Stober has launched the new modular SI6 drive system, which, with a single centralised power supply, is claimed to be the smallest multi-axis servo drive available. The SI6 is a modular and scalable rack system for machine builders with multiple axes that will save costs in 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.
