This parameter is provided to allow the user to select several predefined digital input routing macros to control the sequencer. When a value between
0 and 3 is selected the drive processor continuously updates the destination parameters for T25 digital I/O 2, T26 digital I/O 3 and T27 digital input 4
and the "enable sequencer latching bit" (Pr 6.40). When a value of 4 is selected the destination parameters for these digital I/O and Pr 6.40 can be
modified by the user. (Note any changes made to the destination parameters only become active after a drive reset.)

When this bit is set the drive remains active even when the run command has been removed and the motor has reached standstill. The drive goes to
the 'StoP' state instead of the 'rdy' state.
