Warning Name
Position error exceeded the parameter setting (Pn520×Pn51E/100).
When the servomotor power is ON, the position error exceeded the parame-
ter setting (Pn526×Pn528/100).
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.
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 the vibra-
tion detection switch (Pn310).
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.
This warning occurs before dynamic brake overload alarm (A.731) occurs. If
the warning is ignored and operation continues, a dynamic brake overload
alarm may occur.
This warning occurs when the voltage of absolute encoder's battery is lowered.
Command input data is out of range.
Calculation error was detected.
Data size does not match.
Latch mode error is detected.
Command was sent although the conditions for sending a command were not
satisfied.
Unsupported command was sent.
Command, especially latch command, interferes.
Subcommand and main command interfere.
Undefined command was sent.
Communications error occurred during MECHATROLINK communications.
This warning occurs before undervoltage alarm (A.410) occurs. If the warn-
ing is ignored and operation continues, an undervoltage alarm may occur.
Overtravel is detected while the servomotor power is ON.
