* Refer to the following sections for details.
15.3.3 INDEXER Module Error Displays and Troubleshooting
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.
A.912
Internal Temperature
Warning 1 (Control
Board Temperature
Error)
The surrounding temperature of the control PCB is
abnormal.
HLH
A.913
Internal Temperature
Warning 2 (Power
Board Temperature
Error)
The surrounding temperature of the power PCB is
abnormal.
A.920 Regenerative Overload
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.
A.921
Dynamic Brake Over-
load
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.
A.923
SERVOPACK Built-in
Fan Stopped
The fan inside the SERVOPACK stopped.
A.930
Absolute Encoder Bat-
tery Error
This warning occurs when the voltage of absolute
encoder’s battery is low.
LLH
A.93B Overheat Warning
The input voltage (temperature) for the overheat
protection input (TH) signal exceeded the setting of
Pn61C (Overheat Warning Level).
A.942
Speed Ripple Com-
pensation Information
Disagreement
The speed ripple compensation information stored
in the encoder does not agree with the speed ripple
compensation information stored in the SERVO-
PACK.
HHL
A.971 Undervoltage
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.
LLL
A.9A0 Overtravel Overtravel was detected while the servo was ON. H L L
A.9b0
Preventative Mainte-
nance Warning
One of the consumable parts has reached the end
of its service life.
HLH
A.A9F Error
Some kind of error has occurred at the INDEXER
Module.*
