The Galil card has +- analogue output so it can be reversed from the control M3 and M4 are the M codes for sp fwd & rev, M5 is spindle stop.
First method is to reverse the spindle directions in the M3 & M4.
2nd method if the spindle fwd & rev commands runs the spindle in the wrong directions you could just reverse the analogue input into the drive.
Otherwise you would have to reverse the field and tach connections.
First method is preferable.
