Stopping Angle and Time at the Emergency Stop
The definition of the coastdown times is important for determining the safety distance for
protective devices. The overrun time is the time that elapses from the point of time when
the stop signal is triggered until the robot comes to a complete stop. The overrun distance
is the angle that the robot travels from the point of time when the stop signal is triggered
until the robot comes to a complete stop.
The following diagrams show only the values for the S, L, and U axes since these axes have
the largest deflection. For a safety stop with stop category 0, the mean values determined
through testing and simulation are specified.
The actual overrun distances and overrun times may differ due to internal and external
influence on the braking torque. According to the mode, robot application, and number of
triggered safety stops with stop category 0, a different brake wear may occur. We
recommend that the coastdown path be checked once a year.
Fig. 6-7: Main axes at 100%, 66%, and 33% deflection
In Fig. 6-7: "Main axes at 100%, 66%, and 33% deflection" the S, L, and U axes are shown
at 33%, 66%, and 100% deflection according to DIN EN ISO 10218-1.
In these three positions, the coastdown paths and coastdown times were determined during
a safety stop with stop category 0 and stop category 1. In the following diagrams, they are
specified at payloads of 33%, 66%, and 100%.
