Switch leads at one motor????

Don't forget to switch leads appropriately at servo encoder if so equipped.

Swap motor leads on one winding only. Doesn't matter which one.

If you are using along with CNC, may exist one parameter for make the inversion at CNC.Check that. Of course this is conditioned to the CNC model.
