4.4.2.1 Motor Identification Plate

Stegmann and Heidenhain encoders provide the option of storing OEM data in their
EEPROM. This memory is used to store the following information in the encoders:
m Notch angle offset
m Machine characteristics
m Encoder characteristics
m Motor ordering code
The data structure of the OEM memory follows the Baumüller standard, as already imple-
mented on the b maXX 4400 and 5200/5300. Thus identification plates can also be read
from encoders which were previously used in b maXX 4400 and 5200/5300 drives and
conversely.
