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 —
Yes
Minimum — 30.0
Maximum — Upper-Limit (
F012
)
Units — Hz
Light-Load High-Speed Operation Load Wait 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
F333
must expire to engage the Light-
Load High-Speed function.
Direct Access Number — F332
Parameter Type —
Numerical
Factory Default —
0.5
Changeable During Run —
Yes
Minimum — 0.0
Maximum — 10.0
Units — Seconds
Light-Load High-Speed Operation Detection Time
Program
Special
Crane/Hoist Settings
After the time setting of
F332
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 — F333
Parameter Type —
Numerical
Factory Default —
1.0
Changeable During Run —
Yes
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 —
Yes
Minimum — 0.0
Maximum — 10.0
