If you're here you're interested in wiring up our EM61 VFD into your Onefinity / BuildBotics Controller, then you're in the right place.

 

Goal:  Wire up our VFD into the Shapeoko Controller to allow their controller to control the On/Off and speed of the spindle motor.

 

Wiring Diagram

Let's start with the wiring diagram... also see attached pdf.

 

VFD Programming

Next there's VFD programming to be considered... 

 

P0003	2	Operation Control Mode A (Run/Stop)
P0004	9	Frequency Source A (RPMs)

 

 

Controller Programming

Within your controller’s user interface, find the 3-Bar Menu -> Tool screen and change the tool-type=”PwnCNC VFD” or “EM60”.

 

 

And enter the following values:

Label	Value	Description
tool-reversed	[unchecked]	If the tool is turning in the wrong direction, this checkbox will fix it.
max-spin	24000	Maximum rpms of the motor
min-spin	0	Minimum rpms of the motor
bus-id	1
baud	9600
parity	None

 

If your control cable has been plugged in, then you’re good to go. In the Modbus Status section, “connection” should show OK letting you know it’s properly communicating.
