1. Introducció
This manual provides essential information for the safe and efficient operation of your ATO 5 hp 3.7 kW 460V Three-Phase Variable Frequency Drive (VFD). Please read this manual thoroughly before installation, operation, or maintenance to ensure proper usage and prevent potential hazards.
2. Informació de seguretat
ADVERTÈNCIA: risc de descàrrega elèctrica.
- Read the manual and follow all safety instructions before operation.
- Do not remove the cover while power is applied.
- Wait for at least 10 minutes after disconnecting power supply to open the cover. This allows residual voltage per dissipar-se.
- Do not connect power to output terminals.
- The inverter must be securely grounded (earth).
- Només personal qualificat ha de fer la instal·lació i el manteniment.

5. Configuració i instal·lació
Proper installation is crucial for the VFD's performance and safety. Consult a qualified electrician for wiring if you are unfamiliar with industrial electrical systems.
5.1 Connexions de cablejat
Connect the three-phase input power to the designated input terminals (R, S, T) and the motor to the output terminals (U, V, W). Ensure proper grounding of the VFD chassis.
- Potència d'entrada: Connect 3-phase 460V AC to the input terminals.
- Connexió del motor: Connect your 3-phase induction motor to the output terminals.
- Posada a terra: Ensure the VFD is properly grounded to prevent electrical hazards.
5.2 Motor Compatibility
When selecting a VFD, ensure:
- The rated current of the VFD is greater than the rated current of your motor.
- The rated power of the VFD is greater than the rated power of your motor, preferably by at least one level.
If unsure, provide your motor nameplate photo, input power supply details, and requirements to customer support for assistance.
6. Instruccions de funcionament
The VFD supports various control methods and programmable parameters.
6.1 Funcionament bàsic
The digital operator panel allows for direct control and parameter adjustment.
- MENÚ/ESC: Access menu or exit current setting.
- ENTER/DATA: Confirm selection or enter data.
- FWD/REV: Control forward/reverse direction.
- Fletxes AMUNT/AVALL: Adjust frequency or navigate parameters.
- JOG/REV: Jog operation or reverse direction.
- ATURAR/REINICIAR: Stop operation or reset errors.
6.2 Frequency Control Methods
The VFD offers several methods to control motor frequency:
- Switch Button Control: Use external switch signals to start/stop the VFD and activate multi-speed settings.
- Control analògic: Control frequency using a 5V or 0-20mA analog signal, in conjunction with switch control for start/stop.
- Control del potenciòmetre: Direct frequency control using the VFD's built-in potentiometer input terminal.
- Modbus-RTU Control: Utilize the RS485 interface for data transmission with Modbus-RTU protocol to monitor, modify frequency, start, and stop the VFD.
- DTU Wireless Remote Control: Combine a DTU terminal with the VFD for wireless transmission, where the DTU outputs an analog quantity to control VFD frequency.
6.3 Paràmetres de programació
The VFD supports customization of various parameters, including acceleration/deceleration time, frequency settings, and motor protection. Refer to the detailed programming guide (if provided separately) for specific parameter codes and values.
7. Manteniment
Un manteniment regular garanteix la longevitat i el rendiment òptim del vostre variador de freqüència.
- Mantingueu el variador de freqüència net i lliure de pols i deixalles.
- Assegureu-vos que hi hagi una ventilació adequada al voltant de la unitat per evitar el sobreescalfament.
- Comproveu periòdicament totes les connexions del cablejat per comprovar si estan ben ajustades i si hi ha signes de desgast.
- Inspect cooling fans for proper operation and clear any obstructions.
8. Solució De Problemes
8.1 Problemes comuns i solucions
- Volum de sortida incorrectetage (e.g., 380V instead of 460V): If the factory default output voltage is incorrect, adjust parameter P0.08 to the desired voltage (e.g., P0.08 = 460V).
- VFD Not Responding: Check power connections, input voltage, and ensure no error codes are displayed.
- El motor no funciona: Verify motor wiring, VFD output frequency, and motor parameters.
8.2 Restabliment de fàbrica
To restore the VFD to factory settings, set parameter Pd.01 = 1.
