Thank you for choosing Goodrive350A series variable-frequency drive (VFD).

If not otherwise specified in this manual, the VFD always indicates Goodrive350A series VFD, which is a high-performance multifunctional VFD that can drive both synchronous motors (SMs) and asynchronous motors (AMs) and supports torque control, speed control, and position control. The VFD is armed with advanced vector control technology and the latest digital processor dedicated for motor control, thus enhancing product reliability and adaptability to the environment. The VFD adopts customized and industrialized design to realize excellent control performance through optimized functions and flexible applications.

In order to meet diversified customer demands, the VFD provides abundant expansion cards including programmable expansion card, PG card, communication card and I/O expansion card to achieve various functions as needed. Each VFD can be installed with three expansion cards at most.

The programmable expansion card adopts the mainstream development environment for customers to carry out secondary development easily, fulfilling varied customized needs and reducing customer cost.

The PG card supports a variety of encoders like incremental encoders and resolver-type encoders. In addition, it also supports pulse reference and frequency-division output. The PG card adopts digital filter technology to improve EMC performance and to realize stable transmission of the encoder signal over a long distance. It is equipped with encoder offline detection function to contain the impact of system faults.

The VFD supports multiple kinds of popular communication modes to realize complicated system solutions. It can be connected to the internet with optional wireless communication card, by which you can monitor the VFD state anywhere any time through mobile App.

The VFD uses high power density design. Some power ranges carry built-in DC reactor and braking unit to save installation space. Through overall EMC design, it can satisfy the low noise and low electromagnetic interference requirements to cope with challenging grid, temperature, humidity and dust conditions, thus greatly improving product reliability.

This operation manual presents installation wiring, parameter setup, fault diagnosis and trouble shooting, and precautions related to daily maintenance. Read through this manual carefully before installation to ensure the VFD is installed and operated in a proper manner to give full play to its excellent performance and powerful functions.

If the product is ultimately used for military affairs or manufacture of weapon, it will be listed on the export control formulated by Foreign Trade Law of the People's Republic of China. Rigorous review and necessary export formalities are needed when exported.
