Be sure to use the class-D grounding method (grounding resistance: 100 or less).
Near-point signal (DOG)
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.
