140 GX9 ASD Installation and Operation Manual
Heavy-Load Torque During Reverse Acceleration
Program Special Crane/Hoist Load
During reverse 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 — F339
Parameter Type — Numerical
Factory Default — (ASD-Dependent)
Changeable During Run — Yes
Minimum — 0
Maximum — 250
Units — %
Heavy-Load Torque During Deceleration in the Reverse
Direction
Program Special Crane/Hoist Load
During reverse 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.
