TRACTION MOTOR INVERTER

Inspection and Adjustment


INSPECTION AFTER INSTALLATION

After installing traction motor inverter, measure resistance below.
- Between traction motor inverter (aluminum part) and DC/DC-J/B (aluminum part).
- Between traction motor inverter (aluminum part) (A) and body (ground bolt) (B).











Standard: Less than 0.1 Ohm

If result deviates from standard values, check that no paint, oil, dirt, or other substance is adhering to bolts or conductive mounting parts. If any such substance is adhering, clean the surrounding area and remove the substance.

ADJUSTMENT AFTER INSTALLATION

It is necessary to perform writing of the traction motor resolver offset to the traction motor inverter after the traction motor inverter is replaced. Work Procedure.
