B&R offers servo drives with safety function Safely Limited Torque
The B&R ACOPOS P3 servo drive is now also available with safety function Safely Limited Torque (SLT). This makes B&R one of the first manufacturers to offer this certified safety function. Safely Limited Torque safely monitors torque up to SIL 2 / PL d.
The torque is limited to the configured maximum value with the aid of current measurement integrated directly in the drive system. Since the safety function runs decentrally in the drive, an extremely short maximum fault detection time of 8 ms is guaranteed. Particularly when combined with other safety functions such as Safely Limited Speed or Safe Direction, the SLT function facilitates safe collaboration between human operators and their machines. The risk of operators being injured via pinching or crushing while working on a machine is minimized.
Safe prevention of mechanical overload
SLT can also be used to safely limit the load on mechanical systems. In this way, the safety function acts like a torque wrench that prevents over-tightening of screws. SLT can therefore be used as a protective measure against overloading drive axes and brakes. As a result, it is possible to use less expensive mechanical components since there is no need to account for torque spikes.

Cables and wires in industrial robots and other moving machine parts are often required to withstand extreme stresses caused by torsion. Constant repetitive movements put materials under considerable strain. At the same time, operators expect components to function perfectly and reliably throughout their entire service life to avoid disruptions, outages and safety hazards.
For this reason, at HELUKABEL, we simulate intensive and continuous torsion stresses under realistic conditions with our high-tech testing equipment in Windsbach. We have several types of apparatus for doing this because some of our customers, for example those in the automotive industry, have very precise specifications for how a torsion test is carried out. The tests show that our cables and wires withstand speeds up to 1,000°/s, accelerations up to 2,000°/s² and torsion angles up to 720°. Hence, we make sure that each product always meets our customers’ high standards, and that they receive the impeccable quality they rightly expect from us as a leading supplier of cables, wires and accessories for more than 40 years.
