I have a new TECO FM50 1hp VFD that I will be programing to use external switching to run my Emco Maximat 10-P Mentor lathe/mill. This way I'll be able to use the forward and reverse switches on my panel. And my safety switches still work. I will use the main power switch to supply power to two VFD's, 1 for the Mill Head and 1 for the lathe.
The reason I have two VFD's is that the 220V single phase motor I bought turned out to be a 3phase motor with 2 bad sections. So had it rewound $228 and the motor cost $150.
So my power goes from the panel main switch to the VFD's. I'll have a +12V wire from the VFD that runs to the rotary switch then two wires running back to the VFD, one for forward and one for reverse. With this set up I just turn on the main switch, turn on the VFD then switch the forward/reverse to the desired direction I want to run the lathe. I have two other external connection points one I plan to use for a jog feature.
I was thinking of using the other spare connection point to switch from low power to high power wiring on the two speed motor. Now in order to use the low speed I would have to wire in two tier contact with a normally open and normally closed set of contacts as the 1 2 & 3 wires from the motor need to be joined when running high speed. And open in low speed. Will this work without affecting any of the programed settings of the FM50? Any ideas?
