Encoder interface
The universal encoder interface offers a wide range of possibilities for the acquisition of angles, positions and
pulses to be counted.
The following encoders can be connected:
Inkremental encoder with RS422 interface (RS422)
Inkremental encoder with 5V single ended interface (TTL)
Inkremental encoder with 24V single ended interface (HTL)
SSI- Encoder
EnDat 2.1 single turn encoder
EnDat 2.1 multi turn encoder
These encoders can be mixed as required. The module also provides the supply voltage for 5V encoders
with a maximum of 150mA per encoder. This is monitored and an error is signalled if it is exceeded.
The encoder interface can also be used as an event counter and record 6 fast signals. In this case no
encoder can be connected.
In the following chapters you will find an overview of the configuration options with the associated objects.
These are linked to the object directory.
