Multi-axis servodrive is ‘most competitive’ up to 750W
Published:  21 April, 2022

Trio Motion Technology used the recent Drives & Controls Show to launch a multi-axis servodrive designed to provide precision motion coordination for space-critical applications up to 750W. The DX5 servodrive is aimed at machine-builders who need multi-axis EtherCat control in a compact format with no gaps between the drives.

The drive is suitable for 2-16-axis applications such as laser, plasma or water cutting. It can also be used for packaging applications including form-fill-seal and labelling.

“The DX5 multi-axis servodrive is for machine-builders who need high-performance motion synchronisation in a lower power, compact and cost-effective package,” says Trio’s president, Tom Alexander. “The multi-axis system provides high speed and precision EtherCat motion control, offering what we believe is the most price-competitive multi-axis servo package up to 750W.”

The drives’ multi-axis synchronisation capabilities include EtherCat control down to 250μs, with 350% overload for pulse duty cycles. The drives also support 20-bit single-turn or 23-bit multi-turn absolute encoders, allowing precision high-speed control with multi-axis coordination for high throughput and production quality.

The servodrives are designed as space-saving dual-axis modules in 400W and 750W frame sizes. They can be combined to offer up to 16 400W axes or eight 750W axes with no stacking gaps, thus minimising footprints. A dual-axis module measures 40 x 205 x 203mm. Eight 750W axes including their power stage occupy a width of 240mm, while 16 400W axes are 400mm wide, making the DX5 among the smallest multi-axis servo systems available. The 750W drive supports 400W and 750W servomotors, while the 400W drive supports 100W, 200W and 400W servomotors.

A regenerative DC bus system absorbs motor braking energy, allowing it to be re-used across the machine’s axes.

Cost savings are achieved by removing I/O from the individual drive axes, and integrating them instead into a Trio Motion Coordinator. This achieves one of the lowest cost-per-axis counts in the market, according to Trio.

Trio claims that its new DX5 servodrive is one of the smallest on the market

When used with the company’s matching low-inertia, high-speed MXL servomotors, plug-and-play operation is possible.

Trio’s free Motion Perfect PC tool allows fast auto-configuration, while seamless integration with Trio’s quick-to-program controllers ensures trouble-free machine set-ups.

There is a choice of programming languages between IEC 61131-3, PLCopen and Trio’s text-based Motion-iX language. Extra control functions can be added using Trio’s Flexslice I/O system with modules that click into place.
