**** A safety level can only be achieved in these cases, if it is physically ensured that
there only can be only one direction of rotary and linear movement. This can be realized for
example by using a self-locking gearbox.
This mode (only DS23x) allows to evaluate a dual channel system, equipped with two different
encoder types. Therefor a combination of a SinCos encoder and an incremental single channel HTL
encoder is used. The SinCos encoder must be performed in accordance to chapter
5.3 and the
incremental encoder to chapter 5.5 .

In this operational mode a DS230 variant reproduces always the input frequency at
[X6 | SINCOS IN 1] to the splitter output [X5 | SINCOS OUT].
 A DS230 variant reproduces selectively the input frequency of Sensor1 or Sensor2 to the
splitter output [X4 | RS422 OUT].

The inputs at [X7 | SINCOS IN 2], [X8 | RS422 IN 1] and [X9 | RS422 IN 2] have no function.

When connecting the HTL encoder to terminal [X10] pin 4 and 5, the Control2 input is no
more available. In this case only the Control1 input can be used.
