• 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.
• 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
Because the resurrection energy on reducing
the motor speed was too high, the resurrection circuit board didn't work. • The load installed on robot was too heavy. • The primary side power supply voltage was too high.(242V or more) • Defective converter • Defective WRCA01, WRCF01 circuit board • Check the load again. Lower the teaching speed of the fore and aft steps for alarm occurence step about 30% and check the reoccurence. If the alarm doesn't reoccur, alter the load. • Check the primary power supply(220V, +10%). • If the error occurs again, replace the WRCA01, WRCF01 circuit board. • Replace the converter for the axis where the error occurred.
The primary side power supply voltage of servopack
was too high.(more than 242V) • Check the primary power supply(220V, +10%). • If the error occurs again, replace the WRCA01 circuit board. • Replace the converter for axis occured the error. 1324 TEMPERATURE ERROR (CONVERTER) [Bit Pattern] The temperature of servopack(converter) was too high. • Check whether the ambient temperature is too high or not. • Check the primary power supply(220V, +10%). • If the error occurs again, replace the WRCA01 circuit board. • Replace the converter for axis occured the error
