Control Techniques releases new servo drives

Control Techniques, part of the Nidec group of companies, has revealed its new generation of advanced servo drive technologies. The new Digitax HD servo series (0.7 Nm to 51 Nm with 153 Nm peak / 1.5 A to 16 A with 48 A peak) delivers ultimate motor control performance and flexibility in a uniquely compact package. Targeting high axis count automation systems, Unidrive M750 provides all of the benefits of a modular system with a common dc bus with standalone drive flexibility.

The new series is focused on high overload, pulse duty applications but also provides continuous servo control, plus induction motor control, and is initially available with two functionality levels. The new range is scheduled for UK launch in summer 2018.

Digitax M753 is designed as an optimized amplifier for high performance centralized control with EtherCAT integrated on-board and simple rotary switches for fast network address assignment. Alternatively, the flexible Digitax M751 Base option allows design engineers to add up to two option modules from the existing Unidrive M range such as PROFINET, Ethernet/IP or an IEC61131 high performance motion controller for decentralized machine control.

For both single and multi-axis configurations, the Digitax HD series offers compactness – the M753 EtherCAT variant is 40 mm wide. The drive is also designed to fit within shallow 200-mm cabinets.

Digitax HD, a compact 400-V servo drive, features the patented Ultraflow system that allows machine builders to further reduce cabinet size by up to 50% through expelling heat from the drive directly outside the cabinet. This approach offers the further benefit of enabling drives to be stacked without the need for a large air channel between them.

High dynamic applications will benefit from Digitax HD’s 300% peak performance pulse-duty overload capabilities, along with its 62 µsec current loop and 16 kHz switching frequency. Its flexible speed and position feedback interface supports a wide range of feedback technologies, from robust resolvers to the latest single cable digital encoder technologies.

Digitax HD boasts a wealth of features and accessories designed to make installation and commissioning as easy as possible. Features include easy-access pluggable connectors and a dedicated multi-axis paralleling kit for rapid installation; integrated braking resistor and electronic motor name plate for faster setup; and quick commissioning using the Unidrive M Connect PC tool, or an optional SD card. Machine Control Studio provides a flexible and intuitive IEC61131 environment for programming automation and motion control features.
