III. Caracteristici funcționale

Excellent Control Performance: Adopts DSP control system to realize sensorless vector control, effectively suppressing low-frequency oscillation.
Funcții de protecție cuprinzătoare: Equipped with multiple protection functions such as overcurrent, supratensiune, subtensiune, supratemperatura, pierdere de fază, suprasarcina, ground fault and short circuit.
Rich Application Functions: Built-in PLC simple programming, multi-speed control (până la 16 viteze), PID control, frequency swing control, control sincron, etc.
Strong Communication Capability: Interfață RS485 standard, care acceptă protocolul 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 canale de ieșire analogică.
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.
Domeniul de aplicare
Fans and Pumps: Boiler induced draft fans, central air conditioning fans, cooling tower fans, oilfield water injection pumps, oil transfer pumps, chemical process pumps, etc.
Utilaje industriale: Compresoare de aer, mașini de turnat prin injecție, extrudere, mașini de imprimat, mașini de ambalare, utilaje textile, CNC machine tool spindle control.

Sugestii de selecție
Potrivirea tipului de încărcare: Select type G for standard loads (fani, pompe), and type P for heavy loads (compresoare, extrudere).
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.
Selectarea accesoriilor: Optional input and output reactors, filtre, braking units, operation panels (universal for CHV100 series).
Depanare

Cod de eroare	Fault Cause	Metoda de depanare
OV	Supratensiune magistrală DC	Check grid voltage, extend deceleration time, install braking unit.
UV	Subtensiune magistrală DC	Check grid voltage, shorten acceleration time, check input phase loss.
OC	Output overcurrent	Check insulation of motor and cables, reduce load, 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	Defecțiune la pământ	Check insulation of motor and cables, eliminate ground fault points.

VII. Puncte cheie pentru instalare și cablare

Înainte de instalare, 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.
Cablajul circuitului principal: R/L1, S/L2, T/L3 are inputs; U, V, W are outputs; PE is the grounding terminal.
Cablajul circuitului de control: 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.
