Electronic Id Labels - HEIDENHAIN TNC 410 M Technical Manual

2.1.2 Electronic ID Labels

2 – 4
All inverter components of type D, as well as new motors with EnDat
interface, are equipped with electronic ID labels which ensure automatic
recognition and integration of these components by the control. When the
control is first started, it already recognizes the motors, inverters and power
supply units in the system and adapts the machine parameters automatically
to the respective requirements. Each further time the control starts up, the
data are read out again and compared to the entries in the machine
parameters.
This data is stored in the electronic ID labels:
Designation of unit
Part number (ID)
Serial number (SN)
