However, the following warnings are not affected by the setting of Pn008 = n.X and other parameter
settings are required in addition to Pn008 = n.X.
Warning Parameters That Must Be Set to Select Warning Detection
A.911 Pn310 = n.X (Vibration Detection Setting)
A.930 Pn008 = n.X (Low Battery Voltage Alarm/Warning Selection)

A.971
(Not affected by the setting of Pn008 = n.X.)
Pn00D = n.X (Overtravel Warning Detection Selection)
A.9A0
(Not affected by the setting of Pn008 = n.X.)
A.9b0 Pn00F = n.X (Preventative Maintenance Selection)
Meaning
The input voltage (temperature) for the overheat
protection input (TH) signal exceeded the setting of
Pn61C (Overheat Warning Level).
The speed ripple compensation information stored
in the encoder does not agree with the speed ripple
compensation information stored in the SERVO-
PACK.
This warning occurs before an A.410 alarm (Under-
voltage) occurs. If the warning is ignored and oper-
ation is continued, an alarm may occur.
Overtravel was detected while the servo was ON.
One of the consumable parts has reached the end
of its service life.
A warning occurred in the INDEXER.
