Programming System Variables
The Speed/Direction to Start Homing Axis value is signed. The sign
specifies the direction the axis is to move.
Planning a Home Axis Move
Figure 9.1 shows a typical ladder program block diagram to initiate a
word 5 command from the SLC processor. Other commands are
initiated by setting appropriate values in the data tables and copying
data to appropriate module output words. Examples of these
commands include:
Set Home
Set Retract
Preset Position
Set Offset
Set In-Position Band
Set Excess FE Limit
Set Axis Gain
Set VFF
Figure 9.1 Home Axis Command Block Diagram
If: Then:
The speed specified is
greater than the maximum
axis speed
The speed for the move is limited to the
maximum axis speed.
Any error occurs while
homing the axis
The SLC processor is notified with an
appropriate fault code.
