Over-current Stall Prevention during Operation
Control Mode VF VFPG SVC Default: 0
Settings 0: Disable
0–250% (rated current of the motor drive)
 If the output current exceeds the setting specified in Pr.06-03 when the drive is operating, the drive
decreases its output frequency according to the Pr.06-04 setting to prevent motor stall. If the output
current is lower than the setting in Pr.06-03, the drive accelerates (according to Pr.06-04) again to catch
up with the Frequency command value.
