Definitions: The user data saved in the flash memory are loaded to the SRAM.
Reactions: - Alarm display.
Remedy: Please inform the authorized personnel/service department. Load specific machine data
again.
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
4065
Buffered memory was restored from backup medium (potential loss of data!)
Definitions: Only occurs with PC-NC. A possible data integrity error was detected in the buffered
memory during power-up. The buffered memory was initialized with the last backup copy.
Changes in the buffered memory, which have been made since the last backup copy
update, have been lost. Backup copies of the buffered memory are updated (on the hard
disk) every time the control is shut down normally.
!! 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.
Reactions: - NC not ready.
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
Remedy: Start the control again.
Program Con- Switch control OFF - ON.
tinuation:
4066
Buffered memory of FFS restored from backup medium (potential loss of data!)
Definitions: 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.
Reactions: - NC not ready.
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
Remedy: Start the control again.
Program Con- Switch control OFF - ON.
tinuation:
4070
Normalizing machine data has been altered
Definitions: 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-spefic
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
