Registration Sensor
Index.#.SensorTrigger
If registration to Sensor is selected, when this destination activates, motor position is captured
and is used as the registration point for registration type indexes.
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.
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
FM-3 reset. InitiallyActive can be assigned to any destination that does not create motion (i.e.
indexes, jogs, homes, programs).
