By daisy-chaining multiple controllers, the number of axes to be controlled can be freely scaled. The various devices are quickly and easily connected to each other and to their central PS6 power supply module using Quick DC-Link modules. Available as a single- or dual-axis controller, it has a nominal output current of up to 50 amps.
In more dynamic applications requiring high power, such as metal or wood machining or presses, increased power is also needed due to the greater number of axes. In response to this demand, STOBER has launched the PS6 High Power decentralized power supply unit, which allows designers to use a single power module to supply multiple axes with higher power. The rated current is 95 amps, while the rated voltage across the axes is 50 kilowatts. For processes with high starting torque and dynamic ramps, it offers 150% overload for five seconds or 120% for 30 seconds.
With the SI6 drive controller in combination with the new power module, EZ-type synchronous servomotors, for example, can be controlled. The new One Cable Solution (OCS) reliably connects the motor to the controller at a distance of up to 100 meters. This means only a single hybrid cable is needed for the simultaneous transmission of electrical power and encoder data—a task that typically requires two cables. Its key feature is interference-free signal transmission at distances of up to 50 meters without the need for costly and bulky chokes. STOBER developed this hybrid cable in collaboration with HEIDENHAIN. Consequently, for the encoder interface, STOBER relies on the new, future-proof HEIDENHAIN EnDat® 3 protocol. This single-cable solution is optimized for dynamic applications in drag chains and is suitable for space-constrained environments. The user thus obtains from STOBER a complete and highly dynamic system consisting of the motor, cable, and drive controller, including a powerful power module.
Another advantage: the PS6 High Power module is UL certified and therefore meets the requirements for the US market.
