Absolute Index

Figure 116: 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.

Index Type – Select the desired type of index from the list box. Index2 has been defined as an Incremental type of index.

This means that the load travels an exact distance from the start of the index.
