Enter the Pr5.31 value of the driver to which you want to communicate from the host to
axis ( * 1 data) of the command block, and transmit the command according to the RS232
communication protocol. For details of communication, refer to P.7-27, "Communication".
Caution • Allow 50ms or longer interval for axis switching when you want to
capture multiple axes data.
• It is recommended for you to repeat the above communication more
than 2 times to confirm the absolute data coincide, in order to avoid
mis-operation due to unexpected noise.
