Enables MDI. This bit must be = 1 if you control the converter using MDI.
Specifies the MDI mode:
0: Positioning: Traverse the axis with position control using the target position.
1: Set up: Traverse the axis position-controlled using velocity input
While operational, the axis operating mode can be switched over from "Set up" to
"Positioning".
If "Set up" is active, then the two bits
Intermediate stop:
0: The converter stops the axis and maintains the axis in position after standstill. The
actual traversing block still remains valid.
1: The axis continues the interrupted traversing block.
Reject traversing block:
0: The converter stops the axis and maintains the axis in position after standstill. The
converter can no longer continue the actual traversing block.
1: Axis waits for a new start command.

and define the direction of travel.
