default value = maximum frequency) or more
for 1 second or longer.
3. After the motor stops, examine the values of E2-02 and E2-03 again in the Verify Menu or Parameter Setting
Mode.
4. Make sure that the input data is correct.
When the settings in E2-02 and E2-03 are different than in step 1, the drive set the values automatically.
