As far as I know, EMC does not have any provisions for a reduce-current
signal to the drivers. If your drivers have a reduce current input, then you
need to connect that to something that will actually command the drivers
to move or hold mode. Running ALL axes at move mode setting when any
is moving might be a good idea, as the motors may need full current to
hold against cutting forces.
