Target recognition
The characteristics when the target position are reached (target recognition) depends on the stroke
limitation.
Target recognition
Behaviour after target recognition:
… without stroke limitation
Speed is reached, i.e. the actu
al speed is inside the target
speed window for the duration
of the damping time.
The “Motion Complete” signal is set. The actuator continues to
move at target speed. Monitoring of the speed deviation remains
active. Force remains at the maximum value specified in the speed
record.
… With stroke limitation
–
Stroke limitation is reached
first
The “Stroke limitation” signal is set.
The actuator is braked down to a stop using the parameterised
Quick-Stop deceleration function. Although the target speed has
not yet been reached, the Motion Complete signal was set
(
è
Open-loop operation: the actuator remains at the target position
and is maintained in position with the predefined holding current.
Closed-loop operation: the actuator remains position-controlled.
–
Speed is reached first, i.e.
the actual speed is inside
the target speed window for
the duration of the damping
time.
The “Motion Complete” signal is set. The actuator continues to
move at target speed in closed-loop operation. Monitoring of the
speed deviation remains active; force remains limited to the max
imum stated in the order; stroke limitation remains enabled.
