Absolute Encoder Setup
When the power is turned OFF, multi-turn data for the absolute value data will be retained using the
battery for the absolute encoder. Hence, when turning ON the machine for the first time after loading
the battery, you will need to clear the encoder at the origin and set the multi-turn data to 0. To clear
the encoder, use the Parameter Unit, CX-Drive or via MECHATROLINK-II.
Note Be sure to turn OFF and turn ON the control power supply again after clearing the absolute
value data. A command error (alarm code 27) will occur when the absolute encoder is
cleared from the Parameter Unit or CX-Drive. This is for safety purposes, not an indication of
failure. Note that the one-turn data cannot be cleared.
Absolute Encoder Setup Procedure (for the Parameter Unit)
1. Turn ON the power supply and align to the origin.
Turn ON the power supply, perform the origin alignment operation, and move the machine to the
origin position.
2. Go to Auxiliary Function Mode.
Press and on the Parameter Unit to display Auxiliary Function Mode.
3. Go to Absolute Encoder Clear Mode.
Press again. Absolute Encoder Clear Mode will be displayed.
