trols, and not by electrical or mechanical means. If the application does not satisfy the safety requirements, add
an external circuit for safety reasons as required.
Function
With overtravel prevention: Stops servomotor when movable
part travels beyond the allowable range of motion.
Connects the deceleration limit switch for homing.
Connects the external signals that latch the current feedback
pulse counter.
Used for general-purpose input.
Monitored in the I/O monitor field of MECHATROLINK.
Control power supply input for sequence signals.
Allowable voltage fluctuation range: 11 to 25 V
Note: The 24 VDC power supply is not included.
Connecting pin for the absolute encoder backup battery.
Do not connect when the encoder cable with the battery case
is used.
The allocation of an input signal to a pin can be changed in
accordance with the function required.
