∗1. Use Pn008.2 to activate or not the warning detection.
∗2. Use Pn008.1 to activate or not the warning detection.
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 overload alarm may occur.
Abnormal vibration at the motor speed was detected. The detection level is the same as
A.520. Set whether to output an alarm or warning by the vibration detection switch
(Pn310).
This warning occurs before the regenerative overload alarm (A.320) occurs. If the
warning is ignored and operation continues, a regenerative overload alarm may occur.
This warning occurs before dynamic brake overload alarm (A.731) occurs. If the warn-
ing is ignored and operation continues, a dynamic brake overload alarm may occur.
This warning occurs when the voltage of absolute encoder's battery is lowered.
This warning occurs when there is an error in a parameter number sent to the SERVO-
PACK from the host controller or command option module.
This warning occurs when out-of-range data is sent to the SERVOPACK from the host
controller or command option module.
This warning occurs when there is an error in the parameter data sent to in the SERVO-
PACK 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 SER-
VOPACK 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 operation execution conditions in the SERVOPACK
have not been met.
This warning occurs when there is an error in the reference output from the command
option module to the SERVOPACK.
This warning occurs when a latch command is output from the command option mod-
ule to the SERVOPACK during latch operation.
This warning occurs when an unallowed command combination is output to the SER-
VOPACK from the command option module.
This warning occurs when there is an error in the command output to the SERVO-
PACK from the command option module.
This warning occurs when an error occurred in communications between the SERVO-
PACK and command option module.
This warning occurs before undervoltage alarm (A.410) occurs. If the warning is
ignored and operation continues, an undervoltage alarm may occur.
Overtravel is detected while the servomotor power is ON.
