This manual covers the installation, operation, maintenance, and troubleshooting of the CHINT NVF5 series variable frequency drive.
The CHINT NVF5 series variable frequency drive utilizes sensorless vector control technology to provide precise control for various industrial applications, including textile, machine tools, and automation equipment. It features functions such as voltage stabilization, torque limiting, and simple PLC capabilities, with support for RS485 communication and expandable Ethernet or Profibus-DP interfaces. This manual is written in Chinese.
| Control Technology | Sensorless Vector Control |
|---|---|
| Operating Temperature Range | -10°C to +45°C |
| Relative Humidity | 5% to 95% RH |
| Altitude Limit | 1000 meters |
It supports standard RS485 and can be expanded with Ethernet, Profibus-DP, Devicenet, and CANopen.
The insulation resistance should not be less than 5MΩ when tested with a 500V megohmmeter.
The drive must be powered off and wait 10 minutes before operating or maintaining it.
