Hi Gary,

In my case, probably 2 factors.

The first was I had no DC controller for the motor, at least, not what I could see in the 2 machines I bought. There is meant to be a controller / drive in the 2nd machine's cabinet however the way the machine is placed means I cant open the cabinet and I cannot move / access the machine (long story).

The second was due to single phase only, when I ordered I had assumed that it would be a single phase drive, unfortunately some misunderstanding and it turned out to be 3 phase but I do run it from another VFD and it works, albeit that Ive needed to slow the ramp down time else I trip the feeding drive.

Thanks
