stepper best practices

Here's a best-practices type question:

IF using stepper drives and a separate 48VDC power supply, is it a good idea to use a separate power supply for each drive, or is it alright to use more than one drive per supply (within amperage limits, of course)

Thanks,

TM

I would use separate power suplies

Starting on PDF page 47 of this manual:

There is a description of power supplies for stepper drives. The discussion is particular to this drive but may be a useful read as it discusses some of the issues with running multiple drives on a single supply.

One supply is fine. Use large gauge wire to insure a heavy current load from one motor doesn't induce noise in other motors. Add additional caps at drives if that becomes a problem. A good practice to insure it doesn't.
3300-4700 uF should work well for size 23 motors.
