At SPS, STÖBER presents the new SB6 drive controller, suitable for 1-4 axis applications for small and medium-sized businesses. The new standalone solution combines numerous functions in a space-saving unit. The control effort is significantly reduced. Thanks to its compact dimensions, it fits into control cabinets with an installation depth of just 210 mm. On request, STÖBER can equip the SB6 with a control unit. All safety functions are available up to SIL 3 PL e (Cat. 4). Both linear and rotary synchronous servo, lean and asynchronous motors can be controlled. The use of an SD card as application memory simplifies commissioning – just insert it into the SB6. Another special feature is the number of digital and analog inputs and outputs. This STOBER drive controller therefore offers a full range of functions.
In Nuremberg, visitors will also have the opportunity to get to know the proven sixth generation SC6 and SI6 drive controllers. The SC6 is a compact, standalone controller with a nominal output current of up to 19 A for up to two drive axes. The SI6 is also slim and dynamic and with a nominal output current of up to 50 A, it is suitable for multi-axis drives. It allows economical solution of four or more axes, e.g. in packaging systems. In cooperation with Pilz GmbH, STÖBER has developed the SX6 safety module for both controls, which, true to the motto “Safety at a Level”, raises the safety level to a new level. The control can be used in safety-related applications up to SIL 3, PL e (category 4) according to DIN 61800-5-2 or DIN EN ISO 13849-1. STOBER has especially revised the switch-off channel for the Safe Torque Off (STO) stop function. With 20 ms, it is now even faster than competitors on the market. The short worst-case reaction time allows the safety distance to be minimized. The SX6 module also offers the option to automate commissioning with an optional SD card.
Also on display is the KS bevel gearbox, of which STÖBER offers both single and two-stage versions, true to its motto of “power without compromise”. The series is characterised by robust bearing technology and high-quality gears, which make KS gearboxes extremely resilient and resistant to tipping over. Compared to the two-stage version, the single-stage version allows for a significantly higher output speed and a wide gear ratio range of 200-400. The gearbox can also be mounted directly on a range of STOBER engines. Thanks to the space-saving drive, designers benefit from reduced weight, increased torque and therefore increased power density. Eliminating the motor adapter results in a lower moment of inertia for the gearbox, which makes it possible to make the most of the drive dynamics.
STÖBER also introduces a newly developed rack with twice the number of mounting holes: there are now threaded holes every 62.5 millimeters instead of the usual every 125 millimeters. This doubles the contact pressure of the component against the machine body. Pinning is not necessary, but is possible thanks to existing holes. This increases safety and maximizes installation comfort.
In addition, the drive specialist is working with Siemens to demonstrate full connectivity with Siemens’ motion solutions using the digital twin. To enable implementation even in complex applications, STÖBER supports drive connection via PROFIdrive and with PROFIsafe. The model includes various components from the drive specialist, such as bevel and planetary gear motors as well as drive controllers from the SC6 and SI6 series. Siemens provided the CAD data as well as the software required for the real-life simulation, which is shown on a separate display.
