Enter up to eight different preset references
(0-7) in this parameter, using array
programming. The preset reference is stated
as a percentage of the value Ref
MAX
) If a Ref
MIN
different from 0 (
) is
programmed, the preset reference is
calculated as a percentage of the full
reference range, i.e. 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
ref. bit 0/1/2 [16], [17] or [18] for the
corresponding digital inputs in parameter
group 5-1*.

Enter a percentage (relative) value to be
either added to or deducted from the actual
reference for Catch up or Slow down respec-
tively. If
Catch up
is selected via one of the
digital inputs (
5-10 Terminal 18 Digital Input
to
5-15 Terminal 33 Digital Input
), the percentage
(relative) value is added to the total reference.
If
Slow down
is selected via one of the digital
inputs (
5-10 Terminal 18 Digital Input
to
5-15 Terminal 33 Digital Input
), the percentage
(relative) value is deducted from the total
reference. Obtain extended functionality with
the DigiPot function. See parameter group
