SmartBOB controllers and dedicated accessories / PMDX-422 with PMDX-407 Setup Not Working

« on: December 26, 2016, 08:00:33 PM »

I'm having trouble getting my spindle motor to run.  I've got the following setup:

PMDX 422  (connected to 3 axis motors which seem to jog correctly)
PMDX 407
Haunyang VDF (works from the front control, but not from PMDX control)
1.5HP 3 phase motor

I have configured the Mach 4 and the 422 plug in as shown in the below screen shots.

The connections from the PMDX 407 to the VDF are as follows:

A ref to 10V on VDF
A out to V1 on VDF
A  gnd to AMC on VDF
Run Com to DMC on VFD
Run  to V1 on VDF

On the Mach4 screen when the cw spindle button is selected with the slider at 100% a click is heard on the PMDX 422.   The led on PMDX 422 near K1 lights.  Neither led on the 407 lights. The spindle motor does nothing. There is 10 vdc at Aref and .335 VDC at Aout.  There seems to be .335 VDC @ Aout at all times.

PD001 is set for external terminal
PD002 is for board potentiometer and external potentiometer.
PD070 is set for 0-10v range

General Discussion / How do configure my limit switches?

« on: December 03, 2016, 08:07:11 PM »

I'm new to the world of CNC machines and just finished building a 3 axis machine.  My machine uses the PMDX 422 board with Mach4.  I think the 3 axis motors are configured ok (They jog as they should).  The E-Stop is connect to pin 10 and works.  I would like to know how to configure the limit switches.  Presently I have the -Y +Y switches connected in series to input pin 11,  -Z +Z switches connected in series to pin 12, and -Y +Y switches  connected in series to pin 13.  The input goes to 5v when the limit is reached. Also I would like to use these switches as the home switches. Can someone please advise me?  Thanks in advance
