To reset the axis 3 encoder error, for instance, move the cursor to the [Err-df]
column on the [E3] line and press the [RESET] <F3> key. If everything is OK,
press the "EXE" key. Now the axis 3 encoder error has been reset.

Call the normal error screen, press the [RESET] <F3> key to reset the error of
"8–403 Axis3 Encoder Abnormal."
2.6.3 Multi-Turn Data Reset Operation
This operation should be executed after the home position of an appropriate axis has
been established, using the home point match-marks, that is, after the relevant axis has
returned to the home position.
As only the multi-turn data of the absolute encoder can be zero-reset and no single-turn
data is affected by this operation, the axis can be restored to a status which is quite the
same as the status prevailing before position error generation.
Also, as described above, the encoder error can be reset in lieu of the encoder error reset
operation.
•
When moving the robot by hand while the power is turned on, be sure to assure
the safe work and effect an emergency stop beforehand.
•
In the above situation, if the work is to be done while the axis 3 motor brake
OFF switch is pressed, be sure to perform the work by two (2) persons.
One person should carry out the work while the other is monitoring the work
outside the hazardous zone. The latter person should watch the work and be
ready to turn off the controller switch if any abnormality occurs. Once the
controller power is turned off, the motor brake actuates even if the axis 3 motor
brake OFF switch is kept pressed.
•
If the axis 3 motor brake OFF switch is pressed while the robot is carrying a
heavy workpiece, the axis 3 may drop suddenly. To avoid this, the customer
should take all necessary measures by themselves.
•
A misoperation of the multi-turn data reset can significantly affect the robot
current position. Therefore, the multi-turn data reset is always protected
against misoperation. Do not attempt to cancel the protection except when
operating the mutli-turn data reset.
