position will be truncated to the maximum or minimum position until the spline re-enters the

A.1.58 Map Output to Axis Position
Character: None
Decimal: 127
Hexadecimal: 0x7F
Command Value: Axis and Position Select (see below)
This command maps the drive output for this axis to an axis’s position. Note that this command is
not valid on pressure axes. This command may be used for applications where a chart recording
analog inputs must be used to capture a position graph. The Command Value is used to select
the axis, the position type (Command, Target, or Actual), and the direction of the drive output.
There are two separate mappings for the direction of the drive output:
In the first (positive) mapping, a position at or below the retract limit gives an output of 0V, a
position at or above the extend limit gives an output of 10V, and positions between the two are
linearly interpolated using the following formula:
In the second (negative) mapping, a position at or below the retract limit gives an output of 10V, a
position at or above the extend limit gives an output of 0V, and positions between the two are
linearly interpolated using the following formula:
Note: The drive outputs are not precision outputs. The output may not be exactly the value you
specify. Look up specifications in the online help index for the tolerance on your particular
interface module’s drive outputs.
