Super Heavy duty: 0~180% (100%: drive’s rated current) Factory Setting: 150
Only functional under VF, VFPG and SVC mode
If the motor load is too large or drive acceleration time is too short, the AC drive output current may
increase abruptly during acceleration and it may cause motor damage or trigger protection
functions (OL or OC). This parameter is used to prevent this situation.
During acceleration, the AC drive output current may increase abruptly and exceed the value
specified by Pr.06-03 due to rapid acceleration or excessive load on the motor. When this function
is enabled, the AC drive will stop accelerating and keep the output frequency constant until the
current drops below the maximum value.
When the over-current stall prevention is enabled, drive acceleration time will be larger than the
setting.
When the Over-Current Stall Prevention occurs due to too small motor capacity or in the factory
setting, please decrease Pr.06-03 setting.
When there is any problem by using acceleration time, refer to the following items to solve it.
Related parameters: Pr.01-12, 01-14, 01-16, 01-18 (settings of accel. time 1~4), Pr.01-44

It is a protection for drive to auto decrease output frequency when the motor is over-load abruptly
during motor constant operation.
If the output current exceeds the setting specified in Pr.06-04 when the drive is operating, the drive
