text: <s>[INST] PF70 speed command Is it possible to use analog input 1 as the main speed command for a PF70 with analog input 2 as a trim.ie multiply the required speed of analog 1 by the % of analog 2.For example if analog 1 is 12 mA (4-20mA input) then this is half speed.Then if analog 2 is 2.5V (0-10V input) then the speed of the drive will be 50% x 25% = 12.5% The manual is very unclear.Regards Alan [/INST] I'm agree, User manual isn't so exaustive...:smileymad: Something better in the Reference Manual, did you see it ? (pages 99 - 100) Anyway, the Trim value can only be Added or Subtracted to the main reference... Hope this helps… - fuzzy logic \\n </s>
