Preface
The Ecowatt Drive K320 series is a high performance variable-frequency drive (VFD) that
specific designed to be applied in Fan application which integrates the latest Safety and
Energy-saving functions for the demand control ventilation system. It can drive both
synchronous motors and asynchronous motors.
[Energy saving]
This VFD adopts dedicated PID control mode for Demand Control Ventilation system to
optimizes the voltage output of the VFD to the actual load of the FAN motor, thus minimizing
its power consumption.
[Easy control]
It supports multiple kinds of popular control signal (0-10V signal, 4-20mA) and Modbus
communication to realize complicated system solutions.
[High performance]
It armed with advanced vector control technology and the latest digital processor dedicated
for motor control, thus enhancing product reliability and adaptability to the environment.
[Reliable]
Ecowatt Drive K320 uses high power density design. Some power ranges carry built-in DC
reactor and Braking 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, and precautions related to daily maintenance.
Read this manual carefully before installation to ensure the VFD is installed and operated in a
proper manner to give full play to its excellent performance and powerful functions.
