9Starting and Stopping Motion
9.1Starting Motion
All of the motion types described in “How Motion Works” on page 23 can be initiated using multiple methods. The two different methods are from assignments, and from user programs. The following section details how each of the different motions are initiated from both assignments and from user programs.
9.1.1 From Assignments
In order to initiate motion from an assignment, a Source must be assigned to one of the Destinations listed below on the Assignments view in PowerTools Pro. Some Destinations are level sensitive while others are edge sensitive. Each of the Destinations associated with starting
Jog.1.Velocity
Jog.1.Accel
Jog.0.Velocity
Jog.0.Accel
Jog.Select
Jog.PlusActivate
motion are listed below.
9.1.1.1 Jog.PlusActivate
Jog.PlusActivate will, when active, cause the motor to run at a specified Jog Velocity in the positive direction. Jog.PlusActivate is a level sensitive assignment meaning that as long as the Destination is active, the Jog will be active. The status of the Jog.Select destination determines which jog profile is used when Jog.PlusActivate activates. If Jog.Select is off (or inactive) then the Jog 0 profile will be used. If Jog.Select is active, then the Jog 1 profile is used.
To stop the jogging motion, simply deactivate the Jog.PlusActivate Destination. The motor will then decelerate using the selected Jog Deceleration ramp.
If Jog.Select activates or deactivates while Jogging is active, the motor will change to the new Jog Velocity using the new Jog Acceleration ramp. Jog Deceleration is only used when Jogging motion is stopped. Figure 110 shows an example of changing Jog.Select while Jog is active.

9.1.1.2 Jog.MinusActivate
Jog.MinusActivate will, when active, cause the motor to run at a specified Jog Velocity in the negative direction. Jog.MinusActivate is a level sensitive assignment meaning that as long as the Destination is active, the Jog will be active. The status of the Jog.Select destination determines which jog profile is used when Jog.MinusActivate activates. If Jog.Select is off (or inactive) then the Jog 0 profile will be used. If Jog.Select is active, then the Jog 1 profile is used.
To stop the jogging motion, simply deactivate the Jog.MinusActivate Destination. The motor will then decelerate using the selected Jog Deceleration ramp.
If Jog.Select activates or deactivates while Jogging is
active, the motor will change to the new Jog Velocity using the new Jog Acceleration ramp. Jog Deceleration is only used when Jogging motion is stopped. Figure 110 above shows an example of changing Jog.Select while Jog is active.
9.1.1.3 Jog.Select
Jog.Select is used solely to determine which Jog Profile is selected when the Jog.PlusActivate or Jog.MinusActivate are activated. To select Jog 0, Jog.Select should be inactive. To select Jog 1, Jog.Select should be active.
9.1.1.4 Home.#.Initiate
The Home.#.Initiate Destination is used to start the home sequence as defined on the Home view. Home.#.Initiate is
