error pulses 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 overload 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 "Vibration Detection Switch" of Pn310.
This warning occurs before the regenerative overload alarm
(A.320) occurs. If the warning is ignored and operation contin-
ues, a regenerative overload alarm may occur.
This warning occurs before Dynamic Brake Overload (A.731)
alarm occurs. If the warning is ignored and operation continues,
a dynamic brake overload alarm may occur.
This warning occurs when there is an error in a parameter num-
ber sent to the SERVOPACK from the host controller or
command option module.
This warning occurs when out-of-range data is sent to the SER-
VOPACK from the host controller or command option module.
This warning occurs when there is an error in the parameter data
sent to in the SERVOPACK from the host controller or
command option module.
This warning occurs when there is an error in the data size sent
to the SERVOPACK from the host controller or command
option module.
This warning occurs when there is an error in the latch mode
settings sent to the SERVOPACK from the host controller or
command option module.
This warning occurs when the host controller or command
option module outputs an operating command when the opera-
tion execution conditions in the SERVOPACK have not been
met.
This warning occurs when there is an error in the reference out-
put from the command option module to the SERVOPACK.
This warning occurs when a latch command is output from the
command option module to the SERVOPACK during latch
operation.
This warning occurs when an unallowed command combination
is output to the SERVOPACK from the command option mod-
ule.
This warning occurs when there is an error in the command out-
put to the SERVOPACK from the command option module.
