Connecting Digital Inputs on the IN/OUT1 connector
High Speed Digital Inputs
All STAC6 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 follow-
ing applications. Or you can use these inputs with Wait Input, If
Input, Feed to Sensor, Seek Home and other such commands.
Connection diagrams follow.
