Description
Selects the activation source for forcing the integral part of the PI
controller compensation to be zero. The PI controller will become just
a P controller.
Function not selected.
Digital input DI2 = 1 forces the integration time to zero.

Determines the amount of speed correction the PI regulator is allowed
to add. The value entered is scaled to
Example:
If 62.05 Range adjust = 5%
62.06 TRIM REG REL TO = "SPD REF MAX"
11.05 EXT1 REF MAX = 1800 rpm
03.03 DANCER REG OUTPUT = 100%
65.01 MIN CORE DIAMETER is 100 mm
03.13 ROLL DIAMETER (mm) is 1000 mm
Then
25.03 SPEED CORRECTION = 0.05*1800*1*(100/1000) = 9 rpm
Setting range.
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.
Value set by 11.05 EXT1 REF MAXIMUM.
Value set by 11.03 EXT1 REF SELECT with a minimum reference for
scaling of 62.07 MIN REF TO REG.
If 62.06 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.
