TROUBLESHOOTING 

MVE User Manual (710-17074-00G) | 

71

 

Symptom 

Probable Cause 

Motor does not reach full speed. 

•

 

If the start current is too low, the motor will not produce enough torque to 
accelerate to full speed. The soft starter may trip on excess start time. 

 

NOTE 
Make sure the motor starting parameters are appropriate for the 
application and that you are using the intended motor starting profile. If a 
programmable input is set to Motor Set Select, check that the 
corresponding input is in the expected state. 

•

 

The load may be jammed. Check the load for severe overloading or a locked rotor 
situation. 

Erratic motor operation. 

•

 

The SCRs in the MVE require at least 5 A of current to latch. If you are testing the 
soft starter on a motor with full load current less than 5 A, the SCRs may not latch 
correctly. 

Soft stop ends too quickly. 

•

 

The soft stop settings may not be appropriate for the motor and load. Review the 
soft stop settings. 

•

 

If the motor is very lightly loaded, soft stop will have limited effect. 

Remote start/stop command is 
overriding Auto-Stop settings when using 
remote two-wire control. 

•

 

Auto-Stop should only be used in remote mode with three-wire or four-wire 
control. 

Parameter settings cannot be stored. 

•

 

Make sure you are saving the new value by pressing the STORE button after 
adjusting a parameter setting. If you press EXIT, the change will not be saved. 

•

 

Check that the adjustment lock (parameter 15B) is set to 

Read & Write

. If the 

adjustment lock is set to 

Read Only

, settings can be viewed but not changed. You 

need to know the security access code to change the adjustment lock setting. 

•

 

The EEPROM may be faulty on the controller. A faulty EEPROM will also trip the 
soft starter, and the controller will display the message Parameter Out Of Range. 
Contact your local supplier for advice. 

 ATTENTION! Remove Mains Volts 

•

 

The soft starter will not activate Run Simulation with three-phase power 
connected. This prevents unintentional direct on-line (DOL) start. 

Current values shown on the display are 
incorrect. 

•

 

Check that the setting of the CT ratio selector DIP switch on the power interface 
board matches the ratio of the CT used. Refer to 

CT Current Measurement

.
