The evaluation of the electronic ID labels should be deactivated via MP7690 before exchanging
the rotary encoder inputs (motor encoder) or PWM outputs (interface to the power modules).
MP7690 Evaluation of the electronic ID labels
Input: %xx
Bit 0 – HEIDENHAIN power modules
0: Active
1: Inactive
Bit 1 – HEIDENHAIN synchronous motors
0: Active
1: Inactive
MPNAME.MP If the machine data are missing (data loss, replacement control, new control) the control opens
with the machine parameter "default setting" MPNAME.MP when booting the first time:
The file MPNAME.MP is generated by the HEIDENHAIN operating system.
The axes cannot be traversed, and the control is set to programming station.
The colors is set to the HEIDENHAIN standard colors.
There are no comments in MPNAME.MP.
Each parameter of the MPNAME.MP could now be set by the machine manufacturer.
In this case, the service engineer restores the backup of the machine data. --> See “Backup
on an External Data Medium” on page 13 – 192.
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 labels before.
If the control has already booted several times, the logo of the default setting appears in the
Power interrupted status. This is based on MPNAME.MP.
