Dunkermotoren improves functional safety15 April 2021

Just a few decades ago, fast-rotating saws without guarding or goods transport according to the principle ‘size has right of way’ were common. Today, even working alongside powerful collaborative robots is safer than with a capricious desktop stapler.

The reason for this is functional safety, which systematically helps to avoid danger through many standards. In the future, Dunkermotoren drives in the 20-3,900W range will also be available with functional safety, thus contributing to safer products.

All motors and external controllers with dPro functionality can be integrate STO (Safe Torque Off). In combination with Industrial Ethernet, STO will become standard, without affecting their size.

Where energy-hungry and space-consuming mechanical relays are currently still used, fully-integrated

electronic circuits in Dunkermotoren controllers ensure that motors are switched reliably and torque-free in accordance with relevant standards when required.

Since the logic voltage is maintained when STO is triggered, the time-consuming process of referencing after restart is also eliminated. Therefore, a high degree of safety is achieved with a high degree of efficiency, the company concludes.
