registration point for registration type indexes.

Index Time Base

Index.#.TimeBase

The time base selects either realtime, which allows
velocities, acceleration and deceleration to be based on
real time, or synchronized, which allows for an external
synchronization signal.

Index Timed Index Enable

Index.#.TimedIndexEnable

This parameter is used in conjunction with the
Index.#.IndexTime parameter. If
Index.#.TimedIndexEnable is active, then the programmed
Velocity, Acceleration, and Deceleration will be used as
maximum values, and the Index Time parameter will
determine how long it takes to perform an index.

Index Velocity

Index.#.Vel

This parameter sets the target velocity of the specific index.
The units for this parameter are specified in the User Units
Setup view. When an index is initiated, it will ramp up to this
velocity at the specified acceleration rate and run at speed
until it decelerates to a stop (assuming the index is not
compounded).

Inertia Ratio

InertiaRatio

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 upon SM-EZMotion module
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 that

commanded motion must be complete and the absolute
value of the following error is less than the InPosnWindow
parameter for the InPosn source to activate.

In Position Window

InPosnWindow

The absolute value of the following error must be less than
this value at the completion of a move for the InPosnTime
before InPosn will activate.

Jog 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.

Jog 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.

Jog 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.

Jog 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.

Jog Stop

Jog.Stop

This is used only in programs to halt jogging motion.
Jogging motion is initiated in programs using the
