Description
Determines the amount of speed correction the PI regulator is allowed
to add. The value entered is scaled 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
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 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.
Setting range.
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
expected machine orientation.
Regulator output is not reversed. Default for winder macro.
Regulator output is reversed. Default for unwind macro.
Digital input DI2 = 1 reverses the regulator output.
