Example Operation In this example, the X-axis is moved to X100, so the X target position (the com-
mand’s current position) is 100. Actually, a servo is used and a varying deviation
from 100 develops. The actual current position from the encoder reflects this
deviation.

6-5-11 Word n+1 Bit 11: Transmission Control Bit (All Tasks)
This bit is used to write data to the MC Unit.
The completion of data writing to the MC Unit can be confirmed with the Trans-
mission Completed Flag.
This bit must be on hold until the Transmission Completed Flag is turned ON.
This bit is available when the expansion data area is valid.
Data cannot be written to the MC Unit, read from the MC Unit, and written to the
flash memory at the same time. If they are instructed together, the instructions
are executed in the following order.
Priority: Data written to the MC Unit, data read from the MC Unit, and data written
to the flash memory.
