Example Connection
*3. To ensure safety, use the forward rotation limit switch and the reverse rotation limit switch on both sides: the PLC side and
the servo amplifier side. Note that the limit switches on the PLC side should be activated slightly earlier than the limit
switches on the servo amplifier side.
Reverse rotation limit 2
(Servo amplifier side)
