Ultra-Lift
Ultra-Lift provides additional productivity by allowing a crane or hoist to quickly move into
position. The feature enables the motor to over speed when the load is less than 100 percent of the
rated capacity. Ultra-Lift determines the torque required for the load, calculates the maximum safe
speed, and automatically accelerates to this speed. However, the maximum speed cannot exceed the
lesser value of the Ultra-Lift Maximum Output Frequency-RAISE (C6-02), Ultra-Lift Maximum
Output Frequency-LOWER (C6-03), and Maximum Frequency (E1-04).
NOTE: Note: Ultra-Lift is disabled when in traverse applications. Maximum Frequency (E1-04)
must be >
C6-02 and C6-03.
