The speed monitoring command cable is disconnected. • Check the connection cable of the I/O contactor unit. • Replace the WRCA01 board. 1341 BROKEN SPEED MONITOR LINE (XFC01) The error occurred in the speed monitoring level signal. • Disconnected cable between the I/O contactor unit and the XFC01 circuit board • Disconnected cable between the I/O contactor unit and the XCI01 circuit board • Defective I/O contactor unit • Defective XFC01 circuit board • Check the cable connection between the I/O contactor unit and the XFC01 circuit board. • Check the cable connection between the I/O contactor unit and the XCI01 circuit board. • Replace the I/O contactor unit and the XFC01 circuit board. • If the error occurs again, contact your YASKAWA representative.
The motor speed displayed in the axis data exceeded
the allowable maximum motor speed. • Improper wiring of motor lines U, V and W. • Wrong type of motor was used . • Motor was moved by an external force. • Defective XFC01 circuit board • Defective motor (encoder) • Check the motor wiring. • Check the robot movement when the alarm occurred to make sure that no external force has been applied. • Check the wiring of motor lines U, V and W. • Reduce the teaching speed from the speed when the alarm occurred to check if the same error will occur. With some taught postures, the R-, B-, or Taxis may operate at a high speed during linear interpolation. In this case, review the teaching.
Check that the type of motor
is same as
the one described in the manual. If the
type is not correct, replace it with the
correct motor.
