TD350 Series VFD Preface
Preface
Thank you for choosing TD350 series variable-frequency drive (VFD).
TD350 is a high-performance and multi-function VFD aiming to integrate the synchronous motor drive
with asynchronous motor drive, torque control and speed control with position control. It 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. TD350 series VFD adopts
customized and industrialized design to provide excellent control performance through optimized
functions and flexible applications.
In order to meet diversified customer demands, TD350 series VFD provides abundant extension
cards including programmable extension card, PG card, communication card and I/O extension card
to achieve various functions as needed.
The programmable extension card adopts the mainstream development environment for customers
to carry out secondary development easily, fulfilling varied customized needs and reducing customer
cost.
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. 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.
TD350 series VFD supports multiple kinds of popular communication modes to provide complicated
system solutions. It can be connected to the internet with optional wireless communication card, by
which users can monitor the VFD state anywhere and anytime via mobile APP.
TD350 series VFD uses high power density design. Some power ranges carry built-in DC reactor and
brake 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 setting, fault diagnosis and trouble
shooting, and precautions related to daily maintenance. Read through this manual carefully before
installation to ensure that the TD350 series 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
