3.3 Connecting the Inputs and Outputs
3.3.1 Step & Direction Inputs
The STRAC2 Step Drive has two high speed optically isolated inputs called STEP and DIR. They accept 5 to 24 volt single-ended or
differential signals, up to 2MHz. The maximum voltage that can be applied to the input is 28V.
The motor executes one step when the STEP input closes.
The direction of rotation is controlled by the DIR input state. A closed input (logic “0”) will result in clockwise rotation, and an open
input (logic “1”) will result in counterclockwise rotation.
