Introduction:INVT Inverter GD20-09-004G-4-B, GD20-09 series lifting special inverter for electric hoist, European crane, small tonnage gantry or overhead crane load characteristics and control requirements research and development of lifting special open-loop vector inverter, in line with lifting industry standards, integrated lifting special functions, compact structure, excellent performance, a full range of built-in braking units, through the overall design of electromagnetic compatibility and strict reliability testing, It meets the user's environmental requirements for low noise and low electromagnetic interference in the application site, and greatly improves the reliability of the product.

INVT inverter GD20-09-004G-4-B protection grade IP20

Features:

All models are equipped with a built-in braking unit as standard

Dedicated terminal design, more diverse choices

Special brake logic: brake logic control fusion torque verification, brake release control after torque establishment is completed, safety does not slip;

The logic control of the brake supports the selection function of starting direction and forward and reverse switching, which meets various starting requirements and has good adaptability.

Application macro: Integrate a variety of lifting application macro modes and support user-defined macros, one-click debugging, and simpler application.

Conical rotor motor control: The magnetic flux is adjusted according to the characteristics of the conical rotor motor, which realizes fast brake release and brake holding control, simplifies the commissioning steps, and ensures safety.
