ATV320U40N4B Variable Frequency Drive Altivar 320 4.0kW 3-ф/380

ATV320U40N4B: Schneider Electric Altivar 320 variable frequency drive rated at 4 kW (3-phase 380 V input, 3-phase 380 V output). We use it for a small conveyor, gate, fan, or machine drive when the project needs Altivar diagnostics and a predictable automation path.

• Parameters: 9.5 A output current, IP20, 150% overload, maximum frequency 600 Hz.
• What matters: ATV320 brings machine-drive logic, STO, and a compact body; CANopen and other fieldbus options are available.
• Check before use: Before commissioning, check motor current, load type, cable length, and the control method.

Schneider Electric Altivar 320: where this series fits

Altivar 320 is a machine-drive series for OEM equipment, packaging, feeders, and drives with safety/fieldbus requirements. Our catalog currently has 22 active items in this series: 0.4-7.5 kW, supply variants 1-phase 220 V, 3-phase 380 V, IP20 enclosures, EMC filter: yes. Schneider Electric is not the cheapest route. The usual reason is simpler: Altivar diagnostics, SoMove, documentation, and a predictable cabinet startup.

Typical jobs for Altivar 320

• Common mechanisms: packaging machines, conveyors, dosing units, winders, and compact process modules.
• Selection: first check motor current, load duty, supply voltage, IP rating, and motor cable length.
• Commissioning: with Altivar, define the command source, speed reference, network protocol, and braking need before wiring.

When Altivar 320 is not the right drive

We do not recommend Altivar 320 for power above 7.5 kW in our catalog or demanding dynamics where ATV340 is a better fit. In those jobs, another Schneider Electric series may be more logical, or INVT / Veichi may be enough when the project does not specifically require Altivar.

Our field note

Schneider Electric is usually chosen for sites with BMS, SCADA, or an older Altivar already in the cabinet. Predictability matters there. Before ordering we ask for a motor nameplate photo and a short mechanism description. That filters out 220/380 V, IP, and braking mistakes early.
