Monitoring and protective functions
9.5.1
Protecting power components
Description
SINAMICS power units offer comprehensive functions for protecting power components.
Table 9-12 General protection for power units
Protection against:
Protective measure
Response
Monitoring with two thresholds:
•
First threshold exceeded
A30031, A30032, A30033
Current limiting in phase U has responded.
Pulsing in this phase is inhibited for one pulse period.
F30017 -> OFF2 is triggered if the threshold is
exceeded too often.
Overcurrent
1)
•
Second threshold exceeded
F30001 "Overcurrent" -> OFF2
Overvoltage
1)
Comparison of DC link voltage with
hardware shutdown threshold
F30002 "Overvoltage" -> OFF2
Undervoltage
1)
Comparison of DC link voltage with
hardware shutdown threshold
F30003 "Undervoltage" -> OFF2
Short-circuit
1)
Second monitoring threshold checked
for overcurrent
Uce monitoring for IGBT module
F30001 "Overcurrent" -> OFF2
F30022 "Monitoring Uce" -> OFF2
Ground fault
Monitoring the sum of all phase
currents
After threshold in p0287 is exceeded:
F30021 "power unit: Ground fault" -> OFF2
Note:
The sum of all phase currents is displayed in r0069[6].
For operation, the value in p0287[1] must be greater
than the sum of the phase currents when the
insulation is intact.
Line phase-failure
detection
1)
F30011 "Line phase-failure in main circuit" -> OFF2
1)
The monitoring thresholds are permanently set in the converter and cannot be changed by
the user.
