[1.0 -
1000.0 %]
This is a true current limit function that
continues in the oversynchronous range,
however due to field weakening the
motor torque at current limit will drop
accordingly when the voltage increase
stops above the synchronised speed of
the motor.
3.3.7 F-5# Extended References
Parameters to configure drive min/max reference and
reference function.
F-50 Reference Range
Option:
Function:
Select the range of the reference signal and the
feedback signal. Signal values can be positive
only, or positive and negative. The minimum
limit may have a negative value, unless [1] Speed
closed loop control or [3] Process is selected in
[0]
Min -

Select the range of the reference signal and the
feedback signal. Signal values can be positive
only, or positive and negative. The minimum
limit may have a negative value, unless [1] Speed
closed loop control or [3] Process is selected in
[1]

For both positive and negative values (both
directions, relative to H-08 Reverse Lock).
F-51 Reference/Feedback Unit
Option:
Function:
Select the unit to be used in Process PID Control
references and feedbacks. H-40 Configuration
Mode must be either [3] Process or [8] Extended
PID Control.

summing all references.
Minimum Reference is active
only when F-50 Reference
