Example: Definition of units as degrees (°), setup of reference system (
Feed Con-
stant
1115),
Feed Constant = 3600 for resolution of 0.1°; revolution distance = 3600 u
Note: In order to limit the travel range of a rotary table, it can be configured
as a linear axis. Linear movements can be effected via a round axis,
e.g. in the case of a belt conveyor.
Examples for settings of parameter
Operation Mode 1240:
Example: Operation Mode "1 - On", for absolute and relative positioning
Current position Target position Direction of rotation
Example 1 45° 315° clockwise (positive);
target position > act. position
Example 2 315° 45° anticlockwise (negative);
target position < act. position

Direction of rotation depends on values for target position in motion blocks.
Angle 0° is not passed.
Example: Operation Mode "2 – On /Optimized (shortest way)" compared
to Operation Mode "3 – On /Clockwise Rotation" (not optimized)
