X-SEL main unit
The pulse train command of the extension motion control board control axis shall be output to the main
CPU control axis. With this setting, the actuator operates (positioning and synchronization
(synchronization of electronic cam, etc.)) following the extension motion control board output pulses as a
slave. This eliminates the wiring of extension motion control board and PIO board (except for connection
with external devices).

Caution
The number of main CPU control axes which can be specified as a slave to the extension motion control
board using the XSEL-R/S controller, is up to seven per board (All eight axes cannot be specified as
slaves). When all eight axes are specified, the error No. 527: Extension motion control board pulse
output setting parameter error will occur. In order to operate all eight axes as slaves, two extension
motion control boards are required.
