Description
 Wei Ken inverter maintenance
Common faults and solutions of Wei Ken transducer
1 over current transducer detects the existence of excessive current on the motor cable (>4 * In)
Sudden and heavy load
Motor cable short circuit
Motor is not suitable
Check load
Check motor specifications
Check cable
2 over voltage inverter internal DC bus voltage beyond the specified limits
Deceleration time is too short
The device is subjected to a very high voltage peak.
Prolonged deceleration time
3 grounding fault motor detection found that the motor phase currents and is not zero
Failure of electric motor or cable insulation
Check motor cable
4 under voltage DC bus voltage drop to the provisions of the following voltage limit
The most common reason is that the power supply voltage is too low
Internal fault of inverter
If the supply voltage is temporarily interrupted, it can be reset after the restart
Check device input
The connection between the 5 panel communication failure control panel and the frequency converter is interrupted.
Inspection panel connection, the cable connection, the cable should be checked at the same time
