Hoist drive 

3-phase 380V/415V(±20%), 4.0~280kW 

EM630 is a close-loop vector control inverter specially designed for lift control of various kinds of cranes such as travelling crane and builder lift, etc. When applied to tower crane, it can control the 3 parts of the system respectively like hoist, trolley and slewing.

1.Salient features
 

①.   150% rated torque / 0Hz (FVC),the crane operates stably when starting, hoist and fall.

②.   Encoder feedback provides further protection: the load is hold in the air or going down slowly in case of brake failure or over speed, without slip.

③.   Unique brake control logic prolongs the service life of the brake system, and enhances the operation safety.

④.   Strong adaptability of power grid, high torque output remains when under voltage.

⑤.   Flexible and efficient operation: Light load at high speed and heavy load at low speed.
