Configuration Configures the following properties of the "Axis" technology object:
• Selection of the analog drive connection or PROFIdrive to be used and configuration of the
drive and encoder interface
• Properties of the mechanics and the transmission ratio of the drive and encoder (or machine
or system)
• Properties for position limits, dynamics, and homing
Save the configuration in the data block of the technology object.
Commissioning Tests the function of your axis without having to create a user program. When the tool is started,
the control panel will be displayed. The following commands are available on the control panel:
• Enable and disable axis
• Move axis in jog mode
• Position axis in absolute and relative terms
• Home axis
• Acknowledge errors
The velocity and the acceleration / deceleration can be specified for the motion commands. The
control panel also shows the current axis status.
Monitors of the current status and error information for the axis and drive.
Note
You may have to adapt the values of the input parameters of motion control instructions t
