Schneider Electric ATV340D11N4 11 kW Machine Drive

ATV340D11N4: 11 kW Altivar Machine ATV340 heavy-duty drive

The ATV340D11N4 is a Schneider Electric variable speed drive listed in the datasheet as: variable speed drive, Altivar Machine ATV340, 11kW, heavy duty, 400V, 3 phases. The ATV340 is the Altivar Machine drive for demanding machines that need a communication-rich, safety-capable controller. At 11 kW heavy duty it addresses medium-power hoists, presses, packaging and processing lines that run on a standard industrial supply. Seven Star LLC supplies the ATV340D11N4 in Oman and the GCC as an independent supplier based in Muscat.

Reading the reference: ATV340 is the range, D11 the 11 kW rating and N4 the three-phase 400/480 V supply class. The title in the datasheet states heavy duty, so the 11 kW figure is already on the heavy-duty basis.

Technical specifications of the ATV340D11N4

Control, communication and safety functions of the ATV340D11N4

Communication protocols listed: Modbus serial. EMC filter: Class C3 EMC filter integrated. Discrete inputs: 5. Analogue inputs: 2. Relay outputs: 2. Braking: By DC injection. Use the lists above to confirm which communication ports and safety functions are fitted on board and which need an option module for your machine standard.

Safety and motor-technology considerations for the ATV340D11N4

An 11 kW machine drive is often the point where the safety concept matters: an emergency stop must remove torque reliably, and many lines add a controlled stop before power removal. Check the safety functions listed in the datasheet and the safety integrity data, then compare them with the machine risk assessment instead of assuming equivalence.

Because the drive also supports synchronous motors, it can replace a variable-speed gearmotor with a more efficient permanent-magnet one. In that case the motor parameters and the encoder or sensorless profile need extra commissioning care.

Installation, wiring and commissioning of the ATV340D11N4

Mount on a flat panel with clearances for convection and fans, observe the EMC wiring practice and keep the motor cable as short as the layout allows. Terminate the safety input wiring separately from the signal wiring, and test the stop function by actually removing the safety input.

At commissioning enter the motor data, run the tuning, select the control profile and set the network address. Keep a copy of the settings; the drive can be loaded from a backup when it is replaced.

Typical applications of the ATV340D11N4 in Oman and the GCC

Typical applications in the region are overhead cranes and hoists in workshops, conveyor lines in logistics and packaging, and pumps and compressors on machine-builder skids. Ambient temperature and dust load decide the cabinet cooling design.
