Parameter 3-10 Preset Reference
Table 178: Parameter 3-10 Preset Reference
3-10 Preset Reference
Default value: 0%
Parameter type: Range, -100 - 100%, Array [8]
Setup: All setups
Conversion index: -2
Data type: Int16
Change during operation: True
Enter up to 8 different preset references (0–7) in this parameter, using array programming. The preset reference is stated as a per-
centage of the value Ref
MAX
(
parameter 3-03 Maximum Reference
). If a Ref
MIN
different from 0 (
parameter 3-02 Minimum Reference
) is
programmed, the preset reference is calculated as a percentage of the full reference range, that is on the basis of the difference
between Ref
MAX
and Ref
MIN
. Afterwards, the value is added to Ref
MIN
. When using preset references, select preset reference bit 0/1/2
[16], [17] or [18] for the corresponding digital inputs in
parameter group 5-1* Digital Inputs
.
