Parameter # 27
Parameter Name Over-current stall prevention during steady-state operation
Factory Setting d0170%
Units 1%
Parameter value d0050 - d0200%
During steady-state operation with the motor load rapidly increasing, the AC drive
output current may exceed the limit specified in Pr.27. When this occurs, the output
frequency will decrease to maintain a constant motor speed. The drive will
accelerate to the steady-state operating frequency only when the output current
drops below the level specified by Pr.27. A setting of 100% is equal to the rated
current of the drive.
