Warning Name
The position deviation exceeded the percentage set
with the following formula:
(Pn520 × Pn51E/100)
The position deviation when the servo was turned ON
exceeded the percentage set with the following formula:
(Pn526 × Pn528/100)
This warning occurs before an overload alarm (A.710 or
A.720) occurs. If the warning is ignored and operation is
continued, an alarm may occur.
Abnormal vibration was detected during motor opera-
tion. The detection level is the same as A.520. Set
whether to output an alarm or a warning by setting
Pn310 (Vibration Detection Selections).
The surrounding temperature of the control PCB is
abnormal.
The surrounding temperature of the power PCB is
abnormal.
