Test procedure
1. The drive is switched on.
2. The drive is switched off and grounded according to the following scheme.
Action Switching states

Result
The test is passed if the corresponding switching states occur.
3.2.19 Failure of a power semiconductor module
Fundamentals
The power section must shut down if a power semiconductor module fails. The failure is
simulated by withdrawing the fiber-optic cable connector from the gating module of a power
semiconductor module. This interrupts the control.
Test procedure
1. The auxiliary voltage is present.
2. The fiber-optic cable connector of a gating module is withdrawn.
A message is displayed on the test station computer.
