Alarm Name
The overtravel signal was detected at polarity detection.
The linear servomotor was turned ON under the condition of
polarity detection uncompleted.
The movement distance exceeded the set value of Pn48E
during polarity detection.
The polarity detection failed.
The data of the absolute linear scale was not properly cleared
or set.
Communications between the SERVOPACK and the linear
scale is not possible.
A linear scale position data calculation error occurred.
An error occurs in the communications timer between the
linear scale and the SERVOPACK.
Linear scale parameters are faulty.
Contents of communications with linear scale is incorrect.
Reception from the feedback option module is faulty.
Timer for communications with the feedback option module
is faulty.
Position error pulses exceeded the value set for parameter
(Pn520) (Excessive Position Error Alarm Level).
Position error pulses accumulated too much.
After a position error pulse has been input, Pn584 limits the
speed if the servo ON command is received. If Pn584 limits
the speed in such a state, this alarm occurs when the position
references are input and the number of position error pulses
exceeds the value set for parameter Pn520 (Excessive Posi-
tion Error Alarm Level).
The position feedback data exceeded ±1879048192.
Communications initialization failed between the SERVO-
PACK and the command option module.
A synchronization error occurred between the SERVOPACK
and the command option module.
An error occurred in the data of communications between
the SERVOPACK and the command option module.
An error occurred in establishing communications (settings)
between the SERVOPACK and the command option mod-
ule.
A error occurred in synchronization between the SERVO-
PACK and the command option module.
A error occurred in establishing communications between
the SERVOPACK and the command option module.
A error occurred in communications between the SERVO-
PACK and the command option module.
There was a change in timing of synchronization between
the SERVOPACK and the command option module.
Detection of the command option module failed.
Detection of the safety option module failed.
