I went through so much with DMM, they even sent me a new DYN4 drive with software changes to fix my "issues" they couldnt tell me what was changed or why they were sending me another unit. This one also does not work. I have tried different encoders, re-calibrating encoders, have tested wiring, motor amperage draw, mains power amperage draw, adding and removing all filters, every calibration setting in the dyn4 software, took the whole assembly to a different location for different power.

The motor will run in torque mode to 3000rpm no worries, step/dir or speed mode, dies at about 2500rpm.

I regret buying DMM equipment.
