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

Meaning
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 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.
Some kind of error has occurred at the INDEXER
Module.*
