10.1.3 Warning Displays
Warning display, names, and meanings are shown in table 10.2.
Note: 1. The following warnings are not detected when Pn008 = n. 1 (Does not Detect a Warning).
A.900, A.901, A.910, A.911, A.920, A.930, A.941
2. A.94 , A.95 , and A.96 warnings are not detected depending on the warning check mask
(Pn800.1) settings.
A.94 and A.95 warnings are detected for default settings.
Table 10.2 Warning Displays and Outputs
Warning
Display
Warning Name Meaning
A.900 Position Error Pulse Overflow Position error pulse exceeded the parameter settings (Pn520 ×Pn51E/100).
A.901 Position Error Pulse Overflow
at Servo ON When the servo turns ON, the position error pulses exceeded the parameter
setting (Pn526
×Pn528/100).
A.910 Overload This warning occurs before the overload alarms (A.710 or A.720) occur. If
the warning is ignored and operation continues, an overload alarm may
occur.
A.911 Vibration Abnormal vibration at the motor speed was detected. The detection level is
the same as A.520. Set whether to output an alarm or warning by “Vibration
Detection Switch” of Pn310.
A.920 Regenerative Overload This warning occurs before the regenerative overload alarm (A.320) occurs.
If the warning is ignored and operation continues, a regenerative overload
alarm may occur.
A.930 Absolute Encoder Battery
Voltage Lowered This warning occurs when the absolute encoder battery voltage is lowered.
Continuing the operation in this status may cause an alarm.
A.941 Change of Parameters
Requires Setting Validation The change of the parameters can be validated only after turning the power
ON from OFF.
A.94A Data Setting Warning 1
(Parameter Number Error) Incorrect command parameter number was set.
A.94B Data Setting Warning 2
(Out of Range) Command input data is out of range.
A.94C Data Setting Warning 3
(Calculation Error) Calculation error was detected.
A.94D Data Setting Warning 4
(Parameter Size) Data size does not match.
A.95A Command Warning 1 Command was sent though command sending condition was not satisfied.
A.95B Command Warning 2 Unsupported command was sent.
A.95C Command Warning 3 Command condition is not satisfied for parameter settings.
A.95D Command Warning 4 Command, especially latch command, interferes.
A.95E Command Warning 5 Subcommand and main command interfere.
A.960 MECHATROLINK
Communications Warning Communications error occurred during MECHATROLINK
communications.
