Dc-Link Pulsed Operation At 0 Hz; Dc-Link Pulsed Operation At 2 Hz - Siemens SINAMICS GL150 Reference Manual

Tests
3.2 Function test
Result
The test is passed if the drive responds as described above.
3.2.6

DC-link pulsed operation at 0 Hz

Fundamentals
The actual current values currently measured at the drive output at 0 Hz DC-link pulsing
frequency are displayed with reduced DC-link current with a short-circuited drive output on the
motor side.
Test procedure
1. The auxiliary voltage is present.
2. The rated voltage or a reduced voltage is applied to the rectifier input.
3. The DC-link pulsing frequency is set to 0 Hz.
4. The actual values of the input voltage and the DC-link current are displayed on the test
Result
The test is passed if direct current is flowing at the drive output.
3.2.7

DC-link pulsed operation at 2 Hz

Fundamentals
At a DC-link pulsed operation of 2 Hz, all of the inverter thyristors are controlled. The test is
performed with reduced DC-link current with a short-circuited drive output on the motor side.
Test procedure
1. The auxiliary voltage is present.
2. The rated voltage or a reduced voltage is applied to the rectifier input.
3. The DC-link pulsing frequency is set to 2 Hz.
Result
The test is passed if alternating current is flowing at the drive output.
