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.

For details on the MR-J2(S) servo amplifier, such as the tolerance for the internal power and operation of the servo
amplifier, refer to the following manual.
To detect absolute positions, connect this line to the PLC.
Set the pulse output method using the pulse output method setting switch.
