III. Caractéristiques fonctionnelles

Excellent Control Performance: Adopts DSP control system to realize sensorless vector control, effectively suppressing low-frequency oscillation.
Fonctions de protection complètes: Equipped with multiple protection functions such as overcurrent, surtension, sous-tension, surchauffe, perte de phase, surcharge, ground fault and short circuit.
Rich Application Functions: Built-in PLC simple programming, multi-speed control (jusqu'à 16 speeds), Contrôle PID, frequency swing control, synchronous control, etc..
Strong Communication Capability: Interface RS485 standard, prenant en charge le protocole Modbus RTU, expandable with PROFIBUS-DP, DeviceNet and other fieldbuses.
Flexible Input and Output: 15 digital I/O channels (9DI/6DO by default), 2 analog input channels (0-10V/4-20mA), 2 analog output channels.
Significant Energy-saving Effect: Functions such as Automatic Voltage Regulation (AVR), automatic current limiting, sleep and wake-up, especially suitable for energy-saving transformation of fan and pump loads.
Champ d'application
Fans and Pumps: Boiler induced draft fans, ventilateurs de climatisation centrale, ventilateurs de tour de refroidissement, oilfield water injection pumps, oil transfer pumps, chemical process pumps, etc..
Machines industrielles: Compresseurs d'air, machines de moulage par injection, extrudeuses, machines à imprimer, machines d'emballage, machines textiles, CNC machine tool spindle control.

Suggestions de sélection
Correspondance du type de charge: Select type G for standard loads (les fans, pompes), and type P for heavy loads (compresseurs, extrudeuses).
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.
Sélection d'accessoires: Optional input and output reactors, filtres, braking units, operation panels (universal for CHV100 series).
Dépannage

Code d'erreur	Fault Cause	Troubleshooting Method
VO	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, réduire la charge, 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.
Petite amie	Ground fault	Check insulation of motor and cables, eliminate ground fault points.

VII. Installation and Wiring Key Points

Avant l'installation, 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.
Main circuit wiring: R/L1, S/L2, T/L3 are inputs; U, V, W are outputs; PE is the grounding terminal.
Control circuit wiring: 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.
