Error type C:
This error type is signaled if an error counter (parameter 90...98) overflows
and internal error handling procedures are ineffective (see section 5.4.6).
In the case of an equipment fault, the same error will be signaled within a short
time of resetting the signal.
If a cold start (see section 5.4.8) does not solve the problem, please return the
unit to one of our authorized dealers, giving an exact description of the problem
and stating the error code (parameter 9).
