Re: Mystery driver and motor

Further to my previous post I think I worked out what some of the
connection points on the Driver mean. I found a drive made by Mycom
which has the similiar marking
"CW" means clockwise
"CCW" of course means counter clockwise.
"HEAT" is a warning when the temperature on the heat sink gets to
high.
"CO+" or "CO-" this is current off/on
"C.Adj" is the current adjustment for the motor.
"CC.Adj" Current cut-off adjustment

There is still a switch on the driver to switch between "G" and "B"
which I havent worked out.
