215 Preset reference 1 (PRESET REF. 1)
216 Preset reference 2 (PRESET REF. 2)
Settings:
-100.00 % - +100.00 %
% of the reference range/external reference
0.00%
Function:
Two different preset references can be programmed
in parameters 215-216.
The preset reference is stated as a percentage of
the value Ref or as a percentage of the other
MAX
external references, depending on the choice made
in parameter 214. If a Ref
programmed, the preset reference as a percentage
will be calculated on the basis of the difference
between Ref and Ref
MAX MIN
value is added to Ref .
MIN
Description of choice:
Set the fixed reference(s) that is/are to be the
options.
To use the fixed references, it is necessary to have
selected Preset ref. enable on terminal 2, 3, 4, or 5
(parameters 332 - 335).
Choices between fixed references can be made by
activating terminal 2, 3, 4, or 5 - see the table
below.

219 Catch up/slow down value
(CATCH UP/SLW DWN)
Settings:
0.00 - 100.00 %
0.00 %
Function:
This parameter enables the entry of a percentage
value (relative) which will either be added to or
deducted from the actual reference.
Description of choice:
If Catch up has been selected via one of the
terminals 2, 3, 4, or 5 (parameters 332 - 335), the
percentage (relative) value selected in parameter
219 will be added to the total reference.

221 Current limit for motor mode
(CURRENT LIMIT)
Settings:
Min. limit (XX.X) - max. limit (XXX.X)

Max. limit (XXX.X)
I = rated motor current
RATED
Min. limit = magnetizing current in % of I
Max. limit = unit dependent limit in % of I
Function:
This function is relevant for all application
configurations; speed and process regulation. This is
where to set the current limit for motor operation.
