Use of Auto Read/Auto Write Command
Generally, the read or write command is used while the DC is not moving. The auto command, in contrast, is used
while the DC is moving.
Read/Write Commands
•
The communication distance width is wider than when the DC is moving, so that communications can be accu-
rately performed.

If the DC moving speed is low and positioning is accurate, the communication is not limited by distance (within
reason).
