Monitoring of the actuator behaviour
The actuator characteristics can be monitored and controlled by messages and comparators. Further
more, the motor controller has internal protection functions, e.g. to protect internal components from
damage in the event of operator error.

“Motion Complete” message
“Motion Complete” signals the end of an order. A window is defined for each order type (position,
velocity or force mode). As soon as the actual value of the target parameter is in the time window for
the duration of the parameterised damping time, the Motion Complete message (order ended) is
triggered.
