Stopping time and machine diagnosis
Why measure stopping time?
— to find out which safety arrangements can be used in a certain area around a machine, and where they should be located.
Stopping time
The safety distance (how far away from the risk area a safety component must be placed) is based upon the machines stopping time. The basic idea is that a safety component should be placed so far from the risk area that it is not possible to enter the area before the machine has stopped.
Stopping distance
For safety contact strips it is extra important that the stopping distance is monitored. An incorrect stopping distance could in many cases result in very high risks. The stopping distance is also needed during area limiting e.g. for robots when dividing the working area into sectors.
Regulations and standards
It is also important to measure the stopping time, to meet the requirements set by the machinery standards, directives and regulations.
Annual checks
Wear in a machine is something that can affect braking and motors, which means that the stopping time of a machine can change with time.
