12 Technical data
Master frequency output X1
The connector X1 also accommodates the master frequency output (encoder emulation).
To use this function, X1 must be configured as the master frequency output.

The signals are generated based on the angle of rotation of the encoder with a freely
programmable line count.
In addition to the track signals A and B, the master frequency output also provides an
index pulse. Once per revolution, this index pulse turns high (for the programmed number
of lines) for half of a signal period.
Please also note that the track signals will not be automatically output with a constant
frequency. They may also be generated as so-called "pulse packets" depending on the
covered rotational angle of the source. This means that the interface for any downstream
circuits must be suitable for incremental encoders. As a result, the measurement of gate
times or the analysis of the time between two lines for determining a speed value is
possible only to a limited extent.
