NOTE
When performing maintenance such as replacement of a
wire harness in the manipulator, the encoder connector may
be necessary to be removed. In this case, be sure to con-
nect the battery pack to the battery backup connector
before removing the encoder connector. Removing the
encoder connector without connecting the battery pack
leads to disappearance of the encoder absolute data.
For the battery pack connection, refer to
