GE DS3800NTRD1F1F Relay card

The break of the signal wire from encoder (But, this alarm may accompany the position error alarm, the alarm related to the encoder.) • Noise of outside equipment • Defective WRCA01, WRCF01 circuit board • Decrease of the power supply voltage for the encoder • Defective motor(encoder) • Check the conduction of cable from the WRCA01, WRCF circuit board to the motor(encoder). • Check whether there is equipment generating loud noise. • Check the grounding of controller is correct. • If the error occurs again, replace WRCA01 and/or WRCF01 circuit board. • Replace the motor for the axis where the error occurred.

SPEED WATCHER BOARD ERROR 

The error occurred in the speed detective circuit board. • Defective speed detective circuit board • Defective WRCA circuit board • Turn the power off then back on. • If the error occurs again, replace the speed detective circuit board and WRCA01 circuit board.The power supply voltage of direct current supplied to the amplifier of servopack exceeded 420V. • The primary power supply voltage was too high.(220V,+10%) • It was too much load. • Defective converter • Defective WRCA01 circuit board

GROUND FAULT Robot/Station

One of U,V,W wires of the motor displayed on axis data was grounded at least. • Defective the motor • Ground fault of the motor, lead wire • Defective WRCA01, WRCF01 circuit board • Defective 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. • Remove the U,V,W,E wires of the motor from the terminal of the controller and check the conduction of U-E, V-E, W-E. If the wires are conducted, it's abnormal.
