Axis 1
Alarm
(SVRDY “ON”)
Abnormal
(SVRDY “OFF”) Classifies failures into “alarm” or “abnormal” according to
the value of “IW††00 + axis offset.” Check for the follow-
ing errors.
• Alarm
Deviation error
Parameter setting error
• Abnormal
Fixed parameter setting error
Absolute encoder I/F error

Operation of
other CPU
stops Indicates other Modules that do not operate. For example,
CPU Module is in STOP status.
Absolute posi-
tion reading
retry status Indicates retrying of absolute position reading by turning ON
the power and resetting from the start, in the case of setting
absolute encoder for fixed parameter encoder.
