414 Minimum feedback
(MIN. FEEDBACK)
Value:
-100,000.000 - Max. feedback
0.000
Function:
Parameters 414 and 415 are used to scale the display
text to make it show the feedback signal as the actual
unit proportional to the signal on the input. This value
will be displayed if Feedback [unit] [3] has been selec-
ted in one of parameters 009-012 and in the display
mode. Choose the feedback signal unit in parameter
416.
Used together with
Speed control, closed-loop; Proc-
ess control, closed-loop and Torque control speed
feedback , (parameter 100).
Description of choice:
Is only active when parameter 203 has been set to
Min-Max [0].
Set the value to be shown on the display when Mini-
mum feedback is obtained on the selected feedback
input (parameter 308 or 314).
The minimum value can be limited by the choice of
configuration (parameter 100) and reference/feedback
range (parameter 203).
If
Speed control, closed-loop [1] has been selected in
parameter 100, minimum feedback cannot be set un-
der 0.
415 Maximum feedback
(MAX. FEEDBACK)
Value:
Min. feedback - 100,000.000
1,500.000
Function:
This value should be 10% higher than par. 205 Maxi-
mum reference , to keep the adjustable frequency drive
from integrating as a response to a possible offset
fault.
For further description, see parameter 414.
Description of choice:
Set the value to be shown on the display when Maxi-
mum feedback is obtained on the selected feedback
input (parameter 308 or 314) . The maximum value can
be limited by the choice of configuration (parameter
100).
