Hi,
I am retrofitting a Shizouka cnc knee mill with a Bandit controller
which has some 6 wire steppers on it and I am trying to figure out
whether I should wire them in full or half winding. The drives that
were on there have inputs for A1, A2, Acommon, B1, B2, Bcommon, so I
can't tell from the previous wiring scheme. I have 203V's. Looking at
the schematic for the old drives, for each winding, there is a diode
between the common and each side of the winding. The diagram shows
the diode inside a dotted line rectangle with a transistor as well.
The rated amperage on the motors is 3.1 and the rated voltage is 4.5 (I
think). The power supply on the machine is 45 Volts.
Any ideas?
Thanks,
Bill
