Hi Andre'
I was able to increase the output voltage on a 208 generator here to 240
leg to leg. I just disabled any connection to the neutral and run it
for pure three phase to motors.

Thanks for the info.
As for the 3PH transformer, I am not connected to the grid, got a PV and
wind generator setup with a battery pack and an inverter which will not run
a machine of this size for any useful length of time anyway.
Picked up a 3PH diesel generator a few years back that will run t

I think I have this information somewhere. From memory the drives
have directional disables but they are wired together because there is
only one limit switch per

I am looking at buying a BP series II R2E3. Near as I can tell so far
everything works, jogs around and runs one block commands in MDI, I could
not figure out how to punch in a complete program when I was looking at the
machine.
I was wondering if I were to convert it to EMC how much of the ex
