Let the fun begin !!! ???

[PAULRO]

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)
