Mitsubishi D700 Inverter
Mitsubishi D700 Inverter
(OP)
Hi
For some apparent reason, our production staff would like us to display the frequency the inverter is running at. The inverter is located inside a control panel so I was wondering if there was some way to connect a display unit (something like a Dixel) to the inverter which would display the frequency externaly.
Due to the nature of our business i would like to steer clear of HMI's as hygiene like to see how wet they can get them. Lol!
Any help gratefully recieved.
Kind regards
Stuart

RS485/Modbus RTU
The display you want to use does it support this interface?

Dixel makes connectors, sure you didn't mean Dixon? I don't think those come in NEMA 4, but the little Red Lion Cub 5 series does.
A cheaper and simpler all around option though would be to just put a NEMA 4 window on the enclosure door over the VFD's display.

I've just ordered 4 Red Lion units as a cheap option (£110each). Pieces per minute would be a better display but not sure if the red lion unit would be able to do that.

So by that I mean you can have the display show 0-100% of the analog signal coming into it. Then you tell the VFD that the analog output represents pieces per minute, with 100% (10V output) representing the maximum speed of the drive. Then your display gets a little nameplate above it that says "Percent of maximum PPM of 1200 Pieces" and they will have to do the math.
If you want the METER to do the math for you, be prepared to pay a lot more for the meter.
Another reason why a clear window on the door over the VFD display would be better, you CAN program the VFD display to show Parts Per Minute, albeit only the numerical value.
