Following error monitoring system

The difference between set position and actual position is called the following error.
Ideally, the following error should be "0". The set position is created by the internal
definition of the traversing profiles of the Motion Control Kernel. The actual position is
created by the integration of the speed supplied by the position encoder. If the position
control is adjusted optimally, only a mininum following error arises which is always
compensated dynamically and not increases continuously.
Certain processes, however, require that a defined limit as a difference between set
position and actual position is not exceeded. If it is exceeded, it may have been caused by
a mechanical blocking in the machine and the system part is not situated at the position
defined at that time. In such a case, it makes sense to activate the "Fault" error response to
make the motor torqueless.
In the 8400 HighLine controller, two independent following error monitoring systems can
be parameterised:

Note!
If the limit for the following error is set to "0.0000 units" (Lenze setting, the
following error monitoring system is not active.
