Specific shut-down of drives
Delay modules from DOLD allow the specific shut-down of the drives which reduces the risk of injury. A typical area of use are high-speed tools that continue to move after shut-down. Productivity is not affected as the machine can be immediately started again. The emergency stop of the dangerous movement can be accelerated through a specific shut-down in accordance with stop category 1 by allowing motor braking functions to be applied during the switch-off delay and/or the speed of the drive can be regulated.
