Position Information (words 4, 5; 8, 9; 12, 13; and 14, 15)
The position words give the present position measured at the transducer. The
position information is in either BCD or binary format. You choose the format
you want through the parameter block. Binary format is compatible with integer
data (16-bit 2’s complement) used by PLC-5 family programmable controllers.
See Appendix H for an explanation of numbering formats.
The maximum position displayed is ±799.900 inches or ±7999.00 millimeters.
If the status words 4, 5 and 8, 9 are specified in the command block to display
position, when the axis exceeds the maximum, the maximum is displayed and
the position valid bit in the second status word turns off.
