Mm420

Hi ,

Is there a Jumper on the MM420 drive to change the Analog input from 0-10V to 4 - 20ma.?

The MM420 is designed to take only a 0-10v Input, the MM430 and 440 have inbuilt features for configuring inputs.

All is however not lost as you can buy third party convertors.

Take a look a pheonix contacts they supply a good range.

Just install a 500 Ohms resistor across the analog input, and you will have a 2-10V converter from the 4-20mA.
