Warning Name
Position error exceeded the parameter setting
(Pn520×Pn51E/100).
When the servomotor power is ON, the position error exceeded
the parameter 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 over-
load alarm may occur.
Abnormal vibration at the motor speed was detected. The detec-
tion level is the same as A.520. Set whether to output an alarm or
warning by the vibration detection switch (Pn310).
This warning occurs when the voltage of absolute encoder's bat-
tery is lowered.
Parameters that require the restart have been changed.
Overtravel is detected while the servomotor power is ON.
