8.8.2.3 Positioning modes
For positioning, it is possible to select from different positioning modes in relation to the type of
axis/application. These modes are described in the following table.

Stop!
In the positioning modes "continuous" and "relative", the "TroubleQuickStop" error
response occurs in the Lenze setting when the maximum travel distance is exceeded
( C01213/1 ).  Monitoring of the maximum travel distance ( 480)

Note!
For absolute positioning, the home (reference) position must be known!
• If absolute positioning (positioning modes 1, 4, 5, 8, 11, 12) is started although the
home position is not known:
• The error message set in C00595/8 is displayed (Lenze setting: "WarningLocked").
• The error message " Ck08: Home position unknown " is entered into the logbook.
Positioning mode Info
1 Absolute (shortest path) Travelling along the axis takes place until an absolute position is
reached via the shortest path.
• Reference for the absolute position is the zero position.
8 Absolute (shortest path) to TP
(from version 06.00.00)
2 Continuous In these two modes, no particular position is approached but
travelling takes place at the traversing speed stipulated by means of
the profile.
• The values of the profile are used for accelerating and
decelerating.
• The direction of travel is determined by the sign of the traversing
speed.
9 Continuous to TP
(from version 06.00.00)
3 Relative The axis is traversed by a distance.
• Reference for the distance is the target position of the previously
executed profile.
10 Relative to TP
(from version 06.00.00)
Positioning modes for Modulo measuring system (rotary table application)
 Activation of the modulo measuring system ( 470)
4 absolute (Cw)
(from version 06.00.00)
Clockwise travelling along the axis takes place until an absolute
position is reached.
• Reference for the absolute position is the zero position.
• The zero position of the axis can be exceeded in this direction.
11 Absolute (Cw) on TP
(from version 06.00.00)
5 absolute (Ccw)
(from version 06.00.00)
Counter-clockwise travelling along the axis takes place until an
absolute position is reached.
• Reference for the absolute position is the zero position.
• The zero position of the axis can be exceeded in this direction.
12 Absolute (Ccw) on TP
(from version 06.00.00)
