Clearing Absolute Encoder
• Using a console
(1) Turn the power supply on and mount it to the machine when you find a position where a machine home
position and single-turn data of the absolute encoder become "0". (A position of single-turn data = "0" is
a position where the Z phase is output, only when the pulse output division ratio is "1:1".)
(2) After mounting it, turn it one quarter or one half turn counterclockwise. (If you perform clearing at a
position where the Z phase is output, the home position may turn completely in the worst case. Turn it
counterclockwise slightly from the Z phase output position when performing clearing.)
(3) Put the console in the auxiliary function mode and enable the EXECUTION display for "Absolute en-
coder clear mode". (Refer to "Absolute Encoder Clearing Function" in "Settings" on page 100.)

(4) Operate the key as shown below in the EXECUTION display.
When you keep on pressing
(approximately 3 seconds),
" " increases.
Absolute encoder clearing starts.
Clearing completes instantly.
Note: For the incremental encoder,
clearing is executed.
(5) Turn the power supply off once and turn it on again.
• Using the setup support software "PANATERM
Basically, the step (3) and (4) only are different from the procedure by the console. The absolute encoder
is cleared when you open the monitor window, select the [Absolute encoder] tab and press the [Clear]
button for the multi-turn data and encoder error. A digital value of single-turn data is shown on the same
monitor window. So, you do not need to check the Z phase as stated in 1).
