GE DS3800NTRD1F1F Relay card

• In case an error is found by the above check, remove the connector of the motor side and check again. If the wires are conducted, it is thought to be a defective lead wire. Specify the error point and replace the lead wire.

 • If the error is not caused by the lead wire, it is thought to be a defective motor. 

• If the error occurs again, replace the WRCA01 and/or WRCF01 circuit board. 

• Replace the servopack, motor for the axis where the error occurred.

Any of the three-phase current for primary 

side power supply of servopack was openphase. 

• The wrong wiring of the primary side power supply connection.

• The decrease of the primary side power supply voltage(170V or less) 

• Defective WRCA01, WRCF01 circuit board • Defective converter

• Check the connection of the primary side wiring R,S,T wires of servopack. 

• Check that the power supply voltage is more than 170V. 

• If the error occurs again, replace the WRCA01,WRCF01 circuit board. • Replace the converter for the axis where the error occurred.

One of the U,V,W wires of the motor

 displayed on the axis data was grounded at least. • Defective motor • Ground fault of the motor, lead wire • Defective WRCA01, WRCF01 circuit board • Defective amplifier • Overheating of amplifier This alarm does not occured by turning off the controlled power supply. But never fail to turn on the servo power supply after checking the motor grounding. There is a possibility the servopack is damaged when the servo turn-on and off is repeateduring ground fault status. • Check the connection of the U,V,W,E wires of motor again.
