If a fault is detected on the servo drive or motor a corresponding fault code will be shown on the drive's LED 

display. Fault codes can also be transmitted via communication, see P0-01 and P4-00 ~ P4-04 for display on 

controller or HMI. 

  Overcurrent 

Main circuit current is higher than 1.5 multiple of motor’s 
instantaneous maximum current value. 

  Overvoltage 

Main circuit voltage has exceeded its maximum allowable value. 

  Undervoltage 

Main circuit voltage is below its minimum specified value. 

 

Z Pulse shift 

The corresponding angle of magnetic field of Z phase is error. 

  Regeneration error

  Overload 

Servo motor and drive is overload. 

  Overspeed 

Motor’s control speed exceeds the limit of normal speed. 

 

Abnormal pulse control 
command

allowable setting value. 

  Excessive deviation 

Position control deviation value exceeds the limit of its allowable 
setting value. 

 

Watch dog execution 
time out  

Watch dog execution time out. 

  Encoder error 

Pulse signal is in error. 

  Adjustment error
