Section
Writing Data with the WRITE DATA Bit
100
3. When transferring data using WRITE DATA, the data must be transferred in
data units. Data transfer should not start or end part-way through the data.
For example, with X-axis sequence #0, the data unit becomes three words
consisting of addresses from 1000 to 1002. If transfer is started or ended
part-way through, a write transfer words error or write destination address
error (error code 8312) will be generated.
4. Any word in the DM or EM area, except for DM 1000 to DM 1999, can be
specified in I+1 (transfer source word) of the Information for Writing Data
settings. If a word in the range DM 1000 to DM 1999 is specified, a write
transfer source word error (error code 8311) will be generated.
5-2-1 Outline
The following example of positioning sequences summarizes how to write data
to the Position Control Unit.
When the WRITE DATA bit (word n+1, bit 12) in the operating memory area is
turned ON, the data in the PC’s DM or EM area designated in the operating data
area, along with the number of transfer words, the transfer source word, and the
transfer destination address, are written to consecutive addresses at the Posi-
tion Control Unit.

The “n” in the operation memory area is the beginning word address in the IR
area, and is determined when the unit number is specified.
The “m” in the common parameters is the beginning word address in the DM
area, and is determined when the unit number is specified.
The “I” in the operation data area is the beginning word address in the data trans-
fer area specified by the common parameters.
