Evening,

I currently use Rexroth VFD´s, but the scaling options are a bit sparse.
Basically it has a multiplier that you can set from 0.1 to 100.
For example on a pillar drill I added one to, I wanted the display to show RPM, but as the motor is geared down (for example 12:1), you only get two decimal places and you can't get it accurate enough.
I know I´m being anal, but is there a low cost VFD that has a multiply and divide for scaling?
Thanks.

add a display meter to the setup they can be scaled to whatever you like from a 0 to 10v input

That’s a way, I was hoping to find a reason to use a different drive this time though!
Looking at the Siemens V20 it has a multiplier and divisor but it’s so hideous to look at!
Thanks.
 
not sure of that drive but when doing initial set up and have changed the rated motor speed for something similar before.
