The Dedrive Pro performs under even the most arduous conditions.

The load – positioned with millimetre accuracy – can be fed through the openings in the walls.

Suitable for any operating environment “Direct Torque Control” enables the Dedrive Pro to implement a wide variety of highly dynamic operating sequences. The entire output capacity of the drive can be utilised. The drive control system ensures that process sequences remain smooth, precise and reliable, even under arduous operating conditions. You can choose: Variable speed at constant torque ... The is the right solution if the application requires variable travel, lifting, turning and slewing motions, regardless of the given load. Exact torque control provides a constant torque, even at low frequencies. This means that drives always start smoothly and offer unmatched precision controlled braking. This solution not only offers reliable protection for the loads to be transported, but also ensures the safety of the installation.

... or variable torque at constant speed This control variant enables a constant speed to be maintained, even if the load fluctuates widely. The torque is exactly adapted to the given load for the specific speed setting. In this way, the required performance level of an installation is achieved at all times and under all operating conditions. This is decisive in the case of machinery when product quality depends on a constant speed. In these applications, Dedrive Pro satisfies all requirements with the integrated speed and fast torque control. Thanks to its short drive control rise time, Dedrive Pro responds very quickly to changes in load or external factors such as wind forces acting on cranes outdoors, for example.
