Control Techniques announces new servo drive
19 March 2018
Control Techniques, part of the Nidec group of companies, has revealed its new generation of advanced servo drive technologies.
The new Unidrive M750 series (0.7 Nm – 51 Nm with 153 Nm peak/1.5 A – 16 A with 48 A peak) delivers ultimate motor control performance and flexibility, from a 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.
Unidrive M753 is designed as an optimised amplifier for high performance centralised control with EtherCAT integrated on-board and simple rotary switches for fast network address assignment.
Alternatively, the flexible Unidrive 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 decentralised machine control.
Minimum size
For both single and multi-axis configurations, the Unidrive M750 series offers compactness – the M753 EtherCAT variant is just 40mm wide – that is 5 axes across the width of this A4 piece of paper with 10mm spare, or 7 axes if you turn it to landscape. The drive is also designed to fit within shallow 200mm cabinets.
Its patented Ultraflow system allows machine builders to further reduce cabinet size by up to 50 percent 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.
Maximum performance
High dynamic applications will benefit immensely from Unidrive M750’s 300 percent peak performance pulse-duty overload capabilities, along with its 62 µs current loop and 16kHz 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.
Quick and easy installation
Unidrive M750 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.
Flexibility
The Unidrive M750 servo series flexibly adapts to your architecture of choice, be it centralised motion control, distributed intelligence, or any combination of the two. Support for all main industrial field-buses guarantees easy integration into any production line.
Complementary motor line-up
Working in tandem with the Unidrive M750 series, Control Techniques’ Unimotor hd is a high dynamic AC brushless servo motor delivering high performance.
With a wide torque range, from 0.72 Nm up to 85 Nm with 255 Nm peak, rated speeds from 1,000 to 6,000 rpm, several inertia levels and a broad selection of feedback options, Unimotor hd offers the perfect fit for high dynamic applications.
