2.2 List of parameters
Description: Sets the signal source to accept the values for edge-triggered selection (BI: p2649 = 0 signal) in the operating mode 
"direct setpoint input/MDI".
BI: p2650 = 0/1 signal and BI: p2649 = 0 signal
Values are accepted, edge-triggered (refer to parameter under dependency).
Dependency: Refer to: p2640, p2641, p2642, p2643, p2644, p2645, p2648, p2649, p2651, p2652, r2684
Notice: The parameter may be protected as a result of p0922 or p2079 and cannot be changed.
Note: The status signal r2684.12 = 0/1 signal is used for acknowledgment.
The operating mode "direct setpoint input/MDI" can be influenced via the following signals:
- intermediate stop via BI: p2640.
- reject traversing task via BI: p2641.
Description: Sets the signal source for the positive direction selection in the operating mode "direct setpoint input/MDI".
Dependency: Refer to: p2576, p2648, p2649, p2650, p2652, p2653, p2654
Note: The following applies for "setting-up":
- the traversing direction can be entered using this binector input.
- if both directions (p2651, p2652) are selected, then the axis remains stationary (zero speed).
- if both directions (p2651, p2652) are de-selected, then the axis remains stationary (zero speed).
The following applies for "positioning":
Using binector inputs p2651 and p2652, when the modulo correction (BI: p2577 = 1 signal) is activated and for 
absolute positioning (BI: p2648 = 1 signal), the traversing direction is specified as follows:
BI: p2651 / BI: p2652
0 signal / 0 signal: Absolute positioning through the shortest distance.
1 signal / 0 signal: Absolute positioning in the positive direction.
0 signal / 1 signal: Absolute positioning in the negative direction.
1 signal / 1 signal: Absolute positioning through the shortest distance.
Description: Sets the signal source for the negative direction selection in the operating mode "direct setpoint input/MDI".
Dependency: Refer to: p2576, p2648, p2649, p2650, p2651, p2653, p2654
Note: The following applies for "setting-up":
- the traversing direction can be entered using this binector input.
- if both directions (p2651, p2652) are selected, then the axis remains stationary (zero speed).
- if both directions (p2651, p2652) are de-selected, then the axis remains stationary (zero speed).
