12 Technical data
12.5 Encoder connector [X2B]
For the correct parameterisation of the multi-encoder interface, see section 7.5.3
"X2B/X6" tab on page 136.
The system does not support all of the encoders of a specific
manufacturer.
The system may not support all of the encoders of a specific manufacturer. This is why
the actual encoder should always be tested in the intended application prior to actually
using it.
Power supply output
The power supply for the encoders can be changed.
Risk of destruction due to excessive voltage
If the voltage is too high, the angle encoder may be destroyed. Ensure that you have
selected the correct supply voltage prior to connecting the encoder to the X2B
connector.
Characteristic Value A Value B
Output voltage 5.4 V 10.4 V
Output current 250 mA 200 mA
Short-circuit strength Yes Yes
Control via sense leads Yes Yes
Digital incremental encoders
Digital incremental encoders with RS422-compatible A/B/N signals with a line count of up
to 16,384 lines can be connected (e.g. ERN 420). In addition, Hall generator signals with a
TTL level for determining the commutation position can also be connected.
