Hi
Not getting any 4-20 mA signal from Danfoss VLT 5000 convertor to Analog input module.
Trying to connect it to 1746-NI16I Allen Bradley (SLC 500). All VLT parameters are correct, connected pin 45 to IN0 on Allen Bradley and pin 39 to Analog Common (DIRECT CONNECTION).
 
If I use the analog output from the VLT I use the function 0-fMAX. This function will give an output signal proportional to the output frequency range in the range 0 - fMAX (remember to set max frequency in parameter 202 )

The function 0-FMAX = 4-20 mA on terminal 45 is set by value 40 in parameter 321.

Have you tested the input on PLC with a simulator?
Just to check the PLC signal working.
