Function:
Enter the minimum reference. The
minimum reference is the lowest
value obtainable by summing all
references.
Minimum reference is active only
when 3-00 Reference Range is set to
[0] Min.- Max.
The minimum reference unit
matches:
•
The configuration of
1-00 Configuration Mode
Configuration Mode: for [1]
Speed closed loop, RPM; for
[2] Torque, Nm.
•
The unit selected in
3-01 Reference/Feedback
Unit.
Function:
Enter the Maximum Reference. The
Maximum Reference is the highest
value obtainable by summing all
references.
The Maximum Reference unit
matches:
•
The choice of configu-
ration in
1-00 Configuration Mode:
for [1] Speed closed loop,
RPM; for [2] Torque, Nm.
•
The unit selected in
3-00 Reference Range.
Function:
Select the reference input to be used
for the first reference signal.
