Siemens SINAMICS G150 - Sensing the Actual DC Link Voltage; Switching Thresholds of the Optional Temperature Evaluation Device; Safety Shutdown (Optional)

3.2.6 Sensing the actual DC link voltage
Fundamentals
The DC link voltage actual value sensing is tested.
Test procedure
1. The DC link is charged up to the rated voltage.
2. The actual value sensing devices in the drive measure the voltage.
The DC link voltage is displayed at the test station computer in the appropriate parameters.
Result
The test is passed if the displayed value at the test station computer matches the reference
value.
3.2.7 Switching thresholds of the optional temperature evaluation device
Fundamentals
The switching thresholds of the temperature monitoring function are checked.
Test procedure
1. The auxiliary voltage is present.
2. The switching thresholds at the temperature sensor inputs are triggered.
The following messages are displayed on the test station computer:
– T
1
: Alarm
– T
2
: Fault
Result
The test is passed if the appropriate messages are displayed on the test station computer. The
tolerance range at the switching thresholds is ±5 K.
3.2.8 Safety shutdown (optional)
Fundamentals
The tests are performed according to IEC 60146-1-1 and IEC 60204-11. The safety shutdown
of the power section is tested according to the category that was ordered.
