If e.g. in case of a profile linkage, several profiles are to be executed with the same
speed, the corresponding profile parameters "speed" can all refer to the same table
position.
For an easier assignment and identification of the entered values, each table position
can be optionally provided with a comment in the »Engineer«.

Positioning modes
Depending on the traversing range/application, you can select between different
positioning modes which are described in the below table.
Note!
For absolute positioning, the home position must be known!
• If an absolute positioning process (positioning modes 1 ... 2 and 11 ... 16) is
started although the home position is not known, an error message is
indicated.
– 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.
The modulo positioning modes may involve reversing processes!
• If a modulo positioning process (positioning modes 11 ... 16) is started at an
initial speed other than zero, the target position may be overtravelled and a
reversing process may follow, depending on the selected deceleration / S-
ramp time parameters. This would also cause e.g. counter-clockwise rotation
in the "Absolute CW (modulo)" positioning mode.
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.
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 on touch probe detection.
