FM-3 Programming Module Reference Manual

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).
