10-2-4 Absolute Encoder Setup
You must set up the absolute encoder if using a motor with an absolute encoder. The setup is required
when you turn ON the power supply for the first time, when an Absolute Encoder System Down Error
(Error No. 40.0) occurs, or when the encoder cable is disconnected and then connected again.
To use an absolute encoder, set the Operation Switch when Using Absolute Encoder (3015 hex) to 0 or
2 (factory setting).
Refer to the CJ1W-NC281/NC481/NC881/NCF81/NC482/NC882 Position Control Unit Operation
Manual (Cat. No. W487) and to information on Absolute Encoder Setup (4102 hex) to set up the
absolute encoder.
Set up an absolute encoder while the servo is OFF. Always cycle the power supply after completing the
setup.
For information on setup using the CX-Drive, refer to “CX-Drive Operation Manual (W453-E1)” or
Setting Up an Absolute Encoder from the CX-Drive described below.
1
Start the CX-Drive and go online with the Servo Drive via EtherCAT or USB communications.
2
Select Absolute Encoder from the Tu n i n g Menu of the CX-Drive.
3
Select Multi-Turn Data and Encoder Error Clear from the Absolute Encoder Dialog Box.
The following error will occur after execution has been completed.
EtherCAT communications: Position Data Initialized (Error No. 27.7)
USB communications: Absolute Value Cleared (Error No. 27.1)
4
Turn the power supply to the Servo Drive OFF and then ON again.
