Motors run abnormally in spindle on or off.I am currently using 570 oz. steppers and set to 2000 steps, step pulse set to 2, vel. =270, accel= 70. Iam using Digital drivers and was happy with the performance. I will definitely check the grounding issue to begin with.
 thanks

Im currently using a shielded 6 conductor for the low voltage wiring from the C6 board to the vfd . Do I use the shield non insulated wire to to ground on one end or both ends.
I know at  work shielded pairs are normally grounded on one end but in this case im not sure. and would the controller case be a sufficient area to ground the wire.
Thanks Hood

General Mach Discussion / motors lose steps after vfd install

« on: July 18, 2012, 10:17:28 PM »

Finally got my vfd step/dir working and ran a code and noticed that stepper motors are now losing steps. At one moment they faulted out both digital drivers. Shut down system restarted and went into motor tuning changed a few numbers vel. accel and same problem occurs. Whats going on? Can there be some kind of noise or interference causing this issue . Kernal speed is set to 25000k . Maybe debounce setting increased not sure any help out there would be great.

General Mach Discussion / Re: cnc4pc c35 bob w/spindle control question

« on: July 04, 2012, 02:57:12 PM »

I have the C3 Index pulse hooked up to c35 and have all boards powered up. Does the c6 board go in the output on c35 via rj45 connector and will this power up the board?
And also does c6 need 2 terminals (gnd and 0-10v ) hooked up to com and 0-10v multi function analog output on my vfd to get mach to control spindle.This VFD has very poor literature so this is a little mind boggling.

General Mach Discussion / cnc4pc c35 bob w/spindle control question

« on: July 03, 2012, 11:35:33 PM »

Im currently converting  A 10x22 lathe and am using digital steppers 8056D and a c35 bob. My question is I would like to control spindle speed and also do some threading through Mach,
but am unsure on which board to use c6 variable speed control or c3 index pulse card with my Teco VFD EV series. And also what would be the best way to wire them to the vfd ??
Any help or suggestions would be greatly appreciated .

Would I still have access to to the wizards and also should i revers y z  for the 1024lathel.set in homing to be correct ?
Thanks for your expertise Hood you've gotten me out of a few binds in the past and always come up with a solution.let me give it a shot.
