Cell Test Wizard
Cell Test Options
The Cell Test wizard executes either the Fiber-Optic Test or the Bridge Cell Test
depending on the value of the Type of Cell Test parameter. Selecting one of the Cell
Tests and proceeding to the next Wizard page sets the Type of Cell Test parameter to
the appropriate value.

Fiber-Optic Test
The Fiber-Optic Test verifies that the gate drive fiber-optics between the fiber-optic
interface board (IS200FOSA) and the IGBT gate driver boards (IS200IGDM) are
properly connected. The test does not provide any automated diagnostic information.
Verification of the fiber-optic connections is done by visual inspection of the LED
lighting sequence on the IGDM gate driver boards and is the responsibility of the
user. The correct lighting sequence is described in the Fiber-Optic Test help section.

Read all of the Fiber-Optic Test instructions in the Fiber-
Optic Test help section before running the test. The user must
be familiar with the correct LED lighting sequence in order to
determine if the fiber-optics are connected properly.

Bridge Cell Test
The Bridge Cell Test performs the following tests:
•
Short Circuit Detection Test verifies that there are no undesired conductive
paths within the inverter power bridge and the load connected to it.
•
Open Circuit Detection Test verifies that all of the expected conductive paths in
the inverter bridge are available and that the shunt feedbacks are valid.
•
Voltage Feedback Evaluation verifies that all the voltage feedbacks are being
measured correctly.
•
Dynamic Brake Cell Test performs a short circuit detection test, open circuit
detection test, and voltage feedback evaluation for the dynamic brake assembly.
Note The Dynamic Brake Cell Test is only performed if the drive includes the
dynamic brake option.
