Preface
Thank you for choosing the ST600 series high-performance multifunction VFD.
The frequency inverter ST600 series VFD is a high-performance and multipurpose VFD aiming to
integrate the driving of synchronous motors and asynchronous motors, and torque control, speed
control with position control. It is armed with advanced vector control technology and the latest digital
processor dedicated to motor control, thus enhancing product reliability and adaptability to the
environment. The frequency inverter ST600 high-performance multifunction VFD adopts customized
and industrialized design to realize excellent control performance through optimized functions and
flexible applications.
To meet the basic needs of customers, VFDs of power range from 4 to 110 kW are developed for the
ST600 series. To meet diversified customer demands, the frequency inverter ST600 series high-
performance multifunction VFD provides abundant expansion cards including a programmable
expansion card, PG card, communication card and I/O expansion card to achieve various functions
as needed.
The programmable expansion card adopts 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 ST600 series high-performance multifunction VFD supports multiple kinds of popular
communication modes to realize complicated system solutions. It can be connected to the internet
with an optional wireless communication card, by which users can monitor the VFD state anywhere at
any time via mobile app.
The VFD uses high power density design. Some power ranges and models 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 setup, fault diagnosis and
troubleshooting, as well as precautions related to daily maintenance. Read through this manual
carefully before installation to ensure that the frequency inverter ST600 series high-performance
multifunction VFD is installed and operated in a proper manner to give full play to its excellent
performance and powerful functions.
