Step mode operation can be used to extend the operating time in certain ranges or for the
whole travel; it is available in local, remote and emergency mode.

Cycle start, cycle end, cycle duration and interval time can be set separately for both
directions. (see Figure 55)

function.
Speed adaption is activated. The speed is reduced
according to the runtime and pause time in the step
mode range. (Example: Running time 1 sec and
pause time 1 sec results in half the speed). If the
1:
minimum speed is undershot, the actuator clocks in
the converted ratio with the minimum speed. The
speed adjustment is only applicable to actuators of
the type CM and AB CSC.
