P3.1.2.14 OVERMODULATION (ID 1515)
Overmodulation maximises the output voltage of the drive, but increases the motor current
harmonics.
P3.1.3.1 MOTOR CURRENT LIMIT (ID 107)
This parameter tells the maximum motor current from the AC drive. The range of values for
the parameter is different for each frame size of the drive.
When the current limit is active, the drive output frequency is decreases.
NOTE!
The Motor Current Limit is not an overcurrent trip limit.
