Command Table IO Interface
3 Smart Control Word Behavior
All control word actions, which are configured in the Command Table IO Interface, affect the
interface control word bits. So if a control word bit is mapped to a X4 IO or is forced by
parameter, this still has priority and the behavior rests unchanged.
3.1 Intf Switch On Flag Behavior
It is strongly recommended to influence the control word bit 0 'Switch On' over a serial bus
connection or a digital input. For a test system it might be helpful if the system starts up
automatically when switched on. For this case the switch on flag can be set to autostart.
3.2 Intf Home Flag Behavior
Setting the Intf Home Flag Behavior to 'Autohome' starts automatically the homing if the state
8 'Operation Enabled' is reached and the status word bit 11 'Homed' is cleared. When the
homing procedure has finished the interface control word bit 11 'Home' is cleared and the
state 8 is entered again.
3.3 Intf Error Acknowledge Flag Behavior
Setting the Intf Error Acknowledge Flag Behavior to '/Switch On Flag' sets the interface
control word bit 7 'Error Acknowledge' when releasing the 'Switch On' Flag.
3.4 Intf Go To Initial Pos Flag Behavior
Setting the Intf Go to Initial Pos Flag Behavior to 'Enter Operation Enabled' sets the interface
Control Word bit 13 'Go To Initial Position' in state 'Ready to Operate' (State: 6), normal
operation of this behavior is to move to the 'Initial position' after enabling.
