13.2.5.3 Positioning modes
According to the traversing range/application, different position modes are available for a
positioning function which are described in the following table.
Note!
For absolute positioning the home position must be known!
If an absolute positioning (positioning modes 1 ... 2 and 11 ... 16) is started
although the home position is not known, an error message is output.
In this case a programming error has occurred and the program flow must be
reset.
If the error only occurs in a sequence profile, the last valid deceleration is used
to decelerate the drive to standstill.
Positioning mode
1 Absolute
The axis travels to an absolute position.
Reference for the absolute position is zero position.
The home position must be known.
The traversing range is limited:
to 214748.3647 [unit]
by the internal display area (±2
31
increments)
Not possible with "modulo" traversing range.
2 Absolute TP
Like mode 1, but with profile change when a touch probe is detected.
Touch probe positioning
. (C 397)
5 Relative
The axis is traversed by a distance.
Reference for the distance is the target position of the profile executed before.
The feed per positioning is limited:
to 214748.3647 [unit]
by the internal display area (±2
31
increments)
6 Relative TP
Like mode 5, but with profile change when a touch probe is detected.
Touch probe positioning
. (C 397)
7 Speed
Continuous constant travel.
Only possible with "unlimited" and "limited" traversing range
This mode does not approach a defined position, but follows the profile.
Acceleration and deceleration are based on profile values.
The traversing direction is defined by the sign of the traversing speed.
Stopped through break signal.
8 Speed TP
Like mode 7, but with profile change when a touch probe is detected.
Touch probe positioning
. (C 397)
11 Absolute CW
The axis travels in CW direction to an absolute position.
Only possible with "modulo" traversing range
Reference for the absolute position is zero position.
In this direction the zero position of the axis can be overtravelled.
12 Absolute CW TP
Like mode 11, but with profile change when a touch probe is detected.
Touch probe positioning
. (C 397)
