output torque will increase. It needs to use torque limit (P4-02, P4-03) and torque limit output signal
/CLT.
3. As the dimension of workpiece is larger than standard, offset pulse will remain in servo when the
symmetrical point is found. /CLR signal can clear the pulse. The servo motor running distance is
different from PLC pulse number. If it needs to know the actual distance, servo encoder feedback
/A+, /A-, /B+, /B- and AB phase count are needed.
4. The motion direction of A and B.

Debug
1. Initial debug
(a) Connect the cables correctly. Connect U, V, W, PE one-to-one, don’t cross them.
(b) open-loop test-running: power on, set F1-01=1, check if the motor can work normally. If yes, enter
F1-00. If not, check the cables.
(c) Jog test-running: enter F1-00. Press ENTER to enable the motor. Press INC for forward jog, press
DEC for reverse jog. Press STATUS/ESC to quit the jog running.
