I have a DMM servo used for my spindle and control that via 0-10v analog. I noticed this only supports positive 0-10v for motion one way between both M3 and M4 commands. Are there any plans to support negative 0-10v for M4 commands to spin in reverse? The main use of this would be for tapping, if/when it's added. Side note, is 100PPM for the encoder a high enough resolution to tap with? The guys at DMM are making me a special program to get me to 96PPM with my encoder, since the resolution by default is much higher. It will at least be nice to see my RPM in real time.

Interesting,
a double pole double throw relay with the normally open and normally closed terminals swapped for the reverse would work triggered by the M4 command and the M3 command triggers a double throw single pole throw relay situated before the double pole would just open and close the signal in to the former relay... I think that would work but my head is about to explode without trying to draw it....
@steelcogs you dont need to use the 10v +/- signals, its one of the option the motor manufacturers provide. You can set the DMM mode to take 0-10v as RPM and two input signals for forward and reverse direction, then this will work directly with MASSO.
@masso-support I assume you mean spindle pins 4-7? Or did you mean 2-3? Pages 11-14 in this PDF list the DYN4's inputs. It would make sense to use pins 4-7 since the DYN4 accepts CW+/CW- (Pins 11/23) and CCW+/CCW- (Pins 10/22) but the Masso documentation doesn't list polarity for 4-7 whereas the DMM manual shows polarity.
Side question. I noticed the 0-10v idles at 0.02v which has my spindle spin very slowly when not in use. I think I had a similar issue with my CNC router using Arduino to control a VFD spindle and if I remember correctly I used a cap to clean it up. Would the same apply here, or is there something different I should do?
