3.4.2 STEP&DIR Digital Inputs
The S drives include two high speed inputs called STEP and DIR. They accept 5 volt single-ended
or differential signals, up to 2 MHz. EN is a 5 to 12 volt standard digital input that can be used for
motor enable, alarm reset, or oscillator speed change.
All inputs are congured using the ST Congurator software.
STEP and DIR inputs can connect to an indexer, a master encoder or CNC hand wheel for follow-
ing applications, or they can be used for connecting sensors, switches and other electronic de-
vices. They can be used as the run/stop and direction inputs for velocity (oscillator) mode.
