Positioning mo
de:
0: Relative (see also bit
⑨).
1: Absolute (the axis must be referenced).
These signals are only effective if, in the
interface for analog signals, the value
⑥
is
not interconnected. See also the table
below.

⑦
Direction selection for "Set up" (Bit
② = 1):
Bit
⑥ = 1: Positive direction.
Bit
⑦ = 1: Negative direction.
If both bits are the same, the axis stops.
⑧
Accept setpoint:
0
→ 1: Start axis
Is only active, if bit
⑨
= 0.
⑨
1: Continuous mode:
The converter continually accepts changes to the p
osition setpoint. In this mode, relative
positioning is not permitted (see bit
⑤).
0: The converter starts using bit ⑧
.
You have now interconnected the digital signals for controlling the direct setpoint input.
