0 10V Output Module - bdring/6-Pack_CNC_Controller GitHub Wiki

This can be used with spindle controllers that require a 0-10V analog voltage for speed control. It also has (2) opto isolated digital outputs that can be used for signals like direction. It has a potentiometer to adjust the output voltage, so it can be used with 3.3V and 5V signals. With a 3.3V signal the full speed output can be adjusted with the potentiometer from 4.75V to 11V. It has (3) LEDs to indicate the status of the outputs. The brightness of the LED on the spindle output pin will be proportional to the 0-10V output. It has a pluggable terminal block that can be installed horizontally or vertically.

Note: Ignore if "Use spindle type PWM" is written on back of module.

*Note: This module uses the VMot voltage. VMot should not exceed 32V is you install this module.

This module should be used in sockets $3 and #4 only, do to the pin properties of the other sockets.

Setup

Make sure the following settings are correct

  • $Spindle/Type=10V
  • $GCode/MaxS=24000 (your max RPM)

The output voltage has to be tuned to 10V. Connect USB and the primary voltage (12V-24V). Connect a voltage meter to the ground and 10V terminals. With Grbl in Idle, send M3 S24000 (assuming 24000 is your max speed). Adjust the potentiometer until meter reads 10V.

Wiring

CNC I/O Module VFD Description
Grn ACM Analog Common
0-10V VI signal voltage input
Com DCM Digital common
Out1 FOR Forward Direction Signal
Out2 REV Reverse Direction Signal (Optional)

If there is a jumper, make sure it is on the VI side. VR is for a potentiometer that is often on the control panel.

Testing

Make sure the rotation of the spindle is correct. It is is not, see your manual on how to fix it.
