eeveland Posted April 6, 2014 Report Share Posted April 6, 2014 I wrote a program using a MI to control a 4-20mA output. I have set limits for the MI from 819 to 4095 which I believe is the range for the 4-20mA output. I connected a multimeter inline with the output while controlling a AB Powerflex 4 drive. At the top of the range the motor runs at full speed and the multimeter is showing 20mA, however at the lower end of the scale, at 819 the motor is still crawling and I'm showing an output of 7mA. Is my range incorrect or am I overlooking something? Gas Modulator.vlp Quote Link to comment Share on other sites More sharing options...
