1.7.3 Corrective Action for Motor Faults 

Table 1.11 shows the check points and corrective actions of motor faults. 

 

              Table 1.11 Motor Faults and Corrective Actions 

  Fault  

   Check point 

    Corrective Action 

Power supply voltage is applied to power 
supply terminals R, S, T. 
(Check that charge lamp is ON.) 

• Turn ON the power supply. 
• Turn OFF the power supply and then 
ON again. 
• Check power supply voltage. 
• Check that terminal screws are tight. 

Voltage is output to output terminals U, V, 
W (Use rectifier type voltmeter.) 
 

• Turn OFF the power supply and then 
ON again. 

Load is excessively large. (Motor is 
locked.) 

Reduce the load. (Release the lock.) 

Fault is displayed. 

Check according to Par. 1.7.1. 

FWD or REV run command is entered. 

Correct the wiring. 

Frequency setting voltage is entered. 

˙

Correct the wiring. 

˙

Check frequency setting Voltage. 

 
 
 
 
 
 
 
 
Motor does not 
rotate. 

Operation (method selection) mode 
setting is proper. 
 

Check the operation method Selection 
mode [constant Pn-01] by using the 
digital operator. 

Wiring of output terminals U, V, W is 
correct. 

Match them to the phase order of motor 
U, V, W. 

Motor rotating 
direction is 
reversed. 

Wiring of FWD and REV run signals is 
correct. 

Correct the wiring.
