Preface

Goodrive300-01A series variable-frequency drive (VFD) for air compressors (hereinafter referred to

as GD300-01A VFD) is designed and developed by INVT based on the requirements of the air

compressor industry, which can be applied in the control of synchronous/asynchronous air

compressor. The product supports an optional multi-function expansion card, which is suitable for air

compressor control that requires more functions.

Goodrive300-01A VFD carries the air compressor-specific control logic to connect to various signals

of the air compressor directly e.g. emergency-stop, pressure and temperature signals, fan current

transformer and fault signals. It can provide 24V power to HMI. It also carries RS485 communication

interface of standard Modbus protocol to fit the HMI without external controller or PLC, simplifying the

electrical design while realizing excellent variable-frequency control.

GD300-01A VFD has undergone compatibility test with multiple mainstream motor or master

manufacturers based on the application features and actual needs of air compressor industry. It

adopts dedicated PID and unique flux-weakening design to enable the air compressor to start quickly

and run smoothly with max driving frequency reaching 400Hz. Through high-power density design

and compact structure, it simplifies commissioning procedures and downgrades product size. It

adopts independent air duct, heavy-load and high power factor design to cope with challenging field

and grid environment.

Read this manual carefully before installation to ensure GD300-01A VFD can be installed and

operated correctly to give full play to its excellent performance.

If the product is ultimately used for military affairs or weapon manufacture, comply with the export

control regulations in the Foreign Trade Law of the People's Republic of China and complete related

formalities.

Our company reserves the right to update the information of our products without prior notice.
