10.5.12.4 Interface Signals And Machine Data - Siemens SINUMERIK 804D sl Commissioning Manual

NCK start-up
10.5 Parameterize axis data
Notice
The status of the absolute encoder is only automatically reset to 1 = "encoder not
calibrated" by the NCK on gear change:
• MD34210 $MA_ENC_REFP_STATE[n] = 1
In all other cases, it is the sole responsibility of the NCK user to indicate the uncalibrated
state of the absolute value encoder by manually resetting the status to "encoder not
calibrated" and to perform calibration again.
