!! Only for 802D: The reason for this procedure is that the backup time is exceeded. Make
sure that the required operating time of the control corresponds to the specifications in
your Installation & Start-up Guide. The current backup copy of the buffered memory has
been created by the last internal data backup via the "Save data" softkey on the HMI.
- NC not ready.
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
Start the control again.
Switch control OFF - ON.
Buffered memory of FFS restored from backup medium (potential loss of data!)
For PC-NC: A possible data integrity error was detected in the FFS memory during
power-up. The FFS memory was initialized with the last backup copy. Changes in the
FFS memory, which have been made since the last backup copy update, have been lost.
!! Only for PC-NC: Backup copies of the buffered memory are updated (on the hard disk)
every time the control is shut down normally.
- NC not ready.
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
Start the control again.
Switch control OFF - ON.
Normalizing machine data has been altered
The control uses internal physical units (mm, degrees, s, for paths, velocities, accelera-
tion, etc.). During programming or data storage, some of these values are input and out-
put using different units (rev./min., m/s2, etc.).
The conversion is carried out with the scaling factors that can be entered (system-specific
MD array 10230 SCALING_FACTORS USER_DEF[n] (n ... index number 0 - 10), when
the corresponding masking bit is set to "1".
If the masking bit is set to "0" then scaling takes place with the internal standard factors.
The following machine data influence the scaling of other MDs:
• 10220: SCALING_USER_DEF_MASK
• 10230: SCALING_FACTORS_USER_DEF
• 10240: SCALING_SYSTEM_IS_METRIC
• 10250: SCALING_VALUE_INCH
• 30300: IS_ROT_AX
If these data are modified, the NCK must be powered up again. Only then will the input of
dependent data be performed correctly.
- Alarm display.
Please inform the authorized personnel/service department. If the alarm has been dis-
played after downloading an MD file which is consistent within itself, then the download
operation must be repeated with a new NCK power-up. (The file contains scaling-depen-
dent machine data in front of the scaling factors).
Clear alarm with the Delete key or NC START.
Check absolute encoder position
A machine date has been changed influencing the value of an absolute encoder position.
Please check the position values.
