•
Since C5-05 can’t be changed during operation, stop the Inverter’s operation and then decrease the
ASR limit by 0.5 (%).
•
Perform step 3 again after the setting has been changed.
•
The ASR limit is the frequency limit for compensation by speed control. Set this frequency limit
as a percentage of the maximum output frequency.
•
If the frequency limit is lowered too much, the motor speed might not reach the target speed. Verify
that the target speed is reached during normal operation.
