- اقتراحات الاختيار
- مطابقة نوع التحميل: Select type G for standard loads (المشجعين, مضخات), and type P for heavy loads (الضواغط, بثق).
- Motor Power Adaptation: The rated power of the frequency converter should be ≥ the rated power of the motor; it is recommended to select one level higher for heavy-duty applications.
- Environmental Condition Consideration: Derating use or additional protective measures are required for high-temperature, high-altitude and dusty occasions.
- Special Function Requirements: Select models with corresponding interfaces for communication networking; select vector control mode for fast response.
- اختيار الملحقات: Optional input and output reactors, filters, braking units, operation panels (universal for CHV100 series).
- استكشاف الأخطاء وإصلاحها
| Fault Code | Fault Cause | Troubleshooting Method |
| OV | DC bus overvoltage | Check grid voltage, extend deceleration time, install braking unit. |
| UV | DC bus undervoltage | Check grid voltage, shorten acceleration time, check input phase loss. |
| OC | Output overcurrent | Check insulation of motor and cables, تقليل الحمل, extend acceleration time. |
| OH | Frequency converter overtemperature | Check cooling fan, clean air duct, reduce ambient temperature. |
| PH | Input phase loss | Check input power supply, tighten wiring terminals, replace damaged fuses. |
| GF | Ground fault | Check insulation of motor and cables, eliminate ground fault points. |
سابعا. Installation and Wiring Key Points
- قبل التثبيت, confirm that the power supply voltage matches the rated voltage of the frequency converter, disconnect the power supply and verify no voltage.
- Adopt 35mm DIN rail mounting or wall-mounted mounting to ensure sufficient heat dissipation space.
- توصيلات الدائرة الرئيسية: R/L1, S/L2, T/L3 are inputs; ش, V, W are outputs; PE is the grounding terminal.
- أسلاك دائرة التحكم: Shielded wires should be used for analog input, with the shielding layer grounded at one end; digital input should avoid routing in the same slot as high-voltage electricity.
- Check parameter settings before power-on, especially basic parameters such as motor rated power, rated current and rated frequency.
