120%~150% 150%
When the output current exceeds the overcurrent stall protective current during
acceleration/deceleration of the AC drive, the AC drive stops acceleration/deceleration and
keeps the present running frequency. After the output current declines, the AC drive
continues to accelerate/decelerate.
PA.05 (Overcurrent stall gain) is used to adjust the overcurrent suppression capacity of the
AC drive. The larger the value is, the greater the overcurrent suppression capacity will be. In
the prerequisite of no overcurrent occurrence, set PA.05 to a small value.
For small-inertia load, the value should be small. Otherwise, the system dynamic response
will be slow. For large-inertia load, the value should be large. Otherwise, the suppression
result will be poor and overcurrent fault may occur.
