Enable Input (required)
To enable the drive and energize the motor, you must connect the enable input
(pin 1) to digital ground (pin 2), and issue a DRIVE1 command. The next drawing
shows the internal circuit.

Enable Input and Reset Input
Reset Input (optional)
The reset and enable inputs use the same circuit design, as the drawing above
shows. To reset the drive, temporarily connect the reset input (pin 3) to digital
ground (pin 2). Reset begins when pin 3 is grounded. The drive will begin its
power up sequence upon disconnection of pin 3 from ground.
VINref – Voltage Input Reference (optional)
Use VINref (pin 26) to set the input reference voltage for the enable, reset, and
digital inputs.
It is not necessary for you to make connections to VINref. If you connect nothing,
then the enable, reset, and inputs are internally pulled up to +24VDC. This is the
factory default condition.
If you connect an external 5 – 24VDC power supply to VINref, then the input
switching thresholds become:
