Schneider Electric Altivar Machine ATV 320 and ATV 340 variable speed drives

The Altivar Machine range of variable speed drives from Schneider Electric includes the ATV320 and -340 models, which are designed to handle sophisticated automation architectures and demanding applications without adding to overhead.

The variable speed drives enhance motor control performance by reducing application task cycle time (1 ms) in synchronous, asynchronous, servo and reluctance motors. The ATV320 allows open-loop control of speed and torque, while the ATV340 allows open and closed-loop control of speed, torque and position.

The range also supports a variety of communication protocols such as ModBus TCP, Ethernet IP, CANopen, Sercos III. In addition, the ATV340 model allows real-time communication with automation architectures. Their modular design standards are designed to allow for easy selection, fast commissioning and reduced installation time. The ATV320 in particular is available in both compact and book form factors offering efficient space usage in various cabinet layouts.

The printed circuit boards on the devices are coated in accordance with IEC 61721-3-3, with class 3C3 as standard, to protect against corrosion in harsh environments. Embedded safety functions from STO and SIL3 PLe up to the most demanding functions are compatible with synchronous and servo motors.
