Thread: wiring help
Have finaaly started gathering every thing to start my first build and have the following electronics-
3 X Stepper motors - 3Nm, double shaft (low inductance) (M60STH88-3008DF)
3 X Microstepping Drives - 50VDC, 4.2A (MSD542)
2 X Non-regulated power supplies - 40V, 7A (PS407)
1 X Breakout board
Is the best way to wire this to follow the pdf on this link
You will want the motors in bipolar parallel to get higher torque at high speed.
There's the information you need to do it in the PM752 driver datasheet:
You will want the stepper motor's datasheet to find out which colour wire is which:
That driver is connected the same as yours, the only difference is setting the current. You set the current with the switches on the side of the driver using the table printed on the driver casing. With the motors in Bipolar Parallel you will want the driver set at 4.2A.
Two options with the power supplies, either connect one of the power supplies to two drivers, and the other one to one driver. Or, if it is safe to do so, connect the power supplies in parallel, then connect that to all the drivers. The diagram you linked to has the power supplies in parallel so I would assume that is permissible.
Let me know if there's anything I've missed...
