004E
(0078) Absolute rotation counter error
(ABS ROTA CNT ERR) An attempt was made to set the present position from the
absolute encoder, but the present position couldn’t be
defined due to the following reasons:
Rotation of the absolute encoder was beyond
±
99999.
Rotation of the absolute encoder was within
±
99998, but the
value with the correction value added exceeded the counter
value.
If the driver setup has not been completed yet, complete the
setup and try again.
If the driver setup has already been completed, shift the axis
to decrease the rotation of the absolute encoder and try
again.

004F
(0079) Absolute encoder error
(ABS ERR) Power was not supplied to the absolute encoder or the
absolute encoder was faulty.
Connect a battery to the absolute encoder.
If the battery has already been connected, the absolute
encoder may be faulty. Replace the absolute encoder.

(0082) Origin proximity and overtravel
simultaneously ON
(OR PRX AND OT ON) During an origin search, the origin proximity input signal and
the limit input signal in the direction of the search were both
ON at the same time.
Change the mounting positions of the origin proximity input
signal and limit input signal. Refer to
Appendix F Additional
Origin Search Patterns for details on how errors occur during
origin searches.
Deceleration
stop
0053
(0083) Overtravel always ON
(OVER TRAVEL ON) The limit input signal in the direction of the search was
already ON when a one direction-mode origin search was
executed.
Check the limit input signal in the initial origin search direc-
tion. Also check the location of the axis when the origin
search was started. Refer to
Appendix F Additional Origin
Search Patterns for details on how errors occur during origin
searches.
Deceleration
stop
0054
(0084) Origin proximity reverse error
(OR PRX REVROT ER) The reverse-mode origin search cannot be performed
because the limit input signal in the direction of the search
came ON while the search was reversing because of the ori-
gin proximity input. This is the same as when the origin prox-
imity input is also used as a limit input signal.
Check the limit input signal in the initial origin search direction
as well as the mounting positions of the origin proximity input
signal and limit input signal. Refer to
12. Reverse-mode Ori-
gin Searches, Number 12 in Appendix F for details on this
error.
Deceleration
stop
0055
(0085) Overtravel reverse error
(OT REV ROTAT ERR) The reverse-mode origin search cannot be performed
because the other limit input signal or the origin proximity
input signal came ON while the search was reversing
because of a limit input signal input.
Check the limit input signal in the initial origin search direction
as well as the mounting positions of the origin proximity input
signal and limit input signal. Refer to
12. Reverse-mode Ori-
gin Searches, Number 12 in Appendix F for details on this
error.
Deceleration
stop
0056
(0086) Wiring error
(WIRING ERROR) A wiring error was detected during the wiring check
automatically performed with the servo locked.
Check whether the number of pulses and check time in the
wiring check are correct. If they are correct, check whether
the encoder’s phase-A/phase-B wiring is correct. Refer to
page 132
Wiring Check .
