General Mach Discussion / Re: PWM on spindle
« on: March 01, 2009, 02:40:38 PM »
Thank you for the reply and advice, This is what I want to get to work http://homeshopcnc.com/HFspindle2.html , PMDX122, Pmdx 106, Andeli VFD with a 2.2Kw water cooled spindle and Mach 3, VerR2.63. I can switch the spindle on at the remote operators panel with a switch and set the speed with the potentiometer, I have also set the Manual/auto switch to Auto that will allow the computer to control the spindle. This is what I accomplished today, did get Mach3 not to show me the ”PWM bumped to minimum”
if I want to control my spindle with PWM then I should tick PWM control in spindle setup?
Picture this and please tell me the mistakes,
PMDX 122 Pin 14 connect to PMDX 106 Dir in
PMDX 122 Pin 16 connect to PMDX 106 PWM in
Output signal
output# 5 Port1 Pin 14 Active low
Spindle setup
CW M3 Output #5,Use spindle motor control, PWM Control
Motor output
Spindle enable Step pin 16, Dir Pin 14, Dir active, step low active, Step port 1, Dir Port 1
I calibrated the spindle with the trim pots on the PMDX 106 Max speed is set at 400Hz@ 24000rpm minimum speed trim pot is set full anti clock wise and the spindle is still turning at 100Hz, rpm of more than 3600.
Here I am lost like most of the time; I have selected Pin 16 at motor control as Step because of the PWM output on the Pmdx 122 and Pin 14 for direction at motor control because of the connection between the two cards. At Spindle setup: PWM base Freq ………and and Min PWM…… % suggestions on values please.
With these settings, if I activate M3 or F5 I hear an relay activates and when I M5 a relay activates again but no spindle turn,
