AM882 strange sensorless stall detection issue

[Mammoth 01]

Hi Gotty,

Yes It is all set up that way. I have installed +5v to Dir= and Pul+. I am not using the enable or Alm but wondering if I have to run a +5 V to the enable. The drive shows no errors and is blinking green ready to go. Like I was saying its weird I can run the motor from the Pro Tune pulser but not my Mach3. I know that the box in pro tune Dir DEF has some play in this. I believe that I have it selected low. I have wrote the eepromp as well. I will try to reset the drive in Pro tune and put all the switches in the default next, and re set up the pro tune. I have tried so many different combinations its driving me nuts.

Thanks

A corretion in my typing that was DIR+

If the green light is flashing then its good to go and you dont need to worry about the alarm and enable for now.

One clear difference running from mach and pro tune, is pro tune is going direct into the drive where as mach is going via the bob. From your description, your feeding +5 to step and dir pins on the drive and im guessing the step and dir - pins go into your bob? Are you sure the bob is wired right? ie is the dir - ment to be wired into the bob, meaning its syncing and not sourcing?
