1) In acceleration, the inverter will delay the acceleration time if the time is too short resulting in the
over current in order to prevent the inverter trips.
2) In deceleration, the inverter will delay the acceleration time if the time is too short resulting in the
over voltage of DC VUS in order to prevent the inverter trips with ‘OV’ displayed.
3.)Some mechanical characteristics (such as press) or unusual breakdown (seize due to insufficient
lubrication, uneven operation, impurities of processed materials, etc.) will cause the inverter to trip,
thus inconvenience users. When the operating torque of the inverter exceeds the setting of 07-03,
the inverter will lower the output frequency following the deceleration time , and return to the normal
operation frequency after the torque get steady.
