9
Set reference
position
(from SW 1.2)
1 Before SW 1.4 the following applies:
The actual position is set the same as the signaled position at
the end of the block. In conjunction with this, the end of block
means the following:
For a precise stop:
After entering into the precise stop window
For approximate positioning:
After entering into the precise stop window of the next block
After withdrawing the start conditions and external block
change:
Immediately after entering into the precise stop window
From SW 1.4, the following applies:
At the end of the block, the position of the last zero mark is set
the same as the signal position and the drive is referenced.
no
0 –
Note:
Bit 9 = 0 if
Bit 10 = 1 (flying actual value setting) or
Bit 11 = 1 (flying measurement) or
Bit 14 = 1 (Reference to the occurring zero mark)
(from SW 2.1)
1 Active
10

Note:
Bit 10 = 0 if
Bit 9 = 1 (set reference position) or
Bit 11 = 1 (flying measurement) or
Bit 14 = 1 (Reference to the occurring zero mark)

Note:
Bit 11 = 0 if
Bit 9 = 1 (set reference position) or

Bit 14 = 1 (Reference to the occurring zero mark)

12
Traverse along
the shortest
path
(from SW 1.4)
Note:
For axes with modulo correction and absolute position data,
when the bits are set, the shortest traversing distance is calcu-
lated and traversed.
Programming the traversing direction using the velocity sign is
ineffective when the function is active (refer to Chapter 5.5.3).
yes
