A.9F9 INDEXER Warning
Note: 1. A warning code is not output unless you set Pn001 to n.1 (Output both alarm codes and warning
codes).
2. Use Pn008 = n.X (Warning Detection Selection) to control warning detection.
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.

The surrounding temperature of the control PCB is
abnormal.
The surrounding temperature of the power PCB is
abnormal.
This warning occurs before an A.320 alarm (Regen-
erative Overload) occurs. If the warning is ignored
and operation is continued, an alarm may occur.
This warning occurs before an A.731 alarm
(Dynamic Brake Overload) occurs. If the warning is
ignored and operation is continued, an alarm may
occur.
The fan inside the SERVOPACK stopped.
This warning occurs when the voltage of absolute
encoder's battery is low.
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.
Parameters That Must Be Set to Select Warning Detection
Pn310 = n.X (Vibration Detection Setting)
–
(Not affected by the setting of Pn008 = n.X.)
Pn008 = n.X (Low Battery Voltage Alarm/Warning Selection)
Pn423 = n.X (Speed Ripple Compensation Information Dis-
agreement Warning Detection Selection)
Pn008 = n.X (Low Battery Voltage Alarm/Warning Selection)
(Not affected by the setting of Pn008 = n.X.)
Pn00D = n.X (Overtravel Warning Detection Selection)
(Not affected by the setting of Pn008 = n.X.)
Pn00F = n.X (Preventative Maintenance Selection)
