Note: 1. The functions allocated to /DEC, P-OT, N-OT, /EXT1,-/EXT2 and /EXT3 input signals can be changed by using the
parameters.
2. If the Forward/ Reverse run prohibited function is used, the software can be used to stop the Servo drive. If the application does not satisfy
the requirements, add an external circuit for safety reasons as required.

Control power supply input for sequence signals: users must provide the +24 V power supply.
Allowable voltage fluctuation range: 11 to 25 V.
Connecting pin for the absolute encoder backup battery.
Do not connect when a battery is connected to the host controller.
General-purpose input signal:
Monitored in the I/O monitor field of MECHATROLINK-II.
Connects the deceleration limit switch for homing.
Overtravel prohibited: Stops servo motor when movable part travels beyond the
allowable range of motion.
Connects the external signals that latch the current feedback pulse counter.
