This document is the user manual for CDI9000 series frequency converter, which introduces the installation, operation, keyboard operation, function parameters, input and output functions, and other aspects of the product.
This manual covers the complete lifecycle of the CDI9000 series frequency converters, from safety precautions and acceptance inspection to detailed installation, wiring, and operation procedures. It also explains keyboard functions, parameter configuration, input/output features, and fault diagnosis.
Appendices include technical specifications, optional accessory selection, typical wiring diagrams, and a knowledge Q&A section to help users understand inverter principles and best‑practice troubleshooting. This manual is written in Chinese.
| Rated Voltage (380‑415 V series) | 380‑415 V |
|---|---|
| Rated Power (CDI9000‑G075T4) | 75 kW |
| Rated Output Current (CDI9000‑G075T4) | 150 A |
| Rated Power (200‑230 V series, model G1R5T2) | 1.5 kW |
| Rated Output Current (200‑230 V series, model G1R5T2) | 7 A |
Only qualified personnel may perform installation and maintenance, the inverter must be fully covered before energizing, and the power must be disconnected for at least 5 minutes to discharge internal capacitors.
Install an AC reactor when the power‑to‑inverter capacity ratio exceeds 10:1, when there are thyristor loads or power‑factor correction devices, or when the three‑phase voltage imbalance is greater than 3 %.
The start‑up current is limited to 150 % of the rated current (or 125‑200 % depending on the model) to protect the inverter and motor.
Models up to 7.5 kW have internal regenerative braking; larger models require an external braking resistor to provide additional braking torque.
