Parameter Descriptions
F-43 Current Limit
Range: Function:
160.0 % [1.0 - This is a true current limit function that
1000.0 %] 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 synchronized 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
parameter H-40 Configuration Mode.
[0] Min - Select the range of the reference signal and the
Max 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
parameter H-40 Configuration Mode.
[1] -Max - For both positive and negative values (both
+Max directions, relative to parameter H-08 Reverse Lock).
*
F-51 Reference/Feedback Unit
Option: Function:
Select the unit to be used in process PID control
references and feedbacks. Parameter H-40 Configu-
ration Mode must be either [3] Process or [8]
Extended PID Control.

F-52 Minimum Reference
Enter the minimum reference. The minimum reference is the
lowest value obtainable by summing all references.
Minimum reference is active only when parameter F-50 Reference
Range is set to [0] Min.- Max.
