(Note-1): It is possible to drive the servo input axis except the positioning control (home position return, manual control, speed-torque control,
synchronous control).
Refer to the "Q173D(S)CPU/Q172D(S)CPU Motion controller (SV13/SV22) Programming Manual (REAL MODE)" for details on the
positioning control, home position return, the manual control and the speed-torque control.
(Note-2): Speed change gear can be arranged on two of "Main shaft side", "Auxiliary shaft side" or "After composite auxiliary shaft gear".
"Synchronous control" can be achieved using software instead of controlling
mechanically with gear, shaft, speed change gear or cam etc.
"Synchronous control" synchronizes movement with the input axis (servo input axis,
command generation axis, synchronous encoder axis), by setting "the parameters for
synchronous control" and starting synchronous control on each output axis.
