Temperature Monitoring; Dc Link Voltage Failure - Siemens SINAMICS G150 Reference Manual

Tests
3.2 Function test
Test procedure
1. The auxiliary voltage is present.
2. The drive is in operation.
3. The button is pressed.
Result
The test is passed if the drive is switched off in accordance with the category that was ordered
– and the appropriate message is displayed on the test station computer.
3.2.9

Temperature monitoring

Fundamentals
Depending on the version and application, the temperature thresholds differ for alarm and fault.
Further, in operation, the drive continually recalculates the temperature thresholds. This is the
reason that predefined temperature thresholds cannot be specified in the report, as only actual
values are documented.
Test procedure
1. The auxiliary voltage is present.
2. The switching thresholds at the temperature sensor inputs are triggered.
3. The actual values for alarm and fault are documented.
Result
The test is passed if the appropriate messages are displayed on the test station computer.
3.2.10

DC link voltage failure

Fundamentals
The drive shuts down if the DC link voltage fails. DC link voltage failure is simulated by switching
off the supply.
