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

« on: January 01, 2017, 10:53:33 AM »

I found the configuration page where the spindle was set to be driven from pin 1 and removed that setting.  The PWM and Run LEDs on the 407 illuminated and a Voltage proportional to the RPM setting appeared on the Aout terminal. Also the Run com and Run contacts closed.  The spindle did not move and the VFD required a couple of parameter changes.  The spindle is now working.  I was under the impression that the K1 contact could be used at the same time as the Aout signal for optional VFD controls such On/Off, spindle dir and coolant pumps. Thanks for your help..

I have not tested the home but I know the machine will stop as soon as it reaches any of the limit switches.  I'm not sure what you mean when you say that I have the spindle set to drive on pin one.  Where is this set?
I have checked the following:
JP1 is set to the on position and the 407 is correctly oriented,  if the locating pin is supposed to in the center of the notch on the 422 connector.  I have measured the voltage of pin 26 on the 407 board and it is 4.69VDC
I tried temporarily configuring the PWM board to drive pin 16 and when the spindle button on the Mach4 screen is selected the real time pin 16 indicator does not change, it remains dark, however the pin 1 indicator turns green.

There is no response from the PWM or RUN LEDS on the 407 board when spindle button is selected.

Steve Stallings: I sent the package profile VIA private email, did you get it?

Thanks for your fast response. You are correct in assuming that Run is not connected to V1.  My message should have stated (Run to For).  I have selected the 407 option, third on the list and selected the Echo Commanded RPM reporting.  In the Mach4 configuration I have changed the min. speed to 0.0
I executed both  the M3 Sxxxx  command and the Spindle speed button with the same results no (spindle movement).  When executing the spindle command or using the spindle button,  K1 and DS4 led illuminate on the 422 board.  Neither the Run or PWM Leds on the 407 board illuminate.  I believe that the Run and Run Com are suppose to be connected to a solid state relay and close.  I don't think this is happening because I can measure 24VDC between them regardless of the on/off spindle command state.  Also on the AOUT terminal there is .359 VDC at all times regardless of the spindle on/off state.  Thanks again

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

I just set it per your instructions and and the limit switches now work.
Thanks

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
