Preface
Thank you for choosing Astraada DRV-28 inverters.
DRV-28 is a high-performance and multipurpose inverter aiming to integrate synchronous motor drive
with asynchronous motor drive, and torque control, 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. DRV-28 series inverter adopts
customized and industrialized design to realize excellent control performance through optimized
functions and flexible applications.
In order to meet diversified customer demands, DRV-28 series inverter 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.
DRV-28 series inverter 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 users can monitor the inverter state anywhere any time via mobile
APP.
DRV-28 series inverter 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 setup, fault diagnosis and trouble
shooting, and precautions related to daily maintenance. Read through this manual carefully before
installation to ensure DRV-28 series inverter is installed and operated in a proper manner to give full
play to its excellent performance and powerful functions.
