56 8 Rotational speed / angle
difference, encoder 1 - 2
Cause:
Rotational speed difference
between encoder 1 and 2 of one µC
outside the permissible range for
longer than the allowed time.
Angle difference between encoder 1
and 2 of one µC outside the
permissible range for longer than
the allowed time.
Action:
Problem may occur if two position
encoders are used in the system
and they are not “rigidly coupled”.
Check for elasticity or looseness,
improve mechanical system.
Adjust the expert parameters for the
position comparison if this is
acceptable from an application point
of view.
9 Error, cross-comparison of
encoder analysis
Cause: Cross-comparison between µC1 and
µC2 has detected an angle difference
or rotational speed difference or
difference in capture times for the
position encoders.
Action: Timing disrupted. If the error occurs
again after a reset, the safety module is
presumably faulty.
