Overcurrent Stall Prevention Function

・Overcurrent stall prevention function:
During acceleration/deceleration, if acceleration/deceleration time is too short
for the inertial load and the output current exceeds OCS level, the parameter
serves to extend acceleration/deceleration time.
・Overcurrent trip prevention function:
If overcurrent occurs in the inverter during operation, output will be
temporarily stopped and started again when the current drops to normal level.

・When load fluctuates drastically or the inverter accelerates or decelerates
sharply, instantaneous overcurrent may sometimes lead to trip.
・For 200 V/0.75 kW inverter, if the carrier frequency setting is higher than 7.5
kHz, overcurrent trip prevention function will become invalid.
・For 200 V/1.5 kW inverter, if the carrier frequency setting is higher than 5
kHz, overcurrent trip prevention function will become invalid.
・For 3.7 kW inverter, if the carrier frequency setting is higher than 10 kHz,
overcurrent trip prevention function will become invalid.
・The operation level of overcurrent stall prevention function can be set with
parameter "P021: OCS Level". The factory setting is 140% of rated current.
