HEIDENHAIN iTNC 530 Service Manual page 416

Electronic ID label HEIDENHAIN inverter components of type D, as well as HEIDENHAIN synchronous motors with
absolute encoders with EnDat interface, are equipped with an electronic ID label.
The product name, the ID number and the serial number are saved in this ID label. These devices
are automatically detected when the control is started.
During every control restart, the control checks whether the connected units with electronic
ID label match the entries in MP2100.x or MP2200.x.
The evaluation of the electronic ID labels should be deactivated via MP7690 before exchanging
the rotary encoder inputs (motor encoder) of PWM outputs (interface to the power modules).
MP7690
Input:
26 – 416
Caution
If a unit with electronic ID label responds with the corresponding message window when
the control is restarted ...
The active MP list does not correspond to the connected unit
(e.g., if a backup was restored before that does not fit exactly to the machine).
The connected unit does not correspond to the active MP list
(e.g., the mounted replacement unit is not exactly the same).
You have exchanged the rotary encoder inputs or PWM outputs for troubleshooting,
without deactivating the evaluation of the electronic ID lables before.
