215 Preset reference 1 (PRESET REF. 1)
216 Preset reference 2 (PRESET REF. 2)
217 Preset reference 3 (PRESET REF. 3)
218 Preset reference 4 (PRESET REF. 4)
Value:
-100.00 % - +100.00 % ✭
0.00%
of the reference range/external reference
Function:
Four different preset references can be programmed
in parameters 215-218.
The preset reference is stated as a percentage of
the value Ref
MAX
or as a percentage of the other
external references, depending on the choice made in
parameter 214. If a Ref
MIN
≠
0 has been programmed,
the preset reference as a percentage will be calculated
on the basis of the difference between Ref
MAX
and
Ref
MIN
, following which the value is added to Ref
MIN
.
Description of choice:
Set the fixed reference(s) that is/are to be obtained.
To use the fixed references, it is necessary to
have selected Preset ref. enable on terminal
16, 17, 29, 32 or 33.
Choices between fixed references can be
made by activating terminal 16, 17, 29, 32 or
33 - see the table below.

219 Catch up/slow down value
(CATCH UP/SLW DWN)
Value:
0.00-100% of the current reference
✭
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
16, 29 or 32 (parameters 300, 305 and 306), the
percentage (relative) value selected in parameter
219 will be added to the total reference.
If Slow down has been selected via one of the terminals
17, 29 or 33 (parameters 301, 305 and 307), the
percentage (relative) value selected in parameter 219
will be deducted from the total reference.
221 Torque limit for motor mode
(TORQ LIMIT MOTOR)
Value:
0.0 % - xxx.x % of T
M,N
✭
160 % of T
M,N
The max. torque depends on the unit, the selected
motor size and parameters.
Function:
This parameter sets the torque limit for motor operation.
The torque limiter is active in the speed range up to
the rated motor speed (parameter 106).
