Light-Load High-Speed Operation Heavy-Load Detection
Time
Program Special Crane/Hoist Load
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 — 5.0
Changeable During Run — Yes
Minimum — 0.0
Maximum — 10.0
Units — Seconds
Switching Load Torque During Forward-Run
Program Special Crane/Hoist Load
While running forward, this parameter establishes the threshold torque level
that is used to determine if the Light-Load High-Speed (F331) operation may
engage or remain engaged if active.
If the Light-Load High-Speed operation is terminated normal operation
resumes.
Direct Access Number — F335
Parameter Type — Numerical
Factory Default — 50
Changeable During Run — Yes
Minimum — 0
Maximum — 250
Units — %
Heavy-Load Torque During Acceleration in the Forward
Direction
Program Special Crane/Hoist Load
During forward acceleration, this parameter establishes the threshold torque
level that is used to determine if the Light-Load High-Speed (F331) operation
may engage or remain engaged if active.
If the Light-Load High-Speed operation is terminated normal operation
resumes.
Direct Access Number — F336
Parameter Type — Numerical
Factory Default — (ASD-Dependent)
Changeable During Run — Yes
Minimum — 0
Maximum — 250
Units — %
Heavy-Load Torque During Deceleration in the Forward
Direction
Program Special Crane/Hoist Load
During forward deceleration, this parameter establishes the threshold torque
level that is used to determine if the Light-Load High-Speed (F331) operation
may engage or remain engaged if active.
If the Light-Load High-Speed operation is terminated normal operation
resumes.
Direct Access Number — F337
Parameter Type — Numerical
Factory Default — 100
Changeable During Run — Yes
Minimum — 0
Maximum — 250
Units — %
Switching Load Torque During Reverse-Run
Program Special Crane/Hoist Load
While running in reverse, this parameter establishes the threshold torque level
that is used to determine if the Light-Load High-Speed (F331) operation may
engage or remain engaged if active.
If the Light-Load High-Speed operation is terminated normal operation
resumes.
Direct Access Number — F338
