The external power supply input terminal is common to sequence input signals.
Contact input signals: /DEC (CN1-41)
P-OT (CN1-42)
N-OT (CN1-43)
/EXT1 (CN1-44)
/EXT2 (CN1-45)
/EXT3 (CN1-46)
 Output Signal Connections
Connect the sequence output signals as shown in the following figure. (Standard settings)
Provide a separate external I/O power supply; the SERVOPACK does not have an internal 24-V power
supply. Yaskawa recommends using the same type of external power supply as that used for input cir-
cuits.
