  • Page 2 • VFD Maximum Current – 9.5A  This document is designed to give an overview of the wiring options for the aircooled ER20 spindle and H100 VFD products. The H100 VFD accepts several input / control wiring set ups, but only those commonly used in CNC applications will be discussed here.

  • Page 7 Page 7 of 16  Next wire the spindle to the VFD. Again, note that the protective earth (PE) is located away from the input terminals to the right of the control terminal group. The diagrams below show both the actual ‘as photographed’...
  • Page 8 Page 8 of 16  Only change the jumper settings of the drive with the power off! Changing with power connected can damage the drive. The H100 VFD comes with a series of PCB mounted jumpers. These are used to set various functional parameters on the board.
  • Page 9 Page 9 of 16  The green screw terminals of the inverter are used for the logic level input / output control between this device and your machine controller. Note that each terminal is labelled, and a description and default setting can be found in the table below. Please make sure to conncet both “GND”...
  • Page 10 Page 10 of 16  Terminals X1 (Forward) and X2 (Reverse) need to be wired to be switched remotely if you wish them to be controlled by Mach 3 and your CNC controller. The example below shows these terminals being switched via our 5V relay module, but any other relay or 12-24v DC transistor based control will work.
  • Page 11 Page 11 of 16  The breakout board supports two options for supplying spindle speed information to your spindle drive. We will use the 0-10V DC analogue signal as it is the most common method for speed control. The diagram below shows the typical wiring for the H100 VFD using the 0-10V analogue method. It is essential that the 0V rail from the VFD and the breakout board are both wired back to the common DC bus.
  • Page 12 Page 12 of 16   The rest of this manual assumes that you have your CNC controller set up and talking to your PC already. If not, go away now and get this working (see our Breakout Board user manuals for a detailed guide).
  • Page 13 Page 13 of 16  In the Motor Outputs tab, you need to enable the spindle, set the Step Pin#, Dir Pin#, Step Port & Dir Port all to 1. Click on Apply again to save! Next return to the Spindle Setup tab and enter the details below. If your VFD needs a higher than 0V minimum setting then adjust the minimum PWM setting up by 10% per volt required.
  • Page 14 Page 14 of 16 You will now need to configure your spindle pulleys to match the hardware on your machine. Find this via Config -> Spindle Pulleys.. as shown to the right. Leave the box set as Pulley Number 4 (Mach 3 doesn’t like it if you change) and then set the minimum and maximum speeds to match those that your VFD supports.
  • Page 15 Page 15 of 16  Finally, we need to set the VFD to work with external control, and with the spindle motor we are using. Below is the manufacturer recommended sequence for doing this. Please note that doing this out of order can cause problems later. If you would like to change any other settings, please refer to the H100 user manual.
