technology controller fixed value

Hi Expert,

I only have one question about fixed speed setpoint. Can we use signal 4-20ma for fixed setpoint?

Example: 100% = 20ma = 50hz

                 90% = 18.4ma = 45hz

* At 18.4ma the frequency is 45hz and 20ma is 50hz. What I want is if when I give signal for example 18.5ma - 19.99ma  the frequency still at 45hz. The frequency will only turn to 50hz when the signal reach at 20ma. Can we do that? I need to play at 10hz, 20hz, 30hz, 40hz and 50hz fixed but control by 4-20ma.

Thanks in Advance.

Hello,

which drive do you use? (G120, S120,...)

this could be done with free blocks (if available in your drive) or with DCC (Sinamics S120)
