Hi,
I have two small'ish Nema 23 step motors, single stack, 4 wire configuration, 1A rated, at 5V. I want to drive an X axis with two motors, same model and specification.
The single drive I have is a leadshine, 2M415, 1.5A max drive, powered by 24V DC. Microstepping, currently at 64steps but might reduce since lead is very small to probably 16steps.
The machine is to inspect PCB's so there is no tool and it is very light, no real loading, lead screw, gantry design.
I can see only two routes forward as I cannot add an additional drive,
1). Parallel them up on the single drive and set the current to 1.5A output, enough to drive both motors at 75% rated current, full 24V.
2). Serial them with the single drive, current set at 1A output, accepting the drive voltage loss of basically half, i.e. 12V.
What would you do? Which wiring would you choose and why?
I feel more pushed to the parallel option, obviously if one motor dies, the other single motor will be over driven but in that situation a lot worse things will happen since one leadscrew will turn and the other not so I doubt this situation will be prolonged (i.e. Bad noise, oh crap, panic and E-Stop pushed).
Regards,
