Setting Up Parameters
(or distance) should be greater than the Registration Window Start position. If a registration
sensor is seen outside of this window (not between the WindowStart and WindowEnd
positions) then it will be ignored.
Example:
Index 0 is defined as a Registration type of index. The user wants the index to run at velocity
for 10 Revs, or until the Torque Feedback reaches 50% continuous torque and then continue
for another 0.5 Revs.
In the Limit Distance parameter, enter 10.0
On the registration tab, select the Analog radio button.
In the analog list box, select Torque Command
In the comparison operator list box, select ">"
In the analog value parameter, enter 50 (Units are established on the User Units view)
In the Registration Offset parameter, enter 1.5
This index would accelerate up to its’ target velocity, and run at speed until one of the
following:
The Limit Distance is approaching, and the index decels down to zero velocity, completing
the move at the Limit Distance. At this point, the Index.#.LimitDistHit source would activate.
Or,
The Torque Command reaches or exceeds 50% continuous, and the index continues at speed
before decelerating to zero velocity at the registration point plus the Registration Offset
distance.
If the Registration Offset distance is in the opposite direction from the move, or is so short
that the motor cannot stop in the specified distance at the programmed deceleration rate, the
motor will decelerate with the programmed ramp, and then back-up to the specified position
(registration point + the Registration Offset).
Index Sources and Destinations
Sources
Index.AnyCommandComplete
Active when any index motion command is completed. If a stop is activated before the index
has completed, this destination will not activate. Deactivated when any new index command
is initiated.
Index.#.Accelerating
This source is active while an index is accelerating to its’ target velocity. Once the index
reaches the target velocity, or begins to decelerate, the Index.#.Accelerating source will
deactivate.
