4.2 I/O Signal Connections

This section describes the names and functions of I/O signals. Also terminal layout and connection examples

by control method are shown.

4.2.1 I/O Signal Names and Functions

The following table shows the names and functions of I/O signals.

(1) Input Signals

Note: With the Reverse Run Prohibited and Forward Run Prohibited functions, the processing required to stop the SER-

VOPACK is executed by the software. In some cases, the safety specifications of an application may not fulfill the

safety standards. Add external safety circuits as necessary.

Provide an external power supply; the SERVOPACK and INDEXER Module do not have

an internal 24-V power supply.

Yaskawa recommends using the same external power supply as that used for output cir-

cuits. Confirm the characteristics of relays and other mechanical contacts before using a

power supply.
