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 1-00 Configuration Mode.
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 1-00 Configuration Mode.
For both positive and negative values (both
directions, relative to parameter 4-10 Motor Speed
Direction).
Function:
Select the unit to be used in process PID control
references and feedbacks. Parameter 1-00 Configu-
ration Mode must be either [3] Process or [8]
Extended PID Control.

Function:
[-999999.999 - Enter the minimum reference. The

ReferenceFeed- value obtainable by summing all
backUnit] references.
Minimum reference is active only
when parameter 3-00 Reference
Range is set to [0] Min.- Max.
The minimum reference unit
matches:
•
The configuration of
parameter 1-00 Configu-
ration Mode: for [1]
Speed closed loop, RPM;
for [2] Torque, Nm.
•
The unit selected in
parameter 3-01 Reference/
Feedback Unit.
If option [10] Synchronization is
selected in parameter 1-00 Config-
uration Mode, this parameter
defines the maximum speed
