Home Marker Distance
These parameters are read only. They correspond to the current home marker
distance. These parameters will contain the distance to marker calculated
when the axis stopped after the home switch went false during the last
homing operation.
5731 Axis 1 home marker distance 5737 Axis 7 home marker distance
5732 Axis 2 home marker distance 5738 Axis 8 home marker distance
5733 Axis 3 home marker distance 5739 Axis 9 home marker distance
5734 Axis 4 home marker distance 5740 Axis 10 home marker distance
5735 Axis 5 home marker distance 5741 Axis 11 home marker distance
5736 Axis 6 home marker distance 5742 Axis 12 home marker distance
#5751 to 5763
Home Marker Tolerance
These parameters are read only. They correspond to the current home marker
tolerance. These parameters will contain the tolerance value at power turn on
and will represent 3/8 of an electrical cycle of the feedback device converted
to current axis programming units (inch/metric, degrees or revolutions).
5751 Axis 1 home marker tolerance 5757 Axis 7 home marker tolerance
5752 Axis 2 home marker tolerance 5758 Axis 8 home marker tolerance
5753 Axis 3 home marker tolerance 5759 Axis 9 home marker tolerance
5754 Axis 4 home marker tolerance 5760 Axis 10 home marker tolerance
5755 Axis 5 home marker tolerance 5761 Axis 11 home marker tolerance
5756 Axis 6 home marker tolerance 5762 Axis 12 home marker tolerance
Paramacro parameters are provided by on the control to allow a means of
communicating values between the PAL program and the part program.
This is done by assigning values to specific paramacro parameters or PAL
flags. They are:
Input parameters: Use these parameters to transfer data from PAL to the
part program.
Output parameters: Use these parameters to transfer data from the part
program to PAL. Some applications may, however, use the output flags
to transfer data from PAL to the part program as needed.
