NVF2-1.5/TS4 is a three-phase AC frequency converter with a rated output power of 1.5 kW and a rated voltage of 380 V. It has a rated frequency of 50/60 Hz.
This manual covers the NVF2 series variable frequency drives produced by CHINT. It includes safety warnings, handling instructions, and detailed installation requirements to ensure reliable operation in industrial environments.
The document also describes wiring diagrams, programmable input/output configurations, functional parameter tables, fault diagnosis, and regular maintenance procedures such as component replacement and EMC compliance measures. This manual is written in Chinese.
| Input voltage range | 380V/220V (±15%) |
|---|---|
| Output frequency range | 0–400 Hz |
| Programmable digital inputs | 6 channels |
| Analog input range | 0 V–10 V |
| Relay outputs | 2 channels |
Do not open the cover while the drive is powered, wait at least 10 minutes after power‑off, and verify that the DC bus voltage is below 25 V before any wiring or inspection.
Install the drive on a non‑combustible surface, keep it away from flammable materials, and disconnect the input power immediately if a fault occurs.
Use a dedicated grounding electrode, a shared grounding electrode, or a ground wire in series, depending on the control system, to ensure safe and effective EMC mitigation.
