Maintenance
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
Overload
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
Battery Error
This warning occurs when the voltage of absolute
encoder’s battery is low.
LLH
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.
