Setting write
protection for
memory areas
Third option (no screenshot):
Attention
Select Yes/No (check mark in check box = yes, check box empty = no).
When you have successfully edited the encoder configuration on your computer, you must
transfer it to the encoder.
Press
Only then will the data in the encoder memory be active.
(See “Save encoder configuration in encoder" on page 59.)
The old data will be overwritten.
We recommend that you back up the "old" encoder configuration!
For EnDat encoders there is the possibility of assigning a write-protection to the memory areas
so that the data are protected from unintended editing. This is necessary, particularly to ensure
machine safety and system reliability.
HEIDENHAIN therefore protects the ”parameters of encoder manufacturer” memory area with
the corresponding write-protection bit. Among other information the encoder adjustment data
are stored here; editing these data would render the encoder inoperable.
We recommend setting the appropriate write-protection bit after setting the machine-relevant
parameters in the OEM memory areas and after "datum shift" (operating parameters)!
Attention
The write-protection cannot be reset after the encoder configuration was saved in the
encoder.
Only JH Traunreut or an authorized HEIDENHAIN representation can cancel writeprotection!
Example: Setting write-protection
means "YES" = Write-protection set.
When you click this button the data is transferred to the encoder memory and
write-protection is active.
