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.

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 and necessary export formalities are needed when exported. Our company

reserves the right to update the information of our products.

1Safety precautions

1.1 What this chapter contains

Read this manual carefully and follow all safety precautions before moving, installing,

operating and servicing the VFD. If these safety precautions are ignored, physical injury or

death may occur, or damage may occur to the equipment.

If any physical injury or death or damage to the equipment occur due to neglect of the safety

precautions in the manual, our company will not be responsible for any damages and we are

not legally bound in any manner.

1.2 Safety definition

Danger: Severe personal injury or even death can result if related requirements are not

followed.

Warning: Personal injury or equipment damage can result if related requirements are not

followed.

Note: Actions taken to ensure proper running.

Trained and qualified professionals: People working on the VFD must have received

professional electrical and safety training and obtained the certificates, and must be familiar

with all steps and requirements of VFD installing, commissioning, running and maintaining

and capable to prevent any emergencies.

1.3 Warning symbols

Warnings caution you about conditions which can result in serious injury or death and/or

damage to the equipment, and advice on how to avoid the danger. Following warning symbols

are used in this manual.
