High Speed Digital Inputs
The ST Series drives include two high speed inputs called STEP and DIR. They accept 5 volt single-ended
or differential signals, up to 2 MHz. Normally these inputs connect to an external controller that provides
step & direction command signals. You can also connect a master encoder to the high speed inputs for fol-
lowing applications. Or you can use these inputs with
Wait Input, If Input, Feed to Sensor, Seek Home
and
other such commands.
