Meaning
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 Switch).
The surrounding temperature of the control PCB is
abnormal.
The surrounding temperature of the power PCB is
abnormal.
This warning occurs before an A.320 alarm (Regenera-
tive Overload) occurs. If the warning is ignored and
operation is continued, an alarm may occur.
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.
The fan inside the SERVOPACK stopped.
This warning occurs when the voltage of absolute
encoder's battery is low.
The input voltage (temperature) for the overheat protec-
tion input (TH) signal exceeded the setting of Pn61C
(Overheat Warning Level).
