Hi Peter B,
We are working on a very old Mkino Copy milling machine.
It is using similar 5 phase pulse motor model EPM-109 by FUJITSU_FANUC.
We are making its driver circuit to be used with step and direction signals.
We will let you know as soon as its ready.
Regards
Nasir Karachi Pakistan.

Gday peter!
How many you got/want to get rid of? how much you want for em?
We want to drive Fanuc EHPMs ("electro-hydraulic pulse motors") which are
classic 5-phase+common wiring.
