RESOLVER WRITE

Description

INFOID:0000000010120920

If the work listed below was performed, it is necessary to perform writing of the traction motor resolver offset to

the traction motor inverter.

• Replacement of traction motor

• Replacement of traction motor inverter

• Replacement of traction motor and traction motor inverter

Location of traction motor resolver offset stamp

NOTE:

Because the traction motor resolver offset stamp is located on the lower side of the traction motor, it is neces-

sary to remove the under cover in order to check it.

Work Procedure

INFOID:0000000010120921
