Adjustable Speed Drive Installation and Operation Manual

H9 ASD Installation and Operation Manual 141
Automatic Light-Load High-Speed Operation Frequency
Program ⇒ Special ⇒ Crane/Hoist Settings
This parameter establishes the speed to which the ASD will ramp when
operating in the Light-Load High-Speed mode.
Direct Access Number — F330
Parameter Type — Numerical
Factory Default — 60.00
Changeable During Run — No
Minimum — 30.00
Maximum — Upper Limit (F012)
Units — Hz
Light-Load High-Speed Operation Switching Lower-Limit
Frequency
Program ⇒ Special ⇒ Crane/Hoist Settings
This parameter sets an output frequency threshold that, once surpassed, allows
the Light-Load High-Speed function to be used.
The Light-Load High-Speed function may be used if the frequency threshold
set at this parameter and the following conditions are met:
1) Light-Load High-Speed Operation Enable is configured at F328.
2) The output torque is less than the setting established in F335 when reaching
the frequency setting here.
Direct Access Number — F331
Parameter Type — Numerical
Factory Default — 40.00
Changeable During Run — Ye s
Minimum — 30.0
Maximum — Upper Limit (F012)
Units — Hz
Light-Load High-Speed Operation Load Wait Time
Program ⇒ Special ⇒ Crane/Hoist Settings
After the time setting of F333 times out, this parameter determines the length of
time that the Light-Load High-Speed criteria must be met until the Light-
Load High-Speed function engages.
Direct Access Number — F332
Parameter Type — Numerical
Factory Default — 0.5
Changeable During Run — Ye s
Minimum — 0.0
Maximum — 10.0
Units — Seconds
Light-Load High-Speed Operation Detection Time
Program ⇒ Special ⇒ Crane/Hoist Settings
This parameter determines the length of time that the load requirement must
meet the Light-Load High-Speed criteria before the Light-Load High-Speed
Enable (
F328) is recognized.
Once recognized, the timer setting of F332 must expire to engage the Light-
Load High-Speed function.
Direct Access Number — F333
Parameter Type — Numerical
Factory Default — 1.0
Changeable During Run — Ye s
Minimum — 0.0
Maximum — 10.0
Units — Seconds
Light-Load High-Speed Operation Heavy-Load Detection
Time
Program ⇒ Special ⇒ Crane/Hoist Settings
While operating in the Light-Load High-Speed mode, this parameter
determines the length of time that a load exceeding the Light-Load High-
Speed operation criteria may exist before the Light-Load High-Speed mode is
terminated and normal operation resumes.
Direct Access Number — F334
Parameter Type — Numerical
Factory Default — 0.5
Changeable During Run — Ye s
Minimum — 0.0
Maximum — 10.0
Units — Seconds
