Schneider Electric ATV310H037N4E 0.37 kW Altivar 310 Drive

ATV310H037N4E: 0.37 kW Altivar 310 drive for simple machines

The ATV310H037N4E is a Schneider Electric Altivar 310 variable speed drive, listed in its datasheet as: Variable speed drive ATV310 – 0.37 kW – 0.5 hp – 380…460 V – 3 phase. The datasheet gives its specific application as simple machines, and the rating as 0.37 kW (0.5 hp) for heavy duty on a three-phase 380 to 460 V supply. Seven Star LLC supplies the ATV310H037N4E in Oman and the GCC as an independent supplier in Muscat.

Two details in the datasheet set it apart from the HVAC-oriented Altivar 212 drives: it has no EMC filter, and it is self-cooled, with no fan, because its losses are only 22.7 W at rated current. That makes it a quiet, compact drive for small conveyors, mixers, small pumps and fans on machines.

ATV310H037N4E datasheet values at a glance

Ratings, overload and control of the ATV310H037N4E

The ATV310H037N4E lists a line current of 2.1 A at 380 V and 1.8 A at 460 V, both for heavy duty, and an apparent power of 1.4 kVA at 460 V. The continuous output current is 1.5 A with a transient of 2.3 A for 60 s. Since the rating is expressed for heavy duty, the motor nameplate current should be at or below 1.5 A.

Output frequency spans 0.5 to 400 Hz, with a speed range of 1 to 20 for asynchronous motors and a switching frequency adjustable from 2 to 12 kHz around a nominal 4 kHz. Control profiles are voltage/frequency ratio, an energy-saving quadratic U/f for fans and pumps, and sensorless vector control. The transient overtorque is 170 to 200 % of nominal motor torque depending on the drive rating and motor type, and braking torque reaches up to 70 % of nominal without a braking resistor; DC injection braking to standstill takes less than 30 s.

Ramps are linear from 0 to 999.9 s with S and U shapes available. Motor thermal protection is calculated by the drive from I²t, and the other protections listed are line overvoltage and undervoltage, overcurrent to earth, overheating, motor-phase short circuit and input phase loss on three-phase supplies.

Terminals and communication of the ATV310H037N4E

The control board has one analogue input AI1 that can be set to 0 to 20 mA, 0 to 10 V or 0 to 5 V, four programmable discrete inputs LI1 to LI4 on 24 V (18 to 30 V), one software-configurable analogue output AO1 (0 to 10 V or 0 to 20 mA) and two discrete outputs: a logic output LO+/LO- and a protected relay output R1A, R1B, R1C with one changeover contact. The relay switches 3 A at 250 V AC on a resistive load and 2 A on an inductive load.

The Modbus port is an RJ45 on the front face with 2-wire RS 485, RTU frame, addresses 1 to 247 and speeds of 4800, 9600, 19200 or 38400 bit/s. Supported services include reading and writing holding registers and device identification. For a small machine this means the ATV310H037N4E can be commanded from a PLC without an option card.

The ATV310H037N4E compared with the ATV212 drives

Altivar 212 references such as the ATV212HU30N4 (3 kW) or ATV212HU40N4 (4 kW) are specified for HVAC pumps and fans, carry an integrated Class C2 EMC filter and offer building-automation protocols. The ATV310H037N4E is a different class of drive: far smaller at 0.37 kW, aimed at simple machines, without an EMC filter and with Modbus only.

So if the load is an HVAC fan or pump of several kilowatts, the ATV212 family in the datasheets is the closer fit. If it is a sub-kilowatt machine drive, the Altivar 310 is the match.

Installing the ATV310H037N4E in a machine panel

The ATV310H037N4E measures 72 mm wide, 143 mm high and 130 mm deep and weighs 0.8 kg. Power and motor terminals (L1, L2, L3, U, V, W) clamp 1.5 to 2.5 mm² (16 to 14 AWG) at 0.8 to 1 N.m, so it is a drive for light cables only.

The operating position is vertical within 10 degrees. Ambient temperature is -10 to 55 °C without derating; from 55 to 60 °C the datasheet allows operation with the top protective cover removed and a current derating of 2.2 % per °C. Storage is -25 to 70 °C, humidity 5 to 95 % without condensation, altitude up to 1000 m without derating, and the enclosure is IP20 with an IP4X top. Dust class 3S2 and chemical class 3C3 are listed.

With no EMC filter inside, an external filter or screened-cable practice is the installer’s responsibility where emission limits apply. The datasheet lists IEC 61800-3 and IEC 61800-5-1, EMC immunity levels up to level 4 for fast transients, and CE, EAC and KC certification.

Selection checklist for the ATV310H037N4E

• Motor nameplate current at or below 1.5 A, three-phase, 380 to 460 V.
• Duty: heavy duty rating; confirm that the load torque curve suits a 170 to 200 % transient overtorque.
• EMC: no filter is built in, so decide on an external filter where required.
• Control: one analogue input, four logic inputs, Modbus RJ45.
• Cable: terminals accept 1.5 to 2.5 mm².
• Status: the datasheet we used shows no discontinuation notice; confirm with us at quotation.

Where the ATV310H037N4E is applied in Oman and the GCC

In Oman and the GCC a drive of this size turns up on small conveyors in packaging and warehouse lines, mixers, dosing pumps, small fans and workshop machinery. The 0.37 kW rating and heavy-duty basis suit constant-torque loads that need soft starting and speed adjustment rather than the quadratic loads of large HVAC plant.

Because it is self-cooled with only 22.7 W of loss, it relies on panel air rather than a fan. In hot or dusty environments the panel should be ventilated and filtered, and the 55 °C limit without derating should be compared with the measured temperature at the drive.
