Need Help! Two motos on same axis - CNCzone.com-The Largest Machinist Community on the net!

Hi,

Because of excessive flex between the two X axis gantry sides I'v decided that installing a motor on the other side is the only way to overcome the problem.

The trouble is that the second motor needs to rotate the opposite way to the first. If I'm using the same output channel from the driver for both motors is it just a case of swapping the wires on one to reverse the polarity?

The motors are Astrosyn MY103H702 and the driver is a TB6560 3 Axis powered by a 24V 10 amp power supply.

Any suggestions would be gratefully received.

Rob.

So.. where is the problem?!
You could always change (A with A') OR (B with B') phases on the motor, to make-it rotate on the opposite way

That will work. You could also just reverse the motor in your CNC software, like Mach 3.

Btw, I'd sooner reverse the wiring. I was just throwing the software option out there.

If "I'm using the same output channel from the driver for both motors" (as stated on the first post), then reversing wires is the only option.

oops. I guess I missed that.

Sorry

Thanks guys, I thought as much but just wanted to check before damaging a motor!!
