Re: Wiring diagram for UC400ETH with HDBB2

I was running them on a 42v switched mode power supply, and the stepper motors were 4.2a, i admit it was not the best setup (mine were chinese knockoffs.... i started cheap ..... and bought twice....)
I switched to leadshine am882h drives (no longer manufactured now). You can feed them up to 80v ac as they have rectifiers and capacitors in them and are rated at 8.2a, i run them direct with 50v ac feeding 4.2a drives so they have good margin, i am pushing my motors a little voltage wise but they have been fine.
Motor speed is a function of voltage.... higher the supply voltage (to a point) faster the drives can be driven relative to the same setup with a lower supply voltage.
It depends what you want to run and how fast it really needs to move and accelerate.
