9-16 Programming System Variables
1 s = Slot number for the SLC Servo Module
Floating-Point Values
Three floating-point value data items are shown below. We
recommend that you incorporate the following rung in the ladder
program to convert the integer data from the module to floating-point
data for comparison or display purposes.

Actual Position I:s.6-I:s.7 Float –axis travel limit to
+axis travel limit 0.0 The current actual position of the
axis; if inhibited, returns 0.
Following Error I:s.8-I:s.9 Float –axis travel limit to
+axis travel limit 0.0 The current following error of the
axis; if inhibited, returns 0.
Current Speed I:s.10-I:s.11 Float -physical limit to +physical
limit 0.0 The current speed of the axis; if
inhibited, returns 0.
