FCM Series
If External/preset [2] is selected, it is possible to shift
between external references or preset references
via terminal 2, 3, 4, or 5 (parameter 332, 333, 334,
or 335). Preset references will be a percentage
value of the reference range.
External reference is the sum of the analogue
references, pulses and bus references.
NB!:
If Sum is selected, one of the preset references
will always be active. If the preset references
are to be without influence, they should be
set to 0 % (as in the factory setting).
215 Preset reference 1
(PRESET REF. 1)
216 Preset reference 2
(PRESET REF. 2)
Value:
-100.00 % - +100.00 %
[-10000 - +10000]
% of the reference range/external reference
0.00%
[0]
Function:
Two different preset references can be programmed
in parameters 215-216.
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 the 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 be
low.
Terminals 2/3/4/5
Preset reference
Preset reference 1 0
Preset reference 2 1
NB!:
The parameter 215-216 setting automatically
will be the setting of parameter 241-242
as well. Parameter 241-247 can be used
for up to 7 preset references.
219 Catch up/slow down value
(CATCH UP/SLW DWN)
Value:
0.00 - 100.00 %
[0 - 10000]
✭0.00 %
[0]
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.
If Slow down 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 deducted from the total reference.
221 Current limit for motor mode
(CURRENT LIMIT)
Value:
Min. limit (XX.X) - max. limit (XXX.X)
in % of I
RATED
[XXX - XXXX]
✭Max. limit (XXX.X)
[XXXX]
I
RATED
= rated motor current
Min. limit = magnetising current in % of I
RATED
Max. limit = unit dependent limit in % of I
RATED
Function:
This function is relevant for all application configurations;
speed and process regulation. This is where to set
the current limit for motor operation.
✭
= factory setting. () = display text [] = value for use in communication via serial communication port
