Present Position Preset Section 6-17
6-17-1 Executing Present Position Preset
To execute present position preset, set the following addresses for the IOWR
instruction’s control code (C) and then transfer the present position preset
value to the MC Unit. For details on the Command Area, refer to
3-6 Com-
mand Area . For details on IOWR specifications, refer to SECTION 4 Data
Transfer and Storage .
Ladder Programming
Example In this example, the X-axis present position is set to 10,000. The MC Unit is
mounted to a CS-series PLC and assigned unit number 0, and the data to be
transferred (i.e., the present position) is stored in words D00100 and D00101.
Both the IOWR operands and the data to be transferred are assumed to be
normal.
When debugging, check the Error Flags from the ladder program.

The minimum setting unit is set to 2 (for 0.01), the dis-
play unit is set to 0 (for mm), and the reference origin
offset is 3.99 [mm] (i.e., 399 x 0.01) if the data is 399.
