5 Functional Description of Inputs and Outputs
5.1 Inputs
5.1.1 Speed range and mode selection with «DigIN1» und «DigIN2»
The digital inputs «DigIN1» [11] and «DigIN2» [12] determine both, the ope-
ration mode (digital speed controller or digital speed actuator) and the speed
range in speed set value mode.

Please note
Ö
If the signal level of the digital inputs DigIN1 [
11
] and DigIN2 [
12
] are
changed, the new levels are adopted by a disable-enable procedure.
If the input «DigIN» is not connected (floating) or a voltage higher than 2.4 V
is applied, the input is active.
Logic 1
Input not connected (floating)
Input voltage > 2.4 V
Input active
If the input «DigIN» is set to ground potential or a voltage smaller than 0.8 V
is applied, the digital input is inactive
Logic 0
Input set to Gnd
Input voltage < 0.8 V
Input inactive
The inputs «DigIN1»and «DigIN2» are protected against over voltage.
