VFD and PWM

in ports and pins, motor output, you just set some unused pin for step and direction and then one of them (the step???) is PWM'd? i hope the PDMX board can handle a reasonably high PWM frequency on a step or direction driver.
if i select PWM control in spindle setup how would i control the second spindle that does not want PWM control? do i have to fake it some way? i am currently using M3 for the first spindle that i want to PWM and M4 for the second spindle that needs to be just on/off

Ports and pin then config is all you have to do and some additional with pully. The rest is electrical…

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?

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?

?

Thanks
