Preface
Thank you for choosing Goodrive270 series variable-frequency drive (VFD).
If not otherwise specified, the VFD in the manual always indicates Goodrive270 series VFD, which is
an optimized VFD special for fan and pump. Simple and easy to use, the VFD can drive the fans and
pumps in wastewater treatment, HVAC, chemical, metallurgical, electric power and other industries.
Using advanced vector control technologies, the VFD can drive both synchronous motors (SMs) and
asynchronous motors (AMs) in various complex work conditions. In addition, the VFD has been
embedded with various fan and pump application macros, such as PID, multi-pump control, constant
pressure water supply, effectively relieving engineers from the difficulty in debugging. The VFD uses
an independent air duct design and thickened circuit board coating, helping to adapt to hostile
environments, ensuring long and reliable run, and reducingmaintenance cost. The VFD also supports
communication bus add-on, such as CAN bus and PROFINET bus, providing better industrial control
system compatibility. The VFD power density is improved, facilitating the in-cabinet design and
reducing customer system costs. The VFD circuit optimization design has excellent electromagnetic
compatibility characteristics to ensure stable run in complex electromagnetic environments.
This manual instructs you how to install, wire, set parameters for, diagnose and remove faults for, and
maintain the VFD, and also lists related precautions. Before installing the VFD, read through this
manual carefully to ensure the proper installation and running with the excellent performance and
powerful functions into full play.
The manual is subject to change without prior notice.
