Quick Start

Home Setup

The example application calls for setup of the following parameters:

Home Reference –The example calls for a Home to Sensor; therefore, “Sensor” is selected as the home reference. Because of this selection, the home profile will travel at its target velocity until the Home.0.SensorTrigger is activated. Figure 88, shows the Home.0.Sensor Trigger has been assigned to ModuleInput.2.

Velocity – The home move travels at this velocity, until the home reference is seen and then stops. If the motor overshoots the sensor, a reverse move is initiated. Other functions may cause additional motion. The example application uses a Home Velocity of 20 inches/min.

Acceleration – Is the average acceleration rate used to accelerate to the target velocity. The example uses an acceleration rate of 100 inches/min/sec.

Index Setup

The example application calls for two Absolute Indexes, and one Incremental Index. Select one of the indexes from the hierarchy window. Figure 91 shows Index0.

Absolute Index

Figure 91: Index Setup View (Absolute Type)

Indexes 0 and 1 are both Absolute type indexes and use the following parameters:

Index Name - Is a 12-character string that gives a descriptive name to an index.

Index Type – Select the desired type of index from the list box. Index0 has been defined as an Absolute type of index. This means the load will travel to an exact position with respect to the home reference point. This index will cause motion in either a positive or negative direction depending on current position of the load with respect to the home reference point.

Position – Is a signed value that specifies the absolute position for the load at the completion of the index. For absolute indexes, direction of travel is determined by the starting position of the index. Index 0 has a Position of 10 Inches, and Index 1 has a Position of 0 Inches.

Velocity – Is the target velocity of the index profile. The velocity parameter is unsigned and is always greater than zero. Direction of the index is not determined by the velocity, but by the Distance/Position parameter. Velocity of the indexes in the example are 100 inches/min.

Acceleration – Is the average acceleration rate used when accelerating to the target index velocity.

Deceleration - Is the average deceleration rate used when decelerating to zero speed, or to the new target velocity.

Incremental Index

The following parameters were setup for Index2:

Index Name - Is a 12-character string that gives a descriptive name to an index.
