Controlling the Displacement with Cycle Angle

Modify the path mate motor definition to control the motor displacement with changes in the cycle angle rather than the time.

  1. Right-click PathMateMotor1 in the MotionManager tree and click Edit Feature .
  2. Under Motion, click Edit.
    The Function Builder appears.
  3. For Independent variable (x), select Cycle Angle.
  4. Optional: Modify the rows of the table as follows:
    Start X End X Value
    0 deg 220 deg 15.0 in
    220 deg 360 deg 35.9 in
    Since 35.9 is the length of the sketched path, the path mate motor specifies the motion for one cycle.
  5. Click OK and click .
  6. Click Calculate (MotionManager toolbar).
    The motion calculation fails and produces an error. The cycle angle calculation is valid only for one cycle of 360 degrees. The length of the motion study is 1 second and motion is calculated at a rate of 10 cycles per second. To address this problem, you can change the cycle rate for the motion study solver to 1 second.
  7. Close the Motion Analysis Messages dialog box.
