3.4 Analogue/Digital Inputs
3.4.1 Configuration of Inputs
The three analogue/digital inputs of the EKE10-0070-5E-IM are based on the same hardware
and can be configured as analogue or digital input.
The following functions can be configured:
•
Analogue speed set point
•
Enable (START/STOP)
•
Activate fixed speed set points
•
Manipulate speed set point by a percent value
•
Touch function (digital speed set point)
– “Speed UP” and “Speed DOWN”
•
Reset errors
3.4.1.1 Programming of Input Function
Note
All inputs will
always
be added together to calculate the speed set point.
nΣ:
added speed set point values from other inputs

Table 13: Bit assignment Config_ADIN register 40023
Default setting:
ADIN1:
Analogue input (register value=0)
ADIN2:
Input deactivated
(register value =15)
ADIN3:
Input deactivated
(register value =15)
Note
In case more than one inputs are configured as Enable, all of this inputs are
linked with AND. To start the motor all of this inputs need to be activated
(HIGH).
