Trio Motion Technology has updated its DX3 EtherCAT servo drives with Safe Torque Off (STO) functional safety to meet safety levels SIL3 and PLe. The motion specialist increases voltage to 480V on both the DX3 EtherCAT model and additional DX3 classic models, supporting pulse and direction, analog and CANopen control.
The DX3 series of single-axis servo drives offers machine builders greater design flexibility in a cost-optimized package. Both DX3 models are available in 200V versions that extend power from 50W to 2kW, and in new 480V versions with power ranges from 1kW to 7.5kW.
The servo drive range builds on Trio’s motion performance specialisation, including update rates as low as 125μs on the DX3 EtherCAT model, and is supported by a range of operating modes covering a wide range of use cases.
The servo drive performance is well within a compact footprint, ranging from 40mm wide, 172mm high and 180mm deep for the 50W drive, to 90mm wide, 260mm high and 230mm deep for the 7.5 kW version. The DX3 also features zero stacking gaps that allow flush mounting in a cabinet or DIN rail.
The flexible, high-performance servo drive ensures a cost-optimized location thanks to Trio’s “everything you need, nothing more” approach to drive design. Critical I/O remains, such as two touch probe inputs and general digital inputs and outputs that can be configured for specific drive functions.
To increase the long-term user value and reliability of the machine, the servo drive also features a range of electrical protection features, including: B. Overcurrent. Protected by IP20 housing.
The DX3 optimizes performance and allows for quick and reliable set-up. It also offers plug-and-play commissioning with Trio servo motors with electronic nameplate technology. Trio’s servo motors include the low inertia MXL series and the medium inertia MXM series, both available with high-resolution 17-bit or 23-bit absolute encoders. Easy setup, including auto-tuning, is enabled by Trio’s easy-to-use MotionPerfect software, which allows the DX series servo drives to operate with third-party controllers.
Trio’s DX servo drive series also includes the powerful DX4 EtherCAT drive and the compact two-axis DX5. Trio’s MotionFast automation solutions are based on a series of powerful motion controllers capable of high-speed adjustment of up to 128 servo axes.
“The addition of functional safety to our DX3 flexible servo drive line was a response to machine builders seeking increased flexibility through an expanded voltage range up to 480V,” said Tom Alexander, president of Trio. “The mechanical engineering market continues to trend towards EtherCAT performance, but OEMs still see a demand for control modes such as pulse and direction, so the DX3 servo drives offer this flexibility across an extended performance range. Cost optimization is particularly important for these sectors. However, there is a requirement to ensure fast and precise operation, and this is especially true for machines with a large number of axes, where values can be optimized.”
