print icon

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   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.
