Subject: Re: [mach1mach2cnc] VFD and PWM ? ? i have read the mach3 manual section on spindle control and can not figure out how to set it up for PWM control. i have a PDMX board that does not have a dedicated PWM circuit for motor control. can i use the fourth axis that i am not using? PDMX calls this axis A or axillary output. is this controllable by mach3 as PWM spindle control? On 3/10/2015 9:48 AM, Chris microcnc_31@... [mach1mach2cnc] wrote: ? Hello: ? Can anyone tell me how the PWM signal comes out of Mach?. And if you have made connection correctly from G540?. Pin 7,8 and 9 are connected to VFD, Does pin 7 and 9 put out 12V on their own? ?
