3 of my 4 Dyn2 servo drives seem to be randomly losing the odd setting here and there on startup.
One drive which was running fine switched from step/direction mode to cw/ccw upon a reboot and another reset it's main gain from 65 to 1 on a reboot.
These drives are working fine and once I use DMMDrv to change the settings back they continue to work fine.

I have contacted DMM about this but have yet to receive a reply.

Has anyone seen this behaviour before?
