drive controller

High-efficiency drive controllers with safety technology.

Whether for high-performance systems, highly efficient multi-axis applications or compact modules – the 6th generation from STOBER always has the right drive controller on hand.

Benefit from four series of our drive controllers that can be combined with each other: SC6 for compact systems, the slim and dynamic SI6 for multi-axis drive systems, the flexible SD6 for all kinds of tasks, and the new, universal SB6 for a variety of applications.

BENEFITS

Every drive solution has its own unique character. And we have the matching drive controllers!
Whether drive-based or control-based – we have universal and flexible solutions for any kind of motion control.

The shortest possible recovery times from fast set value changes and load jumps are the reason why our drives have such high dynamics.
There is also an option of connecting the drive controllers in a DC link for multi-axis applications, which improves the energy footprint of the entire system.

And speaking of energy, all STOBER drive controllers comply with energy efficiency class IE2 in accordance with EN 61800-9-2.


The SC6 series is ideal for combination with the innovative STOBER Lean motor – for example, for energy-efficient transport systems. Another benefit is that the Lean motor and SC6 run completely without an encoder!


The most striking feature is its extremely compact design! With a width of only 45 mm, the SI6 requires extremely little space in the control cabinet.

Each SI6 is connected to a central PS6 supply module. Additional fuses and cabling for each individual axis are not required. This reduces the space and costs.

The STOBER SI6 drive controller also offers a lot for acceleration: Together with an EZ series synchronous servo motor, it can go from 0 to 3000 rpm in 10 ms.


Controlling servo axes precisely and quickly is its game. Due to its high computing power, the SD6 recalculates the position, speed and torque control of the servo axes every 62.5 μs. This enables extraordinarily high dynamics and precision for the drives with very short recovery times and also fast reactions to set value changes and load jumps.

The modular interface concept of the new SB6 drive controller enables versatile system designs. This allows mechanical engineers to react flexibly to customer requirements. As a stand-alone device with an integrated power supply, it is ideal for drive-based motion tasks.

The SB6 is available as a single-axis controller in three sizes with a nominal output current of up to 32 A. It is suitable for machines with up to four axes as well as for controlling synchronous servo motors and Lean motors.

For connection to a higher-level control system, firmware-based EtherCAT and Profinet are available. The drive controller can also be extended by safety standards STO and SS1 via Fail Safe over EtherCAT (FSoE) and PROFIsafe up to SIL 3, PL e, category 4.
