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 9-05,
the inverter will lower the output frequency following the deceleration time set by 9-06, and return
to the normal operation frequency after the torque get steady.
9-08： ： ： ： Electronic Motor Overload Protection Operation Mode:
0000： ： ： ： Enable Electronic Motor Overload Protection

9-11： ： ： ： Operation After Overload Protection is Activated:
0000： ： ： ： Coast-to-Stop After Overload Protection is Activated
0001： ： ： ： Drive Will not Trip when Overload Protection is Activated (OL1)
Description of the thermal relay function:
1. 9-10 = 0000 ： protect the general mechanical load, the load is less than 103% rated current, the
= 0001 ： protect HVAC load(FAN 、 PUMP...so on) ： the load is less than 113% rated current,
motor continue to run. The load is larger than 150% rated current, the motor will run
for 1 minute.(Refer to following curve(1).
the motor continue to run. The load is larger than 123% rated current, the motor will
