COMMON
Problem Possible cause Correction
Inverter tripping
Shut-off due to overcurrent
Sudden acceleration/deceleration Make the acceleration/deceleration time longer.
Sudden change in load Decrease the load change.
Grounding overcurrent Grounding on the output side Make correction to eliminate grounding.
DC overcurrent Short-circuiting on the output side
Make correction to eliminatge short-circuiting.
Check cables.
Shut-off due to regenerative
overvoltage
Sudden deceleration
Make the deceleration time longer.
Reduce the braking frequency.
Thermal relay operation Overloading Decrease the load to the specified value.
