4065 Buffered memory was restored from backup medium (potential loss of

data!)

Definitions: A possible inconsistency 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. The reason for this proce-

dure 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

carried out via the "Save data" softkey on the HMI.

Reaction: NC not ready.

NC Start disable in this channel.

Interface signals are set.

Alarm display.

Remedy: Restart the control.

Program Con-

tinuation:

Switch control OFF - ON.

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.

Reaction: NC not ready.

NC Start disable in this channel.

Interface signals are set.

Alarm display.

Remedy: Start the control again.

Program Con-

tinuation:

Switch control OFF - ON.

4070 Normalizing machine data has been changed

Definitions: The control uses internal physical units (mm, degrees, s, for paths, velocities, acceleration, etc.). Dur-

ing programming or data storage, some of these values are input and output using different units

(rev./min, m/s2, etc.).

The conversion is carried out using scaling factors which can be entered (system-specific MD array

10230 SCALING_FACTORS USER_DEF[n] (n ... Index number 0 - 10) when the relevant 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:

MD 10220 SCALING_USER_DEF_MASK

MD 10230 SCALING_FACTORS_USER_DEF

MD 10240 SCALING_SYSTEM_IS_METRIC

MD 10250 SCALING_VALUE_INCH

MD 30300 IS_ROT_AX

After these data are changed, the NC must be restarted. Only then will the input of dependent data be

performed correctly.

Reaction: Alarm display.

Remedy: Please inform the authorized personnel/service department.

If the alarm has been displayed after downloading an MD file which is consistent within itself, then the

download operation must be repeated with a new NC power-up. (The file contains scaling-dependent

machine data in front of the scaling factors).

Program Con-

tinuation:

Clear alarm with the Delete key or NC START.

4071 Check the position of the encoder

Definitions: A machine data that affects the position of an absolute encoder has been changed. Please check the

position values.

Reaction: Alarm display.

Remedy: Please inform the authorized personnel/service department.
