10. Start up procedure for battery-less absolute encoder
10.1 Procedure for start up
Procedure for start up of the battery-less absolute encoder for every occasion when the power is applied.
* For the procedure for turning on the power with the incremental encoder, please refer to "11 Operation
instruction (1) Power on to origin return".
10.1.1 When power is supplied for the first time (Refer to 10.2 for details)
In the following cases, Alarm No.10-153 "Absolute encoder ID does not match controller data" is generated
after the power is applied, so perform the return to origin operation after resetting the alarm.
In addition, "When power is supplied for the first time" indicates the following cases.
• When connecting the electric actuator and turning on the power for the first time after purchase.
• When the actuator or motor has been replaced.
• When replacing the controller.
If the electric actuator and controller have been purchased as a set part number, the alarm may not be
generated by the customer because the alarm No. 01-153 "Absolute encoder ID does not match controller
data" is reset at the factory.
(If multiple units are purchased with the same set part number, alarm No. 01-153 "Absolute encoder ID
does not match controller data" will occur depending on the combination of the connected electric actuator
and controller.)
10.1.2 When the power is supplied again (Refer to 10.3 for details)
10.1.3 Alarm (group E) is cleared by a cut to the power supply (Refer to 10.4 for details).
SETON output is turned OFF. Perform return to origin operation.
When the power is applied again after changing Return to origin parameter "Return to Origin Direction",
follow the same start up procedure.
