Parameter Description

3.5 Parameters: 3-** Reference/Ramps

3.5.1 3-0* Reference Limits
3-02 Minimum Reference
Range: Function:
Size [ -999999.999 - Enter the minimum reference. The
related par. 3-03 minimum reference is the lowest
*
ReferenceFeed- value obtainable by summing all
backUnit] references. The minimum reference
value and unit match the configu-
ration made in
parameter 1-00 Configuration Mode
and parameter 20-12 Reference/
Feedback Unit.
NOTICE
This parameter is used in open
loop only.
3-03 Maximum Reference
Range: Function:
Size [ par. 3-02 - Enter the maximum reference. The
related 999999.999 maximum reference is the highest
*
ReferenceFeed- value obtainable by summing all
backUnit] references.
The maximum reference unit
matches the configuration selected
in parameter 1-00 Configuration
Mode: For [1] Speed closed loop,
RPM; for [2] Torque, Nm.
If [9] Positioning is selected in
parameter 1-00 Configuration Mode,
this parameter defines the default
speed for positioning.
