This function is set for uncertain load inertia circumstances. Deceleration over voltage shall not occur in normal load
stop, and deceleration time shall also be applicable. However, tripping shall not occur due to over voltage in
occasional load back up inertia increase stop; in these occasions, deceleration time shall be increased automatically
by the inverter to stop. This function is inapplicable provided that deceleration time disturbs application. This problem
shall be solved by increasing deceleration time or install braking module to absorb excessive back up voltage.

During operation of AC motor drive, provided that output current exceeds set value of 6-01 (Over current stall
prevention current level during running), output frequency shall be decreased by AC motor drive to prevent motor
stalling. AC motor drive shall perform acceleration again to set frequency when output current is below setting of 6-01.
Set unit shall be percentage of rated output current (100%) of the AC motor drive.
