Input Signal Connections
Connect the sequence input signals as shown below.
Provide an external input power supply; the SERVOPACK does not have an internal 24-V power sup-
ply.
• External power supply specifications: 24±1 VDC, 50 mA min.
Yaskawa recommends using the same external power supply as that used for output circuits. The
allowable voltage range for the 24-V sequence input circuit power supply is 11 to 25 V. Although a 12-
V power supply can be used, contact faults can easily occur for relays and other mechanical contacts
under low currents. Confirm the characteristics of relays and other mechanical contacts before using a
12-V power supply.
The function allocation for sequence input signal circuits can be changed.
See 4.3.3 Input Circuit Signal Allocation for more details.
