Schneider Electric ATV310HD11N4E Altivar 310 11 kW Drive

What the ATV310HD11N4E drive is and how its reference reads

The ATV310HD11N4E is an Altivar 310 variable speed drive for three-phase asynchronous motors. The datasheet description names an ATV310 of 11 kW and 15 hp on a 380–460 V three-phase supply, so the rating, the supply class and the phase count are all visible in the product description before you open a single table. This particular reference is the unfiltered variant, with no EMC filter.

The datasheet states the supply as 380–460 V with a tolerance of −15 % to +10 %, at 50/60 Hz ± 5 %. Output frequency runs from 0.5 to 400 Hz and the product destination is asynchronous motors. The datasheet lists no EMC filter on this reference, so installations that need conducted-emission control must plan the filtering separately or choose the filtered sibling where one exists in the size.

Heavy duty and normal duty ratings of the ATV310HD11N4E

The ATV310HD11N4E publishes two ratings, which is the first thing to settle when you compare it with a nameplate. On heavy duty it is an 11 kW drive with 24 A continuous output; on normal duty it is a 15 kW drive with 30 A continuous. Heavy duty allows a transient of 36 A for 60 s, while the normal-duty transient is 33 A for the same period.

Line current follows the duty as well: 36.1 A at 380 V and 30.4 A at 460 V on heavy duty. Size upstream protection, cabling and the supply transformer from these line-current figures rather than from the motor current.

Control terminals and Modbus communication on the ATV310HD11N4E

Control wiring is the same logic across the Altivar 310 family, so panel builders can reuse their terminal layout when a motor changes size. This unit offers 4 programmable logic inputs, 1 analogue input, 1 analogue output and 2 outputs, one of them a protected C/O relay.

The Modbus port on the front face supports function codes 03, 06, 16, 23 and 43, so a PLC or SCADA gateway can read and write drive registers and identify the device. Each logic input is sampled every 20 ms, and the analogue input every 10 ms, which is worth remembering when a fast reference change is expected.

Mounting, cooling and ambient limits for the ATV310HD11N4E

It measures 232 × 150 × 171 mm and weighs 3.7 kg. It sits in the 150 mm wide frame and uses an integrated fan; the clamps are sized for larger conductors than the small frames. It must be mounted vertically within ± 10 degrees. Power terminals accept 10 mm², 10 AWG and the datasheet gives a tightening torque of 2.2–2.4 N.m.

For operation the datasheet allows -10 to 55 °C without derating. From 55 to 60 °C the protective cover on the top of the drive must be removed and current derated by 2.2 % per °C. Storage is allowed from −25 to 70 °C, humidity 5–95 % without condensation, and altitude up to 1000 m without derating. Protection is IP20 without the blanking plate on the upper part, with IP4X on top. The environmental classes quoted are 3S2 for dust and 3C3 for chemical pollution.

What to send with an RFQ for the ATV310HD11N4E

• Part number and required quantity
• Motor nameplate: kW, rated current, voltage and frequency, and whether the load is constant or variable torque
• Duty basis: heavy duty or normal duty, and the supply voltage actually available on site
• Whether an EMC filter is required, given that this reference is the unfiltered variant, with no EMC filter
• Panel conditions: cabinet size, ambient temperature, altitude
• Delivery location in Oman or the GCC and required date

Protection and motor control functions of the ATV310HD11N4E

Protection here covers line over- and undervoltage, input phase loss, overcurrent between output phases and earth, short circuit between motor phases and overheating. Motor thermal protection is calculated inside the drive from an I²t model, so a separate thermal relay is optional rather than required by the drive design.

Motor control profiles are V/f, V/f with energy saving (quadratic), and sensorless vector control, with adjustable slip compensation. Ramps are linear from 0 to 999.9 s, with S and U shapes available. Standstill braking is by DC injection for up to 30 s. Braking torque reaches 150 % of nominal motor torque when a braking resistor is fitted, and up to 70 % without one.

Speed range is 1 to 20 for an asynchronous motor, and transient overtorque is 170 to 200 % of nominal motor torque depending on drive rating and motor type.

Choosing the ATV310HD11N4E against neighbouring Altivar 310 ratings

The nearest references in the same Altivar 310 supply class are listed below, sorted by heavy-duty power. When a motor sits right on a boundary, compare continuous output current, not kilowatts, because this drive is judged on 24 A at heavy duty and 30 A at normal duty.

Remember that the supply-voltage range, 380–460 V, is common to every reference here; if your network is 230 V single-phase or 690 V, this series is not the right branch of the catalogue.

Where the ATV310HD11N4E fits in Oman and the GCC

Upper ratings serve larger fans, pumps and conveyors where soft starting and speed matching save mechanical wear. In Oman and the wider GCC such machines run in desalination plant auxiliaries, utility buildings, water treatment, light industry and oil and gas support systems. Heat and dust are the practical challenges: the drive is rated to 55 °C without derating and carries dust class 3S2, but the cabinet design still decides how long it lives.
