Schneider Electric ATV310HD15N4E Altivar 310 15 kW Drive

What the ATV310HD15N4E drive is and how its reference reads

ATV310HD15N4E is one step in the Altivar 310 line, which Schneider Electric positions for simple machines. It drives asynchronous motors from a three-phase 380–460 V supply and is rated 15 kW (20 hp) on the heavy-duty basis used throughout the datasheet. The build is the unfiltered variant, with no EMC filter, and the heat sink is part of the assembly.

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.

ATV310HD15N4E technical specifications

Heavy duty and normal duty ratings of the ATV310HD15N4E

The ATV310HD15N4E publishes two ratings, which is the first thing to settle when you compare it with a nameplate. On heavy duty it is a 15 kW drive with 33 A continuous output; on normal duty it is a 18.5 kW drive with 36 A continuous. Heavy duty allows a transient of 49.5 A for 60 s, while the normal-duty transient is 39.6 A for the same period.

Line current follows the duty as well: 46.5 A at 380 V and 38.5 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.

Choosing the ATV310HD15N4E 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 33 A at heavy duty and 36 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.

Control terminals and Modbus communication on the ATV310HD15N4E

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.

What to send with an RFQ for the ATV310HD15N4E

• 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 ATV310HD15N4E

The drive watches both sides of the power stage. On the line side it reacts to overvoltage, undervoltage and loss of an input phase; on the motor side it reacts to overcurrent to earth and to short circuits between phases. Overheating is monitored on the drive itself, and motor heating is estimated continuously by an I²t calculation.

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.

Where the ATV310HD15N4E 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.

Mounting, cooling and ambient limits for the ATV310HD15N4E

It measures 330 × 180 × 191 mm and weighs 6.3 kg. It belongs to the large-frame end of the series, where the housing is 180 mm wide and the integrated fan does the heavy lifting. It must be mounted vertically within ± 10 degrees. Power terminals accept 16–25 mm², 4 AWG–3 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.
