4.4 Electrical
connections
The electrical connections are described below:
•
grouped according to numbers of the supply terminal strip (for exam-
ple, X1, X2 etc.)
•
and then according to the functions.
Serial interface X1
Maximum wire cross section which can be connected: 2.5 mm
2
At present, the serial interface does not offer any functions for the user.
The interface only offers developers of the unit diagnostic possibilities.
X2 external measuring system
maximum cable cross section which can be connected: 0.5 mm
2
This interface offers the option of connecting an external measuring sys-
tem directly mounted to the machine element. The measuring system can
be a rotary encoder as well as a linear encoder. Measuring systems with
sinusoidal output signals and a signal level of 1Vss (Heidenhain voltage
interface) can be connected.
Output voltage X2/12:
DC +5 V (± 5%)
max. load on the output X2/12:
150 mA
approximate sinussoidal signals
The signal period supplied by the measuring system is sampled 2048
times.
