Swift-Lift™ & Ultra-Lift™
Swift-Lift/Ultra-Lift provides additional productivity by allowing a crane or hoist to quickly move into
position. The feature enables the motor to spin faster than the base speed when the load is less than
100% of the rated capacity. Ultra-Lift determines the torque required for the load, calculates the
maximum safe speed, and automatically accelerates to this speed. The maximum speed cannot
exceed the lesser value of the Maximum Forward Speed
(C06-02), Maximum Reverse Speed (C06-
03), and Maximum Frequency (E01-04).
Swift-Lift
Swift-Lift can be enabled in the Standard Hoist motion of the G+ Series 4. In the V/f control method,
the Swift-Lift function uses motor current to determine the maximum safe speed. When the OLV
control method is selected, the Swift-Lift function uses motor torque in place of motor current for its
safe speed calculations. Swift-Lift will not be enabled if the current or torque levels exceed C06-04 or
C06-05 settings. Both C06-04 and C06-05 are a percentage of E02-01.
Ultra-Lift
Ultra-Lift can be enabled in the Non-mechanical Load Brake (NLB) Hoist motion of the VG+ Series 4
(FLV only). The Ultra-Lift function measures motor torque at base speed and then accelerates to the
maximum safe speed. Ultra-Lift will not be enabled if the torque levels exceed C06-04 or C06-05
settings.
Adaptive Ultra-Lift
Adaptive Ultra-Lift can only be enabled in the (NLB) Hoist motion of the VG+ Series 4. The Adaptive
Ultra-Lift function continuously monitors motor torque when running above base speed to increase
or decrease motor speed based on varying load conditions.
NOTE: Ultra-Lift is disabled when in traverse applications. Maximum Frequency (E01-04) must be
> C06-02 and C06-03.
