ABB ACS880-104

Parameters 433
79.28 Underload curve
scale coef
Defines multiplier coefficient applied to the underload limit
calculated out of the underload curve.
1.000
-30.000...30.000 Underload curve scale coef. 100 = 1
79.29 Underload curve
offset
Defines offset additive value applied to the underload limit
calculated out of the underload curve.
0.00
-30000.00...
30000.00
Underload curve offset. 10 = 1
79.31 Recovery speed
boost
Defines speed reference change in percent relative to the
production speed used at the moment when underload
condition was detected.
The new calculated speed is then used in course of the
underload recovery routine as first step in response to the
underload condition. If the value is set to 0, the speed boost
step is skipped from recovery routine.
10.00
0.00...1200.00 % Recovery speed boost. 10 = 1%
79.32 Recovery speed
drop ref
Defines absolute speed reference used in course of the
underload recovery routine as a second step after recovery
speed boost.
If the value is set to 0, the speed drop step is skipped from
recovery routine.
25.00
0.00...600.00 Hz Recovery speed drop reference. 10 = 1Hz
79.33 Recovery cycle
time
Defines time for a single recovery routine step.
The recovery speed reference change will be active for the
period of time set in this parameter.
60.0
0.0...30000.0 s Recovery cycle time in seconds. 10 = 1s
79.35 Recovery acc time Defines acceleration time setting used when URT recovery
sequence is active.
30.00
0.00...30000.00 s Recovery acceleration time. 1 = 1s
79.36 Recovery dec time Defines deceleration time setting used when URT recovery
sequence is active.
30.00
0.00...30000.00 s Recovery deceleration time. 1 = 1s
79.37 Recovery attempt
limit
Defines the number of underload ride through recovery
attempts.
1
1...100 Recovery attempt limit. 1 = 1
79.40 Overload protection
enable
Defines source for overload protection enable signal.
For further information, see Overload recovery sequence
(page 56).
