Output Signal Connections
Connect the sequence output signals as shown in the following figure.
Note: Provide a separate external I/O power supply; the servo amplifier does not have an internal 24V
power supply. Yaskawa recommends using the same type of external power supply as that used for
input circuits.
Function allocation for some sequence output signal circuits can be changed.
See 5.3.4 Output Circuit Signal Allocation for more details.
