Abs posn data lost

Details
The absolute position data has been lost. An error of the multi-rotation counter data in the detector and so on
may be the cause. (Liquid penetrates into encoder connector, etc.)
Remedy
Replace the detector and complete zero point initialization.
(Note) To release alarm "Z70 Abs data error", enter the parameter data output when establishing the absolute
position and turn ON the power again. For the rotary axis, however, the alarm cannot be released by
