Bit 2
1 = Positioning to the target position along the shortest path, regardless of bit 0 and 1 values.
0 = Positioning to the target position according to bits 0 and 1.
Bit 3
1 = Before the positioning is started, the position system is reset.
0 = The position system is not reset.
Bit 4
1 = Selected target position is absolute. (Always the same position reference).
0 = Selected target position is relative as defined by bit 6.
Bit 5
1 = Before the positioning is started, the position system is returned to the rollover axis range, ie,
between 0…1 revolutions.
0 = The position system is not returned into the rollover axis range.
Bit 6
Effective only when bit 4 = 0.
1 = Selected target position is relative to the actual position.
0 = Selected target position is relative to the previous target position.
