Anomalies |
Items to Check |
Solutions |
|
The motor can’ t rotate. |
Check if there is abnormal wiring. Be sure that power lines are connected to input terminals (R, S, T). |
Perform correct wiring. Cut off power supply and then perform rewiring. |
|
Check if bypass contactor works. Be sure terminals 01, 02 have signals. |
Check the connection of bypass contactor. Check the control and connection of the coil loop of bypass contactor. |
|
Check if there is abnormal display on the operation panel. |
Refer to page 27 “ Schedule of Protection Operating” . |
|
Check if the motor is locked or there is too heavy load. |
Unlock the motor or lighten the loads. |
|
Keyboard starting is disabled. |
Check if there is error tip on the operation panel. Be sure that the terminals 07, 10 are open and settings of the code P9 is correct. |
If no error tip is displayed, check the input power supply. If error tip is displayed, check if the terminals 07, 08 and 10 are open; check external wiring of the terminals and set parameters of P9 properly. |
|
External control starting is disabled. |
Check if the code P9 is set to external control. |
If open circuits occur among the terminals 07, 08 and 10, check external wiring of terminals; set parameters of P9 properly. Be sure external control has been set. |
|
The motor rotates but its speed cannot be raised. |
Check if there is too heavy load. |
Lighten the loads. Modify parameters; increase the inceptionvoltage or starting current. |
|
Starting time is too long. |
Check if there is too heavy load. Be sure parameter settings of the soft starter are proper and the motor model is correct. |
Lighten the loads. Set P0 (inceptionvoltage), P3 (starting limitation current) and P1 (soft start time) properly. Check model descriptions of soft starter and its specifications label. |
|
Starting time is too short. |
Check if there is light load or too short starting time. |
When there is a light load, the starting time is generally shorter than the set value. It will be normal if there is a balanced start. Set the starting time of P1. (current mode invalid) |
|
Sudden shutdown occurs during operation. |
Check external input terminals. |
Check if there is any loosen connection between the terminal 07 and 10. If there is an external protector, check if the break contact works. Check if there is loosen connecting wire of external stop button. |
