Possible causes of failure

Fault countermeasures

oCI

Over current when inverters speed up

 

The load is too heavy and the acceleration time is too short.

Extend acceleration time

V/F curve is not suitable

博乐彩票开奖Adjust V/F curve settings.

Restart the rotating motor

Set to check speed restart function

Torque set value is too large

博乐彩票开奖Adjust manual torque to automatic torque

Inverter power is too small

Use inverter with high power

oCd

Over current when inverters slow down

 

 

 

 

 

 

Deceleration time is too short

Extend deceleration time

Potential load or large inertia load

Increase the braking power of the external energy consumption brake

Inverter power is small

Use inverter with high power

oCo

Over current when the inverter is running at constant speed

Sudden change in load

Check or reduce the load mutation
