Magnetek Quattro DC Elevator Drive Benutzerhandbuch

Any value over 100% will cause the analog 
channel to saturate.

 

With a gain of 1.0 and an offset of 0.0, 10V will 
indicate 100% or full value based on 
programmed values.  For example, with the 
above scenario of a gain of 1.0 and an offset of 
0.0, a 10V signal an Analog Output set to arm 
current would indicate 100% of rated current.  

Whereas a 0V signal on the same Analog 
Output would indicate 0% of rated current.
