F → 4 → 8: General illegal instruction interruption
occurrence
F → 4 → 9: Slot illegal instruction interruption
occurrence
F → 5 → 0: CPU address error interruption occur-
rence
F → 5 → 1: DMA address error interruption occur-
rence
F → 5 → 2: User brake interruption occurrence
F → 5 → 3: Trap instruction interruption occurrence

Axis 1
Alarm
(SVRDY “ON”)
Abnormal
(SVRDY “OFF”) Classifies the failure into “alarm” or “abnormal”
according to the “IW††00 + axis offset contents.
Verify that the following error occurs.
• Alarm
Deviation error
Parameter setting error
• Abnormal
Fixed parameter setting error
Absolute encoder I/F error
Axis 2
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 param-
eter encoder.
