Indexes
An index is a complete motion sequence that moves a specific distance or to a position. This
motion sequence is a combination of a programmed velocity, an acceleration time to
maximum velocity, a deceleration time from maximum velocity, a final travel distance or
position, an optional dwell time at zero speed after the distance or position has been reached,
and an index repeat count.
Figure 83: Indexes Setup Screen
The basic FX drive has thirty-two (32) indexes available. When the Number parameter is
selected, PCX will show the number of available indexes in the lower left corner of the Index
screen (Range). You can initiate an index using the Initiate Index input function.
Index Types
Six types of indexes (Incremental, Absolute, Feed Sensor, Registration, Rotary +, and Rotary
-) can be selected. The number of index parameters shown in the index screen will change
depending on the index type selected. Each index type is explained on the following pages.
Incremental Index
An Incremental Index will move the motor a specified distance in the + or - direction
regardless of starting position. The distance from the starting position is a key factor in
Incremental Indexes.
