EM330D is a specially designed inverter for hoisting of construction lift, and hoisting,
trolleying and slewing of tower crane. Parameter defaults vary with options of F4-28
Application Macros, please see Section 6.3 for details.
EM330D features:
Stable operation with big torque at low frequency
Stable output at 0.5Hz/150% of rated torque to ensure stable operation of cranes at
start-up, hoisting, and descending.
Special control function of brake
The brake for hoisting device control will be on/off in rational sequence. The operation
of construction lift has been smoothed greatly.
Optimum current limit
Inverter will not trip fault when the load varies frequently.
Wide voltage input range
AVR function ensures that the output can meet torque output requirments of hoisting
devices if the grid voltage drops.
Wide speed regulation range
Meeting the requirements of cranes for high speed with light load and low speed with
heavy load, enhancing the working efficiency of cranes.
It is the duty of any user to perform the appropriate, correct installation or configuration of
the optional parameters of the devices. Neither SINEE nor its distributors shall be
