Altivar Machine variable frequency drives from Schneider Electric

Variable frequency drives can be found in the Drive technology category and are often an integral part of automation architecture, as they control the speed of electrical motors. The ultra-modern technology makes it possible to vary the frequency of the electrical supply and thus flexibly adjust the speed of the motor to suit the respective requirement. Within an industrial context, this is particularly relevant with a view to increasing the efficiency of processes and to simultaneously optimise energy costs and extend the service life of machines.

Function and areas of application of variable frequency drives

The areas of application for variable frequency drives span several different industrial sectors. From conveyor belts to pumps, or from fans to production machinery: variable frequency drives are used in all areas in which the precise control of the speed is required. By adjusting the motor output to suit the actual requirement, companies can not only make energy savings, but also extend the lifespan of their systems.

The precise control that variable frequency drives offer contributes to increasing accuracy in industrial processes. This is of crucial importance, especially in production environments in which precise processes and hiqh quality standards are required. On the whole, variable frequency drives are therefore an essential component in order to optimise the output of machines and systems, while simultaneously making more efficient use of operating resources.

Below, Automation24 presents the three different Altivar Machine Variable Frequency Drives from Schneider Electric in greater detail, thus helping you to make the right choice for your processes and systems!

The Altivar Machine ATV12 Variable Frequency Drive is the first choice for simple applications

The series of Altivar 12 variable frequency drives are single-phase variable frequency drives for simple applications. Depending on the model, they have a power output ranging from 0.18 to 2.2 kW and are perfect for commercial consumers and small machines with 3-phase 230 V asynchronous motors requiring an EMC standard of up to class C1 in residential areas.

The variable frequency drives are equipped with 3 macro-applications; Start/Stop, PID, and Speed, for simple applications. In addition, they offer integrated PID, PID feedback monitoring, PID speed prediction, a simple jog function, Catch on the fly, and 8 preset speeds.

The design of the Altivar Machine ATV12, which has a strong focus on integration, offers a fantastic way to upgrade simple machines and make them even more competitive. On account of its wide range of functions, such as the integrated PID control and frequency presets, the productivity of systems is significantly increased. These intelligent features enable the precise control and adjustment of machine performance, with a view to optimally fulfilling the respective requirements.

Effortless communication with other systems is made possible by the integrated serial Modbus interface. This seamless networking facilitates the integration of various components and enables efficient interaction between the individual elements of a system.

Optimal embedding into any grid network is guaranteed by the low leakage current, integrated EMC filter, which is compliant with EN 61800-3 Category C1. This not only ensures a reliable and secure output, but also fulfils the highest of standards with regard to electromagnetic compatibility.

Overall, the Altivar 12 offers an innovative solution with which to optimise the performance of machines and meet the requirements of modern industrial environments.

The Altivar Machine ATV320 is the robust variable frequency drive for mechanical engineering

The series of Altivar 320 variable frequency drives is a variable frequency drive developed especially for mechanical engineering, with integrated safety functions and enhanced communication possibilities in various model sizes. It thus fulfils both simple and expanded application requirements for 3-phase synchronous and asynchronous motors from 0.18 kW to 15 kW.

Here, the Altivar ATV320 variable frequency drive gives particular consideration to the progressive digitalisation of production processes, which increasingly render it necessary for various solutions to offer compatibility with hybrid automation systems. Solid construction standards and a host of international certifications thus ensure simple instalation and seamless integration into existing systems. As such, installation costs are lowered and machine performance enhanced, while the lifecycle of a system can also be extended in relation to installation and maintenance.

The Altivar ATV320 is available in two formats: the book format is particularly narrow and can fit into cramped control cabins or machines that are set on an angle, while the compact format features a square design and takes up very little room in different machine layouts. In addition, the robust design of the product is underscored by the IEC 60721-3 Class 3C3-certified coated PCBs. This increases the availability of the system, especially under challenging ambient conditions. Consequently, temperatures of 50°C without a performance reduction (debating) and 60°C with a performance reduction are possible, without the need for additional cooling.

The enhanced connectivity of the system enables smooth integration into a host of the most common Ethernet and serial communication networks, from EtherNet/IP to CANopen. This versatility guarantees seamless integration into existing systems and promotes efficient communication between different components.

The ATV320 Variable Frequency Drive also offers integrated safety functions, including Safe Torque Off (STO) and four other safety monitoring functions (SLS, SS1, SMS, GDL). These features simplify the certification process for machines and support adherence to Machinery Directive 2006/42/EC. As a result, not only is performance optimised, but the most demanding of safety standards are also observed. Overall, this makes the ALtivar ATV320 a reliable and advanced solution to the challenges posed by modern industrial applications.
