Inertia Ratio
Inertia
This specifies the load to motor inertia ratio. For example, a value of 25.0 specifies that the load inertia is 25 times the inertia
of the motor.
Initially Active
InitiallyActive
This source, when assigned to a destination, will activate the destination on power-up or a reset. InitiallyActive can be
assigned to any destination that does not create motion (i.e. indexes, jogs, homes, programs).
In Position
InPosn
This source activates when commanded velocity is zero and the absolute value of the following error is less than the
InPosnWindow for at least the amount of time specified in the InPosnTime parameter.
In Position Time
InPosnTime
This parameter is the minimum amount of time, in seconds, that commanded motion must complete and the absolute value of
the following error is less than the InPosnWindow parameter for the InPosn source to activate. If set to zero (default), then
InPosn will activate as soon as motion stops and the following error is less than the In Position Window parameter.
In Position Window
InPosnWindow
The absolute value of the following error must be less that this value at the completion of a move for the InPosnTime before
InPosn will activate.
Any Command Complete
Jog.AnyCommandComplete
The Jog.AnyCommandComplete bit will activate when either Jog 0 or Jog 1 completes its deceleration ramp and reaches zero
commanded speed. It deactivates when another jog is initiated.
Minus Activate
Jog.MinusActivate
This destination is used to initiate jogging motion in the negative direction using the jog parameters of the jog selected by the
Jog select input function. Jogging will continue as long as the destination is active. The motor will decelerate to a stop when
the destination is deactivated. This is level sensitive.
Plus Activate
Jog.PlusActivate
This destination is used to initiate jogging motion in the positive direction using the jog parameters of the jog selected by the
Jog select input function. Jogging will continue as long as the destination is active. The motor will decelerate to a stop when
the destination is deactivated. This is level sensitive.
Select
Jog.Select0
This destination is used to select between the jogs. It is used along with the Jog.PlusActivate and Jog.MinusActivate
destinations. If the Jog.Select0 destination is not active then the Jog.0 setup parameters will be used for jogging. If the
Jog.Select0 input function is active, the Jog.1 setup parameters will be used for jogging. If the Jog.Select destination is
changed during jogging motion the axis will ramp smoothly from the previously selected jog velocity to the new jog velocity
using the specified jog acceleration. This is level sensitive.
Stop
Jog.Stop
This is used only in programs to halt jogging motion. Jogging motion is initiated in programs using the Jog.#.MinusActivate or
Jog.#.PlusActivate instructions, and using the Jog.Stop will cause the motor to decelerate to a stop at the Jog.#.Decel rate for
the jog that is active.
