17.5.1 Error types
In the event of an error, the inverter response is determined by the error type dened for the
error.
Error type "No response"
The error is completely ignored (does not aect the running process).
Error type "Warning"
A warning does not severely aect the process and may be also ignored in consideraon of
safety aspects.
Error type "Fault"
The motor is brought to a standsll with the quick stop ramp.
•
The inverter will only be disabled aer the quick stop is executed (motor at standsll) or
aer the me-out me set in 0x2826 has been elapsed. 4Timeout for error response

•
Excepon: In case of a serious fault, the inverter is disabled immediately. The motor
becomes torqueless (coasts). For details see the table "Error codes, causes and remedies".
Error type "Trouble"
Just like "Fault", but the error state will be le automacally if the error condion is not acve
anymore.
•
Excepon: In case of a severe trouble, the inverter is disabled immediately. The motor
becomes torqueless (coasts). For details see the table "Error codes, causes and remedies".

The restart behaviour aer trouble can be congured. 4Automac restart aer a
fault^ 512
In the operang mode 0x6060 (P301.00) = "CiA: Velocity mode [2]", the behav-
iour in case of "Trouble" is just like in case of "Fault"!
