well , i have at least got the spindle running and stopping (the correct way)) from the reset button in mach 3. i emailed Gary @ ZAPP and apparently i need to wire in 10 v from the VFD to the BOB. i'll give it a go.

No using Reset is not the correct way to start/Stop spindle.

I also think Gary as got this wrong. The 0-10V signal is generated by the BOB you don't need the 10V from VFD.

I'm a little busy at minute but I will look at this for you later.

Ok well looking at the manual again then Gary is correct and you do need to supply the Bob with 10V for speed control, which is poor IMO but not a problem.

Regards the Relays I think you may need to change SW1 to Off and work in Enable Mode not Charge pump mode for the Relays to work correctly.
The manual isn't very clear on this but that's what I think it's trying to say.? . . . . Give it a try and see what happens.

The way the Spindle should Start & Stop is with issuing M3 for CW, M4 for CCW and M5 to stop from G-code or MDI. Or with on screen button or F5.

I think the service is slipping Dean, expecting people to wait one hour. ..Clive

i 'm having no success with the spinde control from Mach 3 . i think i have all the settings correct . i have looked online for a basic run down of the set up because i'm a complete novice but cannot find a suitable '' VFD to MACH 3 '' for dummies!! if i could at least get my basic understanding of how the various bits communicate and interact i might be in a position to fault find further , so i'm going to list my understanding of how i think it all interacts and hopefully if i am wrong or have left any thing out i can be put straight...........

1 ... change PD001 from 0 to 1... on VFD

SPEED CONTROL
2...connect GND from XP24(PWM on BOB) to ACM GND on VFD
3... connect FIV from XP24( PWM on BOB) to VI on VFD
4... connect +10v from XP24 to +10v on VFD.
the 10 v signal is from VFD to BOB for speed control. (courtesy of Jazz)



START /STOP
5... relay on BOB ( COMMON TERMINAL) to DCM on VFD
6... relay , BOB ( N.O. ) to FOR on VFD




MACH 3 OUTPUTS
i had 3 outputs left from 12 on the XP21 ( LPT PORT) pinout
I used pin 14 for the PWM (output 1) and pin 16 for RELAY 1 ( output 2)
