WARNING!
Users must take appropriate measures to detect or exclude
errors (e.g. slippage or broken shearpin) which cause the fre-
quency of the encoder signal to no longer be proportional to the
monitored speed.
Appropriate measures are:
Using the monitored encoder to also control the drive
Mechanical solutions
WARNING!
Encoder errors are detected and signalled via a diagnostic bit.
This does does not bring the relevant axis to a safe condition.
To maintain safety (Category 3), the diagnostic bit (diagnostic bit
10) in the user program must be evaluated in such a way that a
shutdown occurs if the axis is in operation (see examples in
Chapter 9).
