The communication error between the encoder and the WRCA01 circuit board.
• The wrong wiring of the encoder wire
• The type of motor was not correct.
• Defective WRCA01 circuit board
• Defective encoder• Turn the power off then back on.
• If the error occurs again, replace the motor(encoder) for the axis where the error occurred.
• The control power supply was turned on
when the encoder was rotating(400rpm or more). Turning on the control power supply can not be done when the motor is rotating. • The no brake axes, R,B,T axis for SK6, freely fell when the servo power supply was turned off by emergency stop. When the power supply was turned back on this status, this alarm occured. • In case this alarm occuredin a stop state, it is thought that the encoder caused the error. • Check the timing of turning on the control power supply. • If the error occurs when the control power supply is turned in a stopped state, replace the motor(encoder) displayed on axis data.
The internal parameter of the serial encoder became abnormal.
It is thought to be an error of the encoder. Turn the power off then back on. If the phenomenon occurs again after repeating this operation several times, replace the motor(encoder) for the axis where the error occurred. 1329 DEFECTIVE SERIAL ENCODER COMMAND Robot/Station [Axis Data] When the encoder backup error occurred, normally the controller automatically resets the data of the encoder. But, this was the case there was no response of the reset completion from the encoder. It is thought that the encoder was abnormal. Turn the power off then back on. If the phenomenon occurs again after repeating this operation several times, replace the motor(encoder) for the axis where the error occurred.
