1. Introducció
This manual provides essential information for the safe and efficient installation, operation, and maintenance of the Schneider Electric Altivar Machine ATV320 Series Variable Speed Drive. This device is designed to control the speed of three-phase asynchronous and synchronous motors in various industrial applications, offering precise control and energy efficiency.
2. Informació de seguretat
PERILL: Risk of electric shock. This equipment contains high voltage. Only qualified personnel should perform installation, maintenance, and troubleshooting. Disconnect all power before working on the drive.
ADVERTIMENT: The motor can start unexpectedly. Ensure proper lockout/tagout procedures are followed. Read and understand all instructions before proceeding.
- Seguiu sempre els codis elèctrics locals i nacionals.
- Assegureu-vos de la connexió a terra correcta del variador i del motor.
- Do not operate the drive with damaged components.
- Protegiu la unitat de la humitat, la pols i els ambients corrosius.
3. Configuració i instal·lació
3.1. Desembalatge i inspecció
Carefully unpack the drive and inspect it for any signs of damage during transit. Report any damage to the carrier immediately. Verify that all components listed in the packing list are present.
3.2. Muntatge
Mount the ATV320 drive vertically on a flat, stable surface, ensuring adequate clearance for ventilation. Maintain a minimum of 50mm (2 inches) clearance above and below the unit for proper airflow. Use appropriate screws and mounting hardware suitable for the drive's weight.
3.3. Cablatge
All wiring must be performed by a qualified electrician in accordance with local and national electrical codes.
- Cablejat d'alimentació: Connect the three-phase AC input (L1, L2, L3) to the designated terminals. Ensure the voltage matches the drive's specifications (380-500 Vac).
- Cablejat del motor: Connect the motor phases (U, V, W) to the drive's output terminals. Ensure correct phase rotation.
- Posada a terra: Connect the protective earth (PE) terminal of the drive to a reliable ground point.
- Cablejat de control: Connect control signals (e.g., start/stop, speed reference, fault reset) to the appropriate digital and analog input terminals. Refer to the wiring diagram provided with the drive for specific terminal assignments.

3.4. Engegada inicial
Before applying power, double-check all wiring connections. Apply power to the drive. The LED display on the control panel should illuminate. Follow the drive's quick start guide or parameter manual for initial configuration and motor auto-tuning.
4. Instruccions de funcionament
4.1. Tauler de control acabatview
The ATV320 features an integrated control panel with a 4-digit, 7-segment LED display and navigation buttons (ESC, OK, Up, Down, Left, Right) for parameter setting and monitoring. A green rotary knob is typically used for local speed reference.
4.2. Funcionament bàsic
- Inici/Parada: The drive can be started and stopped via digital inputs, serial communication, or the local control panel.
- Control de velocitat: Speed reference can be set via analog input (e.g., 0-10V, 4-20mA), serial communication, or the local potentiometer/buttons.
- Seguiment: The display shows various parameters such as motor speed (Hz or RPM), output current, output voltage, i codis d'error.
4.3. Configuració dels paràmetres
Access the parameter menu using the navigation buttons. Key parameters include:
- Vol nominal del motortage, current, frequency, and speed.
- Acceleration and deceleration ramps.
- Minimum and maximum output frequencies.
- Control mode (e.g., V/F, Sensorless Vector Control).
- Digital input and output assignments.
5. Manteniment
Regular maintenance ensures optimal performance and extends the lifespan of the drive. Always disconnect power before performing any maintenance.
- Neteja: Periodically clean the drive's heat sinks and ventilation openings to prevent dust accumulation, which can impede cooling. Use compressed air or a soft brush.
- Connexions: Check all electrical connections for tightness and signs of corrosion. Retighten as necessary.
- Control ambiental: Assegureu-vos que l'entorn operatiu es mantingui dins dels límits de temperatura i humitat especificats.
- Substitució del ventilador: Cooling fans have a finite lifespan. Inspect fans for proper operation and replace them if they become noisy or stop working. Refer to the drive's specific service manual for fan replacement procedures.
