The Compax3 machine zero modes are adapted to the CANopen profile for Motion
Control CiADS402.
Essentially, you can select between operation with or without machine reference.
The reference point for positioning is determined by using the machine reference
and the machine reference offset.
Machine reference run
In a homing run the drive normally moves to the position value 0 immediately after
finding the home switch. The position value 0 is defined via the homing offset.
A machine reference run is required each time after turning on the system for ope-
ration with machine reference.
Please note:
During homing run the software end limits are not monitored.
Positioning after homing run
The positioning made after the home switch has been found can be switched off.
For this enter in the "machine zero" window in the configuration wizard "no" under
"approach MN point after MN run".
Example Homing mode 20 (Home on homing switch) with T40 by homing
offset 0
With positioning after homing run The motor stands then on 0:
