The above example clearly shows that there are two monitoring functions acting independently of
each other. Normally, one following error monitoring function with a low tolerance is set as
warning, and the other with a higher tolerance is set as TroubleQuickStop.
By means of the waiting times (C1244/2 and C1244/3), the error responses can be delayed, so that
disconnection does not result immediately when the following error limits are temporarily
exceeded. This "switch-on delay" makes it possible to effectively distinguish between dynamic
processes and actual error states such as mechanical obstacles or sluggishness.
Example of the evaluation of the following error
Target position Limit for following error monitoring 1 (C01215/1)
Position actual value Limit for following error monitoring 2 (C01215/2)
Current following error Waiting time for following error monitoring 1 (C01244/2)
Waiting time for following error monitoring 2 (C01244/3)
