Schneider Electrics ATV320U75N4B inverter is a three-phase variable speed asynchronous motor unit. It has a rated power of 7.5 kW and a supply voltage of 400 VAC. The dimensions of the variable frequency drive are: length 150mm, width 232mm and overall depth 232mm.

Altivar Machine ATV320 variable speed drives are simple yet advanced machines. They are designed for original equipment manufacturers and meet the requirements of simple and advanced applications for three-phase synchronous and asynchronous motors, from 0.18 to 15 kW. This type of VFD is the perfect solution to improve the efficiency of machines in a wide range of applications.

Features and benefits

• Advanced automation features through simple open loop motor control for asynchronous and synchronous motors - also applies to low speed dynamic accuracy for start/stop applications
• Advanced connectivity with automation frameworks such as EtherNet/IP - Modbus TCP, Profinet EtherCAT, Profibus, CANopen and DeviceNet
• Features such as ATVLogic that bring versatility and application expertise to machines
• Altivar Machine ATV320 variable speed drives continue the tradition of their predecessors in terms of robustness and reliability
• To optimize machine uptime, especially when production changes, safety diagnostics and operation, system integration and network configuration can be achieved in a timely manner
• The ATV320 is designed for easy and cost-effective installation for a number of machine configurations and for placement indoors in locations such as cabinets and machine frames
• With a rugged, durable and reliable design and also IEC 60721-3-3 Class 3C3 coated printed circuit boards, these VFDs can extend machine availability in harsh conditions
• This series has several mounting options, depending on the machine (vertical, horizontal, with the option to offset the control module when the unit is mounted sideways, in a side-by-side arrangement)
• Comprehensive integrated safety range for machines with additional safety torque off, four complete safety monitoring functions to simplify certification and compliance of the machine with the Machinery Directive 2006/42/EC
• Easy-to-mount communication boards in cassette format.

Where is a Variable Frequency Drive (VFD) normally used?
