"The trend towards decentralized drive electronics is continuing," explains Jörg Niermann, Head of Marketing at the Nord-Drivesystems Group. "Drive-related assembly directly in the system field is very attractive, especially in logistics with its often extensive systems as well as in modular and mobile systems." Another current topic is specialization: "Inverters are being developed for applications such as certain logistics areas, for example Warehouse and Post & Parcel, which are increasingly tailored to precisely these applications. But technical improvements such as multi-protocol Ethernet interfaces, multi-encoder interfaces for multi-axis operation, USB interfaces for voltage-free parameterization or improved motor control are also increasingly in focus at the moment."

These are precisely the special functional features of the universal frequency inverter series "Nordac Pro SK 500P", whose power range Nord Drivesystems is now expanding upwards with the five power levels 7.5, 11, 15, 18.5 and 22 kW. While the 7.5 and 11 kW power levels will be available in four equipment variants, with the basic version already covering a wide range of possible applications, the 15, 18.5 and 22 kW power levels will only be available on the market as advanced versions with optional modules for interface expansion. Compared to the control cabinet inverters in the "Nordac Pro SK 500E" series, this results in a reduction in the number of device variants with a larger and even higher-quality range of functions.

Nord Drivesystems is expanding its "Nordac Pro SK 500P" frequency inverter family by five power levels. The available power levels are spread across five sizes.

The frequency inverters have a modular design and offer an integrated PLC for drive-related functions. The PLC processes the data from connected analog and digital sensors and actuators (e.g. from light barriers, temperature sensors or vibration sensors) as well as position reached messages from the internal positioning function and can initiate sequence controls autonomously.

According to Nord Drivesystems, the individual device variants can be easily assigned to the requirements of specific applications. Plug-in operating, safety and option modules ensure flexibility, and the compact design in booksize format enables space-saving installation in the control cabinet. Even in the basic version, the members of the "Nordac Pro SK 500P" device family offer connection and functional features such as CANopen interface, brake chopper, four parameter sets, PLC function and "Posicon" positioning control.

The new sizes of the "Nordac Pro SK 500P" will be available from spring 2022. The inverter family will then cover the power range from 0.25 to 22 kW. The new generation of inverters adopts the "Nordac" parameter structure and is physically and functionally backwards compatible. The family will be successively expanded so that all power ranges of the "Nordac-Pro" devices will be equipped with the appropriate technology in the coming years.
