5.3. Error handling
Many functions integrated in the inverter can
• detect errors and thus protect inverter and motor from damages,
• detect an operating error of the user,
• output a warning or information if desired.
5.3.1. Error types
In the event of an error, the inverter response is determined by the error type defined for
the error.
In the following, the different error types are described.
Error type "No response"
The error is completely ignored (does not affect the running process).
Error type "Warning"
A warning does not severely affect the process and may be also ignored in consideration
of safety aspects.
Error type "Fault"
The motor is brought to a standstill with the quick stop ramp.
•
The inverter will only be disabled after the quick stop is executed (motor at standstill)
or after the time-out time set in 0x2826 has been elapsed.

Exception:
In case of a serious fault, the inverter is disabled immediately. The motor
becomes torqueless (coasts). For details see the table "Error codes".
454
Error type "Trouble"
Just like "Fault", but the error state will be left automatically if the error condition is not
active anymore.
•
Exception:
In case of a severe trouble, the inverter is disabled immediately. The motor
becomes torqueless (coasts). For details see the table "Error codes".

•
The restart behaviour after trouble can be configured.
Automatic restart

In the operating mode 0x6060 (P301.00) = "CiA: Velocity mode [2]", the behaviour in
case of "Trouble" is just like in case of "Fault"!
