I'm wondering if anyone has any experience with using a 480V 3 phase inverter and connecting it to a 230V 3 Phase motor? I have done this in the past with no problems. I now have an application where I did the same thing in order to over speed the motor and not loose any torque (V/Hz ratio) and...
Can anyone tell me excatly how a LPF instruction works in RS 5000? I have an application where we are taking a signal from a load cell and passing it through a LPF in the 5000 program. The application is a loss in weight feed system. The problem I am having is that whenever we refill the hopper...
Does anyone have an opinion on whether you should feed a load cell excitation voltage with a linear or switching power supply? I have an application where I am feeding a load cell with 10VDC excitation from a switching SOLA power supply and my raw weight signal has some variation. It seems to be...
I am having problems with some of our 1746-OA16 cards on a SLC 500 system. I am controlling solenoid valves with this card and they are 120VAC, 25 Watt each. That should put me at .20 amps per solenoid (just shy of the .25 amp rating for each point on the card).I keep having problems with some...
Does anyone know where I might be able to find a wiring schematic for a Master motor that was probably manufactured in the 40's? I have the nameplate info. It is a 440V 3 phase AC motor, but it has 14 leads. The nameplate also has ratings for 4 different speeds at 440V. This leads me to believe...
