140 H9 ASD Installation and Operation Manual
Drooping Insensitive Torque
Program Feedback Drooping Control
This parameter defines a torque range in which the Drooping Control settings
will be ignored and the programmed torque settings will be followed.
Direct Access Number — F323
Parameter Type — Numerical
Factory Default — 10.00
Changeable During Run — Yes
Minimum — 0.00
Maximum — 100.0
Units — %
Drooping Output Filter
Program Feedback Drooping Control
This parameter is used to set the rate of output change allowed when operating
in the Drooping Control mode.
Jerky operation may be reduced by increasing this setting.
Direct Access Number — F324
Parameter Type — Numerical
Factory Default — 100.0
Changeable During Run — Yes
Minimum — 0.1
Maximum — 200.0
Units — Radians/Second
Light-Load High-Speed Operation
Program Special Crane/Hoist Settings
This parameter enables the Light-Load High-Speed function by selecting an
operating mode. The Light-Load High-Speed function accelerates the output
frequency of the ASD from the programmed speed to the setting established in
F330.
This parameter may be disabled.
Enabling the Light-Load High-Speed function requires that an operating mode
be selected here, and that the criteria of parameters F331 – F333 be met.
Settings:
0 — Off
1 — Auto Speed (F-Motor: Up, R-Generator:Down)
2 — Auto Speed (F-Generator: Down, R-Motor:Up)
3 — F330 Setting (F-Motor: Up, R-Generator:Down)
4 — F330 Setting (F-Generator: Down, R-Motor:Up)
Direct Access Number — F328
Parameter Type — Selection List
Factory Default — Off
Changeable During Run — Yes
Light-Load High-Speed Learning Function
Program Special Crane/Hoist Settings
The Light-Load High-Speed function accelerates the output frequency of the
ASD from the programmed speed to the setting established in F330 and is
primarily used with Crane/Hoist functions.
During Light-Load High-Speed operation with this parameter enabled,
parameters Panel Torque Bias (F343), Creep Frequency (F346), and the
Creep Time (F347) are set to a standard set of light-load profile values.
Application-specific adjustments may be required.
Note: This function should be setup with a light load only.
Settings:
0 — Off
1 — Forward/Reverse
2 — Forward Only
Direct Access Number — F329
Parameter Type — Selection List
Factory Default — Off
Changeable During Run — No
