Note 1. Signal can be assigned for these pins with the controller setting.
For contents of signals, refer to the instruction manual of the controller.
2. This is for the sink I/O interface. For source I/O interface, refer to section 3.8.3.
3. In the initial setting, CINP (AND in-position) is assigned to the pin. You can change devices of the pin with [Pr. PD08].
4. The illustration of the 24 V DC power supply is divided between input signal and output signal for convenience. However, they
can be configured by one.
The 24 V DC power for I/O signal, use power other than 24 V DC power of servo amplifier control circuit power supply.
