Possible causes of failure

Fault countermeasures

oCI

博乐彩票开奖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

Adjust V/F curve settings.

Restart the rotating motor

Set to check speed restart function

Torque set value is too large

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

博乐彩票开奖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

Acceleration and deceleration time setting is too short

Appropriately extend acceleration and deceleration time

Abnormal load

Check load

Low power grid voltage

Check input power

Inverter power is small

Use inverter with high power

oUI

Over voltage when inverters speed up

Abnormal

Input voltage

Check input power

Acceleration time setting is too short

Appropriately extend acceleration time

Restart the rotating motor
