STOBER has launched the new modular S16 Drive System, which, with a single centralised power supply, is the smallest Multi Axis Servo Drive available anywhere in the world!

The S16 is a modular and scalable Rack System for machine builders with multiple axes that will save costs in hardware, energy use and installation. The double axis module, which provides 2 x 5 amps, is just 45mm wide yet delivers a position, speed and current cycle time of only 62,5 µs.

Available in five sizes and with two power options, the new S16 saves both space and energy, and is so compact that a 20 axis system occupies a space of just <500mm. The integration of STOBER’s patented Quick DC-Link system using one bus voltage means that energy generated from one drive can be harnessed by the other modules, resulting in more power for less investment!

Martin Preece, managing director of STOBER Drives UK, explains: “Whilst the compact nature of the S16 is a big benefit, the omission of unnecessary power supplies is even more decisive.

The modular nature of the S16 means that the entire series of drive controllers can be connected by a central supply module, which negates the need for fuses and cabling on individual units. This means that power from one module is accelerated to the next module and so on.

“Consequently, STOBER’s new S16 gives engineers a significant reduction in both space and costs. For example, a width of 180mm is sufficient for a drive controller and supply module system with six axes. Additionally, double axis modules can also be combined with stand-alone units from the STOBER SD6 series, so regardless of whether you incorporate 4, 16 or 97 axes, capacity is precisely dimensioned.”

In terms of acceleration, the STOBER SI6 drive controller has plenty to offer. In combination with the STOBER synchronous EZ401 servo motor it accelerates from 0 to 3000 rpm in 10 ms and this interaction of drive controller, servo motor and encoder enables machine operators to make precise changes in speed to suit manufacturing requirements.

What’s more, the S16 is very quick and easy to fit, simply clicking into place with minimum wiring required.
