Configuring the Control Software:
It is strongly recommend you read your control software’s manual. You need to
configure your control software to control the spindle as if it was an angular axis.
This card requires a 25 KHz input signal in the pin 14 to deliver 10VDC. So you
have to set the speed of the motor (spindle) at maximum. For acceleration values
adjust them to where you feel comfortable. Keep in mind the acceleration of the
motor must also be set in your VFD.
For configuring Mach follow these steps:
1. Go to Config / Ports&Pins / Motor Outputs. Enable the spindle and select the port
and pins you wired for step and direction.

2. Go to Config / Ports&Pins / Spindle Setup. In the motor control box, check Use
Spindle Motor Output and Step /Dir Motor. Under Pulley Ratios set the pulley
ratios of the machine.
