IP 266 Machine Data, Modes and Traversing Programs
Example for Figure 5-20
You start mode 6 with the following parameters:
• Override 100%
• Absolute target coordinate: 30 mm
Table 5-7. Drive Performance in Absolute Increment Mode
Starting point A must be located
in front of defined absolute target
position B
Starting point C must be located
behind defined absolute target
position B
The drive moves forward to the specified
target position at 100% incremental speed.
The drive moves in reverse to the specified
target position at 100% incremental speed.
In the example,
50 mm forward
In the example,
40 mm in re-

Function
The IP 266 responds differently to "Start" when the axis is rotary rather than
linear. It computes the shortest possible path to the target position, and positions
the axis accordingly.
If the distance is the same in both directions, the forward direction (clockwise)
has priority. Backlash is not taken into account. If the axis is already at the target
position, no movement is made, i. e. only the displacement of the object to be
positioned is taken into account, not that of the motor.
The "FORWARD" and "REVERSE" functions can also be invoked in this mode.
