1.) If the acceleration time is set too short, the inverter will delay the acceleration time in order to prevent an over
current trip “OC-AS”.
2.) If the deceleration time is set too short, the inverter will delay the deceleration time in order to prevent an over
voltage of DC BUS trip ‘OC-C’.
3.) Some mechanical equipment such as presses, or a mechanical failure such as seizing due to insufficient
lubrication, varying loads, etc. will cause the inverter to trip. When the operating torque of the inverter exceeds
the setting of A116, the inverter will lower the output frequency at the deceleration time set by A117, and then
return to normal operating frequency after the torque level stabilizes.
