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.
