For Automatic Adjustment Failure
The circuit in which failure occurred can be traced to some
degree by the trouble message displayed together when the
message “Auto Adjust Failure” is displayed during execu-
tion of Servo System adjustment menus.
n
The trouble message display indicates that no adjustment
could be performed because the circuit described in this
manual did not operate normally. Moreover, other circuits
(e.g., control signal system) in which failure actually
occurred may also exist.
