9 Diagnostics & error management
This chapter provides information on error handling, drive diagnostics, and fault analysis.
9.1 Basics on error handling in the controller
Many of the functions integrated into the controller can
 detect errors and thus protect the device from damage or overload, e.g. short-circuit
detection, Ixt overload detection, overtemperature detection, etc.
 detect an operating error by the user, e.g. a missing memory module, a required or
missing communication module, etc.
 output a warning signal if desired, e.g. if the speed is too high or too low, etc.
Depending on the importance, the error detection in the device responds very fast (e.g.
short-circuit detection < 1 ms) or in a slower cycle (e.g. temperature monitoring approx.
100 ms).
All functions provided with an error detection (e.g. the motor control) supply information
to a so-called error handler. The error handler is processed every 1 ms and evaluates all
information.
In this evaluation, the so-called status determining error (display in C00168) and the
current error (display in C00170) are generated, and the controller is caused to take the
respective error status (e.g. TroubleQSP).
These two types of error information serve to diagnose errors systematically and contain
the following information:
1. The error type (e.g. "Warning")
2. The error subject area (e.g. "CAN generally integrated")
3. The error ID within the error subject area
Together all types of information form the real error number which is unique in the whole
device system.
In addition to the control of the device status by the error handler, a logbook function
records the errors and their histories.

Tip!
For many device errors, the error type and hence the response of the controller to
the error can be parameterised.
