Defining the analog input function - example

Signal smoothing
When required, you can smooth the signal, which you read-in via an analog input, using
parameter p0753.
For more information, see the parameter list and in the function block diagrams 9566 ff of the
List Manual.
Specify deadband
Small signals of a few millivolts are often corrupted by interference in the cable. To be able
to enter a setpoint of exactly 0 V via an analog input, you must specify a deadband.

Running the motor in jog mode (JOG function)
The "Jog" function is typically used to slowly move a machine part, e.g. a conveyor belt.
With the "Jog" function, you switch the motor on and off using a digital input. When the motor
is switched on, it accelerates to the jogging setpoint. There are two different setpoints
available, e.g. for motor counter-clockwise rotation and clockwise rotation.
The same ramp-function generator acts on the setpoint as for the ON/OFF1 command.

In order to use the analog input AI 0 as the source for
the supplementary setpoint, you have to set
p1075 = 755[0].
