Viewing the status on Danfoss VFD inputs

Hello- A customer recently asked about how to view the status of the inputs on a Danfoss VFD— Are they on or off? Here is an easy way to check using the display.

Navigate to parameter 16-60 “Digital Input”

The display is binary, showing the status of all the inputs at that moment. Zero means the input is “off” and a one is “on”.

To tell which digit is for which input, you have to use the chart below from the programming guide.

Input 18 is typically used for the Start/stop, according to the chart input 18 is “Bit 5”, AND YOU COUNT FROM THE RIGHT STARTING WITH BIT 0.

In summary, input 18 is going to be the sixth zero from the right if that makes sense. See the picture below.

As always, call us if you have any questions.
