ma to hz

[ptonsparky]

PF 70e.
I'm supplying the drive with 0-20 ma.
8 should = 30 hz if vfd set for 4-20

10ma=30 hz if set for vfd set for 0-20

81 & 82 equal 0&60
91 & 92 eqaul 60&0

My drive does not give me either at the given Input.
About 80%. ?
Which parameter am I missing?
Why is available network always furthest from project?

If it's 4 - 20 mA, zero is 0 - 4 mA. The span of the range is 16 mA. Half the range is 8 mA, added to the threshold value of 4 mA, 8 + 4 is 12 mA should indicate half of the range or 30Hz. Not sure if that's what you wanted..

It helps if you set the parameters for analog input 2, instead of 1, if you're using 2.

there is no help for me today.:rant::dunce:

:thumbsup: the best kind of problems are those which involve checking the wrong box!
