It is Minomat and Minomat N, not the HP24. The serial number of Minomat is HP3002 and HP3004 for Minomat N. The HP3003 is for Minotact the semi-auto one.
I have one Minomat first and the main motor to drive the slide was damaged. I got my new Minomat N today and I was tested it. At the first all was well but when I try to advanced the slide fastly it suddenly lost response. I tested by multimeter and it shows that electric circuit is fine so I guess the main motor may damaged agian.
Minomat N use a 10v motor(through my measurement) so I try to get a new one and replace it.
