Normalizing machine data has been changed
Explanation:
The control uses internal physical units (mm, degrees, s, for paths, velocities, acceleration, etc.). During 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 with the scaling factors that can be entered (system-spefic MD array MD10230
$MN_SCALING_FACTORS_USER_DEF 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:
MD10220: $MN_SCALING_USER_DEF_MASK
MD10230: $MN_SCALING_FACTORS_USER_DEF
MD10240: $MN_SCALING_SYSTEM_IS_METRIC
MD10250: $MN_SCALING_VALUE_INCH
MD30300: $MA_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.
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).
Programm
continuation:
Clear alarm with the Delete key or NC START.

Check the position of the encoder
Explanation:
A machine data has been changed that affects the value of an absolute encoder position. Please check the postion values.
For absolute encoders:
Encoder adjustment has been changed, the machine reference of the axis position may have changed, check the encoder
adjustment.
Other encoders:
The reference point of the axis position has been changed, check the referencing procedure.
A machine data was changed that influences the position value of an absolute encoder. Please check the position values.
Reaction:
Alarm display.
Remedy:
Please inform the authorized personnel/service department.
Programm
continuation:
Clear alarm with the Delete key or NC START.

Machine data %1 (and maybe others) not changed due to missing permission level %2
Parameters:
%1 = String: MD identifier
%2 = Write protection level of the MD
Explanation:
On executing a TOA file or when writing machine data from the part program, an attempt has been made to write an item
of data with a higher protection level than the access authorization currently set in the control. The item of data in question
has not been written and program execution is continued. This alarm is set only when access violation is detected for the
first time.
On executing a TOA file or when writing machine data from the part program, an attempt has been made to write an item
of data with a higher protection level than the access authorization currently set in the control.
The item of data in question has not been written.
This alarm is set only when access violation is detected for the first time.
Reaction:
Alarm display.
Remedy:
Please inform the authorized personnel/service department. Set the required access level by means of keyswitch or
password entry or delete the machine data concerned from the MD file/part program.
When entering a password, set the required access level or delete the corresponding machine data from the MD file.
Programm
continuation:
Clear alarm with the Delete key or NC START.
