Iīm not 100% sure wether I can use the drivers or not.
At their current condition they are pretty much useless,
current limit shuts down entire circuit and locks the motor.
(Brake is controlled with the same board) Turning power off and back on again restores the drive. There doesnīt seem to be a way to reset the board with power on..
Aboat the motors, These BG63 x 55Sīs have four pins dedicated to phase coils, A,B,C and D. Coils seem to be between A-C and B-D. Other combinations, like A-B, B-D arenīt connected. Also, the drivers I have seem to contain two H-bridges, like the datasheet says: "Electronic commutation is executed by means of bipolar selection of the 4-phase-motor winding by employing 8 transistors in the output stage."
What kind of output transistor (FET) arrangement your drivers have?
Maybe this is just us talking aboat the same thing using different terms..
I called to local PMD corporation reseller.. Good devices but a bit too expensive for me.. ~150 / axis
At that cost I think I can spend some time and make the drivers myself, even if that requires for me to learn a lot of new things.. Thatīs no problem, because projects like this tend to be also for educative purposes.
