Parallel Port breakout boards, motherboards, and dedicated accessories / Can't get spindle to change direction.

« on: November 06, 2016, 08:31:08 PM »

ESS, PMDX-126, PMDX-107, MachIII, Lenze VFD. I set it up per AN002. It runs forward only with both M3 and M4. The direction LED on the 107 doesn't come on with either command. I've verified that the VFD will reverse. Using port 1, pin 16 for run, port 1, pin 14 for direction. Seems that it is probably a software thing, ie incorrect setup in Mach. I've attached my xml, and everything works except for reversing the spindle. Eventually, it will be closed loop, using a sensor on the spindle.

Hopefully I've done something stupidly simple again!

Parallel Port breakout boards, motherboards, and dedicated accessories / PMDX 126 Rev C jumbo mode not working.

« on: October 30, 2016, 10:29:48 PM »

I have tried all DIP configurations for switches 4, 5 & 6. One activity LED on J5 C & D turns and stays on at power up. When axis 1 is activated, both LEDs on J5 come on and stay on in one direction. The other direction, one goes out but comes back on when the axis stops. When not in jumbo mode, I can move that axis by properly configuring in Mach III.

Any help appreciated!
