4.3 Connecting to Inputs
4.3.1 Pulse & Direction inputs
The SR Drive has two high speed optically isolated inputs called STEP and DIR. They accept
the 5 to 24 Volts single-ended or differential signals, which up to 2MHz. The max voltage that
can be applied to the input is 28V.
The motor executes one step with the falling edge of the STEP signal.
The direction of rotation is controlled by the DIR signal level. The low signal (0 level) is
clockwise rotation, and the high signal (1 level) is Counterclockwise rotation.
4.3.2 EN input
The EN input enable or disable the drive amplifier. It is an optically isolated input that accepts
5 to 24 Volts single-ended or differential signal. The max voltage that can be applied to the
input is 28V.
When EN input is closed, the driver amplifier is deactivated. All the MOSFETs will shutdown,
and the motor is free. When EN input is open, the drive is activated.
When drive is in Error status and the fault is removed from system, one falling signal into EN
will reset error status and activate driver amplifier again.
4.3.3 Connecting Circuit
Connecting to control with Sinking outputs.
Connecting to control with Sourcing outputs.
