Rockwell Automation 1395 Digital Reference Adapter for RTP Applications - Manual (Page 57)

Publication 1395-RTP-5.2 - September 1997
Parameter Table 8-15
Parameter 566 – [A > Velocity KP High – Speed Loop KP High
Speed]
Use: Specifies the value of KP, (Par. 660).
Program Terminal Units: None
Maximum Value: 1600
Minimum Value: 300
Default Value: 425
Description: This parameter specifies the value of proportional gain
of the velocity loop for speeds above the switch point in RPM as
determined by Parameter 569.
Parameter 567 – [A> P/I Regulator Integral Gain]
Use: Determines the proper integral gain of the digital reference
regulator.
Program Terminal Units: None
Maximum Value: 100
Minimum Value: 0
Default Value: 50
Description: This parameter specifies the value of integral gain for
the regulator in the Digital Reference Adapter Board. This integral
gain is the term which through its range of activity maintains the
dancer in the level position throughout the build down of the unwind
roll.
Parameter 568 – [A > P/I Regulator Proportional Gain]
Use: Determines the proper proportional gain of the digital reference
regulator.
Program Terminal Units: None
Maximum Value: 350
Minimum Value: 100
Default Value: 275
Description: This parameter specifies the value of proportional gain
for the regulator in the Digital Reference Adapter Board.
Parameter 569– [A> VP KI/KP Switch RPM – Press Speed VP
Switch]
Use: Specifies switch point for KI/KP of VP.
Program Terminal Units: RPM
Maximum Value: 100
Minimum Value: 20
Default Value: 30
Description: This parameter specifies the point in RPM of the belt
motor, where the integral and proportional gains of the velocity loop
will switch from the low settings as determined by Parameters 563
and 565, to the high settings as determined by Parameters 564 and
566. This is accomplished by the use of indirect Parameters 165 and
166.
