Schneider Electric ATV320U11N4W Altivar Machine Drive 1.1 kW

ATV320U11N4W: enclosed Altivar Machine drive, 1.1 kW, IP66

The Schneider Electric ATV320U11N4W is an Altivar Machine ATV320 variable speed drive in the enclosed, high-protection version. It is rated 1.1 kW (heavy duty) on a 380 to 500 V three-phase supply with 3.0 A continuous output, and its IP66 housing lets it be mounted on the machine or on a wall without a separate control cabinet.

Reading the code: ATV320 is the Altivar Machine family, U11 is the 1.1 kW rating, N4 the 380 to 500 V three-phase supply and W the enclosed, high-IP construction described in the product title. Seven Star LLC supplies the ATV320U11N4W in Oman and the GCC as an independent supplier in Muscat.

ATV320U11N4W technical specifications

How the ATV320U11N4W works

The drive rectifies the three-phase supply and inverts it to a variable-frequency output for an asynchronous or synchronous motor. In the ATV320 range, vector control and motor-optimising features serve machines such as conveyors, mixers, packaging lines and pump or fan systems that need good torque at low speed.

The W version places the power section and control inside a sealed enclosure, so heat is shed through the housing rather than through open vents. Because the enclosure is IP66, dust and washdown water do not reach the electronics, which is the main reason to prefer it over the IP20 compact and book styles.

Where the ATV320U11N4W fits and related parts

Within the ATV320 family, the same 1.1 kW rating is available in other mounting styles, for example compact and book versions, which are intended for installation inside a panel. Choose the ATV320U11N4W when no cabinet space is available or when the drive will sit on the machine frame. Comparable Schneider drives for larger pumps and fans include the Easy Altivar ATV610 range, such as the ATV610D11N4, which suits 11 kW cabinet installations.

Typical accessories include communication options, remote display terminals and brake resistors; the options available for the enclosed version should be confirmed against the catalogue before ordering.

Selection and ordering checklist

• Motor power and current: 1.1 kW with 3.0 A output; check the motor nameplate current.
• Supply 380 to 500 V three phase.
• Environment: confirm that the IP66 enclosure suits dust, water spray or washdown.
• Fieldbus: Modbus and CANopen on board; confirm if another bus is needed.
• Cable lengths against the Class C2 filter limits.
• Mounting surface for a 6 kg drive of 250 x 340 x 200 mm.

Installation, commissioning and maintenance

Fix the drive to a flat, rigid surface and keep the cable glands sealed to preserve the IP66 rating. Open the cover only in clean, dry conditions and refit gaskets correctly. Wire line and motor cables using the proper shielding and earthing so the integrated filter is effective.

Commissioning follows the usual sequence: enter motor data, run auto-tune, set ramps, define the run source and check direction of rotation. Maintenance includes visual checks of seals, inspecting for condensation inside the cover after wet cleaning, and keeping the heat-dissipating surfaces free of deposits.

Typical applications in Oman and the GCC

The enclosed ATV320 is useful for small pumps, conveyors in food and beverage plants, packaging machinery, ventilation and dosing skids in water treatment and desalination, and port or logistics equipment where dust and humidity are high. In hot, sandy locations the sealed housing prevents ingress, but direct sun exposure can raise temperatures, so shade the drive and check the temperature limits in the manufacturer manual.

Practical points for machine builders using the ATV320U11N4W

A drive mounted directly on the machine removes the long motor cable and the cabinet, which cuts wiring time and reduces electromagnetic emissions. At the same time, it places the electronics near vibration, spray and impacts, so use proper strain relief on every gland and keep unused entries plugged with certified blanking elements.

Plan the control wiring early: Modbus and CANopen both arrive on the RJ45 connector at the front, so cable routing to the PLC should avoid the motor cable. For speed reference, use a shielded cable and ground the screen at the drive. A removable commissioning file or saved parameter set makes replacement fast; after a swap, load the saved configuration and verify the motor data before releasing the machine.

• Keep a spare unit for production-critical lines.
• Use a sealed pushbutton or remote display where operators need local control.
• Document the parameter set and firmware version in the machine file.
