63.05 RANGE ADJUST Determines the amount of speed correction the PI regulator is allowed
to add. The value entered is scaled to 63.06 TRIM REG REL TO.
Example:
If 63.05 RANGE ADJUST = 5%
63.06 TRIM REG REL TO = “SPD REF MAX”
11.05 EXT1 REF MAX = 1800 rpm
03.09 TENSION REG OUTPUT = 100%
65.01 MIN CORE DIAMETER is 100 mm
03.13 ROLL DIAMETER (mm) is 1000 mm
Then in Closed loop Speed Trim Mode
25.03 SPEED CORRECTION= 0.05*1800*1*(100/1000)= 9 rpm
0.0…100.0% Setting range. 10 = 1%
63.06 TRIM REG REL TO Setting this to “SPD REF MAX” multiplies the output of the PI regulator
by 11.05 EXT1 REF MAX. Setting it to “SPD REF ACT” multiplies the
output of the PI regulator by the actual speed reference to the drive.
Selecting “SPD REF MAX” means that the maximum speed correction
is constant, regardless of the drive speed, whereas selecting “SPD
REF ACT” gives a varying maximum that is speed dependant.
SPD REF MAX Value set by 11.05 EXT1 REF MAXIMUM. 0
SPD REF ACT Value set by 11.03 EXT1 REF SELECT with a minimum reference for
scaling of 63.07 MIN REF TO REG.

63.07 MIN REF TO REG If 63.06 TRIM REG REL TO is set to “SPD REF ACT” it may be
desired to have a minimum value that the PI regulator is multiplied by;
this minimum value is set here. If the actual speed reference goes
below this parameter, the PI regulator output will no longer be
multiplied by the reference, it will instead be multiplied by this
parameter.
0…1000 rpm Setting range. 10 = 1 rpm
63.08 REV REG OUT This is set to a default value by the program, depending on the macro
selected. If the PI regulator is adjusting the speed in the wrong
direction it can be reversed here. See 60.05 WINDING MODE for
expected machine orientation.
NO – WINDER Regulator output is not reversed. Default for winder macro. 1
YES – UNWIND Regulator output is reversed. Default for unwind macro. 2
DI2 Digital input DI2 = 1 reverses the regulator output. 3
DI3 See selection DI2. 4
DI4 See selection DI2. 5
DI5 See selection DI2. 6
DI6 See selection DI2. 7
DI7 See selection DI2. 8
DI8 See selection DI2. 9
DI9 See selection DI2. 10
DI10 See selection DI2. 11
DI11 See selection DI2. 12
DI12 See selection DI2. 13
FIELDBUS See selection DI2. Instead of a digital input, the command comes from
06.03 DATASET 1 WORD 3 bit 15. See chapter Fieldbus control.
