June 20, 2019 – B&R now offers its ACOPOS P3 servo drives with the safety function Safely Limited Torque (SLT).

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.

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.
