4.4.2. 3-0* Reference Limits
Parameters for setting the reference unit, limits and ranges.
3-00 Reference Range
Option:
* Min - Max
[0]
[1] -Max - +Max
3-02 Minimum Reference
Range:
*
0.00 [-4999 - 4999]
3-03 Maximum Reference
Range:
*
50.00 [-4999 - 4999]

[0.00]
Function:
Select the range of reference and feedback signals. Values can be both positive and negative, unless par. 1-00,
Configuration Mode, is set to Process Closed Loop [3]. In that case only positive values are allowed.
Reference setpoint ranges can have positive values only.
Select this if running in Process Closed Loop.
Ranges can have both positive and negative values.
Function:
Enter value for minimum reference.
The sum of all internal and external references are clamped (limited) to the minimum reference value, par. 3-02.
Function:
Maximum Reference is adjustable in the range Minimum Reference - 4999.
Enter value for Maximum Reference.
The sum of all internal and external references are clamped (limited) to the maximum reference value, par. 3-03.
Function:
Each parameter set-up contains 8 preset references which are selectable via 3 digital inputs or bus.

Table 4.1: Par. 5-1* selection [16], [17] and [18]
Enter the different preset references using array programming.
Normally, 100% = value set in par. 3-03, Maximum Reference.
However, there are exceptions if par. 3-00 is set to Min - Max, [0].
