* Breakpoints cause a digital output to change state when a specified position is reached
by an encoder. Breakpoints are not supported by the NI SoftMotion Controller when it is
used with an Ormec or CANopen device.
** A high-speed capture records the position of an encoder when a digital line is used as
a trigger. High-speed captures are not supported by NI SoftMotion Controller for
CANopen. You can use two high-speed captures per axis when you are using the
NI SoftMotion Controller with an Ormec device.
