**** 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) is used to evaluate a dual channel system, equipped by two different
incremental encoder resp. sensor types. Therefore an incremental RS422/TTL encoder and a single-
channel HTL encoder are used. The RS422/TTL encoder must be performed in accordance to chapter
5.4 and the HTL encoder to chapter 5.5 .

A DS230 variant reproduces selectively the input frequency of Sensor1 or Sensor2
to the splitter output [X4 | RS422 OUT].

The inputs at [X6 | SINCOS IN 1], [X7 | SINCOS IN 2] und [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.
