Setup Guide

To set up the GK3000, begin by ensuring all electrical connections are secure and meet the specified voltage and current requirements. Follow the manufacturer's instructions for mounting the inverter in a well-ventilated area to prevent overheating.

Configure the inverter using the provided software or the built-in display panel. Select the appropriate control mode (vector or V/F) based on your application needs. Connect the inverter to your motor and other devices according to the wiring diagram provided in the manual.

Perform a soft start to test the system and ensure all parameters are correctly set. Finally, integrate the inverter with your control system using the supported communication protocols.

Troubleshooting

Fault Alarm and Troubleshooting
When the inverter is abnormal, protection function acts: LED displays fault code and the content, fault relay acts, the inverter stops output,, and the motor coast-downs to stop. GK3000 series inverter’s fault contents andtroubleshootinareee shown in Table 7-1. After fault alarm occurs, fault phenomenon should be recorded in detail, the fault should be processed according to Table 7-1. When in need of technical assistance, please contact your supplier.

Preservation and Maintenance

Potential hazards exist due to aging, wear and tear of inverter internal components as well as environmental influences to the inverter, such as temperature, humidity,, particles, etc. Therefore, daily inspection, periodic preservation, and maintenance must be performed on the inverter and its driving mechanism during their storage and operation.

Daily Maintenance
The following must be verified before starting up：

No abnormal vibration and no abnormal noise;
No abnormal heat.
No abnormal ambient temperature;
The ammeter satisfies the specification.
Fan is working in good condition.

Periodic Preservation and Maintenance

Periodic Maintenance
Cut off the power when inverter is maintained thermally, check after the main circuit power indicator light is off. The checking content is shown in Table 8-1.

Thermally maintaining
To let the inverter work well for a long time, the user must maintain the inverter thermally. The replacement time of the elemint of the inverter is shown in Table 8-2.

Items	Time criterion
Cooling fans	2-3 years
Electrolytic capacitors	4-5 years
Printed circuit board	5-8 years
Fuse	10 years

The working condition of the inverter is as follows:

Environment temperature: average 30 °C;
Load coefficient: under 80%;
Running time: under 12 hours every day

Communication overview

Our series of inverters provide users with a common industrial control RS485 communication interface, in which the MODBUS standard protocol is used for communication. The inverters can be used as slave connected to the host (such as PLC controller, PC), both of which have the same communication interface and protocol, for the purpose of centralized monitoring of the inverters. Or one inverter can be used as a host and the other inverters as slaves, all connected with an RS-4855 communication interface, to achieve multi-machine interaction of the inverters. And with this communication interface, a Keyboard can also be connected to inverters for remote operation.
The MODBUS communication protocol of the inverter supports two transmission modes: RTU mode and ASCII, and either can be chosen. The following is a detailed description of the communication protocol of the inverter.
