3.3.2 STEP & DIR Digital Inputs
The TSM24 drives include two high-speed inputs: X1/STEP and X2/DIR. They accept 5 to 24 volt
single-ended or differential signals, up to 2 MHz. Typically 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 “following” applications. Or you can use these inputs with Wait
Input(WI), Feed to Sensor(FS), Seek Home(SH) and other SCL or Q commands.
The diagrams below show how to connect the STEP & DIR Inputs to various commonly used
devices.
