This manual introduces the installation, wiring, parameter setting, fault diagnosis and countermeasures and daily maintenance related precautions of EDS900 series variable frequency drive.
The EDS900 series is a mini‑type frequency transformer designed for general industrial three‑phase AC induction motor control. It offers advanced control methods, PID regulation, simple PLC functions, programmable I/O, remote synchronization and various other features to improve system reliability and reduce cost.
This manual covers safety precautions, installation environment, wiring diagrams, parameter configuration, operation modes, fault diagnosis, maintenance procedures and optional accessories such as external brake resistors. Users are advised to read it thoroughly before commissioning the device. This manual is written in Chinese.
| Power rating | 0.4‑1.5 kW |
|---|---|
| Supported motor type | Three‑phase AC induction motor |
| Minimum insulation resistance | ≥ 5 MΩ |
| Altitude derating | Reduce output current by 10 % per 1500 m above 1000 m |
Do not connect AC power to the V, W output terminals, avoid installing on flammable material, ensure proper grounding, keep the work area dry, and only qualified personnel should perform wiring.
For every 1500 m increase in altitude above 1000 m, reduce the output current by about 10 % of the rated current.
