SRX04 Hardware Manual
5.3 Connecting to the Input
5.3.1 Pulse and Direction Input
The SRX04 drives include two high-speed inputs called STEP and DIR. They accept 5 to 24 volt
single-ended or differential signals, maximum 28 volt. These two inputs have input digital filter,
2MHz or 150KHz switch selectable.
Falling edge effective for the pulse input signal.
Motor running direction is decided by the level of Direction input. When DIR input is open or under
low level, motor runs as clockwise. When DIR input is under high level, motor runs as counter-
clockwise.
5.3.2 Enable (EN) Digital Input
The EN input enables or disables the drive amplifier. It is an optically isolated input that accepts
a 5 to 24 volt single-ended or differential signal. The maximum voltage that can be applied to the
input is 28V.
When EN input is closed, the driver amplifier is deactivated, all the MOSFET s will shut down, and
the motor will be free. When EN input is open, the drive is activated.
When the drive has encountered an error and the fault is removed from system, a falling signal
into the EN input will reset the error status and activate the drive amplifier again.
