INVT GD20 series compact frequency converter

INVT GD20 vector frequency converter: the versatile driving choice for small and medium power industrial control scenarios

In the wave of industrial automation upgrading, small and medium power drive scenarios have put forward more stringent requirements for the performance, size, and usability of frequency converters. The Goodrive20 (GD20) series vector frequency converter from Envision, with its speed sensorless vector control core technology, has become the preferred solution for many small and medium power industrial control applications such as food machinery, plastic machinery, textile equipment, and conveyor systems due to its excellent driving performance, flexible adaptability, and high reliability.

The core competitiveness of the GD20 series comes first and foremost from its ultimate control performance. The product adopts PG free vector control method and supports self-learning of parameters for both rotating and stationary dual-mode motors. It can meet the self-learning needs of off load rotation in high-precision control scenarios, and also solve the on-site debugging problem of motors unable to disconnect from loads, achieving higher control accuracy and faster response speed. Whether it is a 0.5Hz low-frequency full load condition or a 400Hz high-frequency steady-state operation, the product can maintain excellent current control performance, coupled with overvoltage/overcurrent stall suppression and multiple braking methods, greatly reducing the probability of fault shutdown and ensuring continuous and stable operation of the equipment.

In terms of structural design and hardware configuration, the GD20 series is also full of highlights. 380V 2.2kW and below models adopt a mini design, supporting parallel installation of multiple machines, greatly saving control cabinet space; The independent air duct design effectively enhances equipment protection capabilities and adapts to complex and harsh industrial site environments. The product comes standard with a built-in 485 communication interface, 18.5-110kW models come standard with a built-in DC reactor, and 37kW and below models come standard with a built-in braking unit. The rich hardware configuration does not require additional accessories, which can meet the vast majority of on-site application needs and reduce customers' comprehensive usage costs.

From flexible installation methods to powerful software functions, from comprehensive protection mechanisms to comprehensive service systems, the GD20 vector frequency converter provides a cost-effective and reliable solution for small and medium power industrial drive scenarios with its versatile product performance, helping industrial control equipment achieve more efficient and stable automation operation.
