Salvaged from a copier I have a Vexta 5 phase stepper complete with the driver board.
This board works with the SLA5011 and SLA5012 drivers controlled by a thick film Hybrid EIC0241 and a plcc ic EIC0231. Because of this complex ic I hope it includes a complete sequencer so I can control the board with step, direction , enable and mode signals.
The control input connection has eleven wires, three ground and nine signal lines. I tried to find out if there are step and direction inputs among these nine lines, but it is not that simple. I find three inputs who act as a kind of enable but I cannot find a step input.
Is somebody familiar with this combination of drivers ? On the net I cannot find any datasheets, so if anyone has some information about this controller I would be very happy.
