Event-based Motion View

To display the event-based view:

From a motion study, select Motion Analysis from the Motion Study Type list (MotionManager toolbar). Click Event-based Motion View (right end of the MotionManager toolbar).

Tasks

Event-based motion requires a set of tasks. The tasks can be sequential or can overlap in time. Each task is defined by a triggering event and its associated task action. Task actions control or define motion during the task.

The result of an event-based motion task is an action.

Name Displays the task names. Click a cell to modify the name.
Description Displays the task descriptions. Click a cell to modify the description.

Triggers

A task trigger is the event that drives the motion control action for a task. You can define task triggers based on time, previous tasks, or sensed values, such as component position.

Trigger
You can create triggers from:
  • Sensors:

    Interference detection

    Detects collisions.

    Proximity

    Detects motion of a body crossing a line.

    Dimension

    Detects the relative position of components from dimensions.
  • Previous tasks in the event schedule
  • Start and finish times for task actions

Double-click a cell to modify the trigger.
Specifies the triggering task.
Specifies the triggering sensor.
You can include sensors to trigger actions only when you set the Alert condition in the Sensor PropertyManager.
Specifies a time-based trigger.
Condition  
  • Alert On. Triggers the action when the sensor is triggered.
  • Alert Off. Triggers the action when the sensor is off.
  • Task Start. Triggers the action at the start of a triggering task.
  • Task End. Triggers the action at the end of a triggering task.
Time/Delay  
  • For triggering tasks or sensors, displays the time delay for starting the task action. Click a cell to modify the delay.
  • For time-based triggers, displays the start time of the task action. Click a cell to modify the time.

Actions

A task action defines or constrains the motion of one or more components in the assembly. You can define actions to suppress or activate mates, stop motion, or to change values for motors, forces, or torques.

You can define a task action to:
  • Start, stop, or change the value of a constant speed motor, constant force, constant torque, or a servo motor.
  • Stop the motion.
  • Suppress a selected mate.
Feature Indicates a linear motor action.
Indicates a rotary motor action.
(number) Indicates multiple motor actions.
(number) Indicates an action by a mixed selection of features.
Indicates a force action.
Indicates a torque action.
Indicates a suppressed or included mate action.
Indicates a stop motion.
 

Double-click a cell to select one or more features. Select only the features that you can apply the same action.
Action  
  • On. Turns on motors, forces, or torques, and includes selected mates for duration of action.
  • Off. Turns off motors, forces, or torques, and excludes selected mates for duration of action.
  • Change. Changes the value of constant speed motors, servo motors, or constant forces or torques.
  • Stop. Stops the constant speed or servo motors.
Click a cell to change the action.
Value   Specifies the changed constant for changed constant speed motors, or constant forces or torques.
Duration   Specifies the action duration for changed constant speed motors, or constant forces or torques.
Profile   Specifies the shape of constant speed motor profile, or the constant force or torque profile. The profile is calculated from the value and duration.
Click a cell to change the profile.
