Panasonic A4P Series instruction manual Clearing Absolute Encoder Using a console, 139

[Operation Setting]

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.)

Absolute encoder clearing starts.

Clearing completes instantly.

Note: For the incremental encoder, display appears when absolute encoder￿ clearing is executed.

(5)Turn the power supply off once and turn it on again.

•Using the setup support software “PANATERM®”

Setting Operation

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).
