VFD for a 3hp 2 speed 3phase motor on a mill...will it ...
Aug 30, 2013· Then you set up motor setup #1 to not do anything and it will keep all relays open/unlatched and the motor will be setup for the slow speed range Then you setup motor setup #2 (maybe enabled by a switch?) to latch the coils and the relays will setup the motor output for the fast speed. Just typing out loud. What do you think?
