Sync Input Connector (J10)
Sync Input signals are connected to the drive using the 9-pin Sync Input connector.
If interfacing the drive using field wiring, the optional standard terminal interface board (STI-SNCI) may be used.

The Sync Input power meets EMC emissions and immunity for cables longer than 3 meters [10 ft], when using a
shielded cable. When a remote encoder is user, cable length may be limited by encoder supply voltage drop, and
should not exceed 200 ft [60 m].
