U580 Control word for commutation monitoring
(2580)
The commutation of the converter is constantly monitored. If a commutation
failure is detected, fault message F030 is activated and the thyristor is
quenched by the SIMOREG CCP (if installed).
Detection of a commutation failure is based on three decision criteria. They
can be individually activated/deactivated with this parameter for test
purposes.
0: None of the three decision criteria are evaluated
1: Decision criterion 1 (sufficient voltage time area for
commutation) is evaluated
2: Decision criterion 2 (curvature of the current crest curve) is
evaluated
4: Decision criterion 3 (maximum current actual value) is evaluated
Setting instruction:
Each decision criterion has a numeric code.
If more than one decision criterion is to be evaluated, the sum of the
relevant digits must be entered.
U581 Diagnostic memory for commutation monitoring
(2581)
This memory is updated every time fault message F030 is activated.
It provides the SIEMENS specialist with more detailed information about the
cause of the commutation failure.
U582 Reaction of commutation monitor
(2582)
This parameter allows the reaction of the commutation monitor to be
programmed.
1 Detection of a commutation failure or overcurrent results in
immediate pulse blocking and generation of warning A030. The
pulses are enabled again after approximately 20ms and warning
A030 is reset.
2 Detection of a commutation failure or overcurrent results in
immediate pulse blocking and generation of fault message
F030.
Important:
The setting U582 = 1 is not allowed when the SIMOREG CCP is selected
(P790 = 6)!
