Defining the digital signals for controlling referencing
Procedure
To define the digital signals for controlling, proceed as follows:
1. This signal starts the reference point approach.
2. This signal must be 0 for the reference point approach.
3. Interconnect the signal of the reference cam with the corresponding signal of your
machine.
4. If you use the reversing cam minus, interconnect the reversing cam with the
corresponding signal, e.g. with the fieldbus.
0 = Reversing cams active.
5. If you use the reversing cam plus, interconnect the reversing cam with the corresponding
signal, e.g. with the fieldbus.
0 = Reversing cams active.
You have now defined the digital signals for controlling.
Defining the analog signals for controlling referencing
Procedure
To define the analog signals for controlling, proceed as follows:
1. Define the signal source for the velocity override.
See also section: Direct setpoint input (MDI) (Page 203).
2. Change the source for the reference point coordinate, if necessary.
You have now defined the analog signals for controlling.
