Alarm reset
41B Absolute
encoder error
(1)
Cause:
[1] The power was turned on again when an absolute reset was
completed, or
[2] When an absolute reset is performed, an axis movement was
detected during a communication with the simple absolute unit
due to an external factor. The actuator may have moved due to
an external force, such as a reactive force of the self-supporting
cable, or there may be vibration at the installation location.
Action:
[1] Turn off the power once, and turn it back on while making sure
that there is no vibration on the actuator.
(Error list Info. 1 is 1.)
[2] Perform an absolute reset while making sure that there is no
vibration on the actuator.
(Error list Info. 1 is 2.)

41C Absolute
encoder error
(2)
Cause:
[1] The power was turned on for the first time after the battery was
connected.
[2] The battery voltage dropped to a level at which the encoder
counter data in the simple absolute unit could no longer be
retained.
A parameter relating to home return may have been changed.
(Error list Info. 1 is 1.)
[3] The encoder connector was removed during a power outage, or
the encoder cable was disconnected.
(Error list Info. 1 is 2.)
[4] The battery voltage dropped to 3.1 V.
(Error list Info. 1 is 4.)
[5] The battery is not connected.
(Error list Info. 1 is 5.)
Action:
Perform an absolute reset by following the absolute reset procedure.
When the battery voltage may have dropped as described in [2] or
the cause is [4], keep the power on for at least 48 hours to fully
charge the battery, and then perform an absolute reset.
* It takes 72 hours to fully charge the battery from when it is
uncharged.

41D Absolute
encoder error
(3)
Cause:
An axis movement was detected at a speed exceeding the setting
value specified in the rotation speed setting of the simple absolute
unit due to an external factor while the power was cut off.
Action:
Change the applicable setting on the simple absolute unit, or take
measures to prevent the axis from moving above the specified
speed while the power is cut off.
If the backup time is sufficient, increase the rotation speed setting.
When this error occurs, perform an absolute reset by following the
absolute reset procedure.
