Funny, I have the exact same CNCRP Plug and Play system and having the exact same problem with my Hitachi W200. I can get a RUN led light on but Zero speed out My email question to them today, is the ESS and board outputting 0-10 vdc (which will input on O terminal on the VDF ) or a true PWM? No answer yet...... because I do not believe that they are the same. The specs say PWM maybe either one will work. I have always used voltage in the past.

So I just got off the phone with Ahren at CRP. It turns out that I was not getting any voltage output from the breakout board. Ahren instructed me to change the step port in the motor output to 2 instead of 1. A slight problem I am having it the output is 7.8 volts and not 10 volts. I have changed the PWM but that does not seem to work. Do anyone know what parameter i can change on the VFD that would make this able to accept 0-8 volts instead of 0-10? Thank you everyone for your help. Really appreciated all your input.
PD070 = 1 will use 0-5V, but there's no way to use 0-8V.
You could always spend $10 on a USB > RS485 adapter and use a plugin to control the spindle.

Mac I think your correct. I believe the BoB that CNCRP now only uses outputs PWM Signal and you need a way to change from that to 0-10 vdc. There is a add on board that you can purchase that outputs 0-10 vdc from a PWM signal but comes or is made by folks in Korea or China. Seems the older CNCRP control panel did output voltage but not the new ones.
My Hitachi W200-022SF will take a pulse train input but the manual for this drive sucks. So is Pulse Train the same as PWM?? A phone call today to them might clear it up.
Added: So according to the updated Quick Reference guide, Pulse Train is the same as PWM. So my Hitachi should work, if Mach3 is set up correctly.

I really am not sure, its still dark and cool here (7 am) I will go out later and try to figure it out. But I did update my post, seems my drive Will indeed take a PWM signal, its as clear as mud but the new updated Quick Reference manual helped. Thanks Hitachi.
Agreed, If Mach3 outputs PWM and most of the drives are 0-10 vdc, why and the heck after all these years why has someone not changed or added it?? My guess is a perhaps a lot of people just use the speed up/down on the drive keypad.

I think you are mistaken. Their board should have a PWM to 0-10V converter on it.I believe the BoB that CNCRP now only uses outputs PWM Signal and you need a way to change from that to 0-10 vdc.
Mach3 was designed around a 5V parallel port, so it can't natively do 0-10V. That's why most breakout boards have a built in PWM > 0-10V converter. There are also several stand alone converter boards available.Agreed, If Mach3 outputs PWM and most of the drives are 0-10 vdc, why and the heck after all these years why has someone not changed or added it??

Thanks Gerry. Another user on Sawmill Creek is using PWM with his Hitachi, so I thought I had to also. I need to warm up the shop and check some voltages.
So the board is a CNCRP made product and it does say 10 vdc out.

Well I have given up for now and going back to my Hitachi router set up. Zero help from CNCRP and maybe I will gather some more info and get back to the spindle project after the first of the year.
I did get an email tonight (last night) from CNCRP so they did respond.
And Today I did get information and a PDF of the BoB they use, and it will output PWM signal 0-5 vdc (not sure if thats enough for the Hitachi W200) and a full 0-10 vdc on the two terminals marked 0-10 v out and Gnd bottom of BoB left side terminal strip. Great support at CNCRP.
