Meaning
The position deviation exceeded the parameter set-
tings (Pn520 × Pn51E/100).
The position deviation exceeded the parameter set-
tings (Pn526 × Pn528/100) when the servo was
turned ON.
The gap was 0 or lower during clearance control.
The difference between the clearance offset refer-
ence and gap exceeded Pn6F0 (Clearance Position
Deviation Overflow Level).
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
operation. The detection level is the same as A.520.
Set whether to output an alarm or a warning by set-
ting Pn310 (Vibration Detection Selection).
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 (Regen-
erative 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 speed ripple compensation information stored
in the encoder does not agree with the speed ripple
compensation information stored in the SERVO-
PACK.
There is an error in the parameter number for a Data
Setting Warning 1 (Parameter Number) command.
The command data is out of range.
A calculation error was detected.
