Setting Up Parameters
Index Name
The User can specify an Index name of up to 12 alphanumeric characters. This allows
assigning a descriptive name to each index indicating different machine operations.
IndexType
Select the index type from Incremental, Absolute, Registration, Rotary Plus, or Rotary Minus.
Click the down arrow on the parameter list box to select the desired type of Index profiles, as
follows:
Incremental Indexes run a specified distance from the current position.
Absolute Indexes move to an exact position with respect to the home reference point. The
absolute index could run in either a clockwise (CW) or counterclockwise (CCW) direction
dependent on the current position when it is initiated.
A Registration Index runs at the specified velocity until a registration sensor is seen or until
it reaches the Registration Limit Distance. If a Registration Sensor is seen, then the index runs
an additional Registration Offset distance.
Rotary Plus and Rotary Minus type indexes are typically used in applications which use rotary
rollover. These absolute indexes are forced to run in a specific direction regardless of the
starting point.
Time Base
This list box selects the Time Base for the index velocity and acceleration/deceleration. Real-
time and Synchronized are the allowed selections.
Distance/Position
The Distance/Position parameter is a signed value which specifies the distance the index will
travel (incremental index) or the absolute position the index will move to (absolute index). In
the case of an incremental index, this parameter also determines the direction the index will
travel. If an index type of Registration is selected, then this is a limit distance, or the
maximum distance the index will travel if a registration sensor is not seen.
Velocity
This sets the target velocity for the index profile. The velocity parameter is unsigned and must
be greater than zero. Direction of the index is not determined by the velocity, but by the
Distance/Position parameter.
Acceleration
Average Acceleration rate used during the index. Units are specified on the User Units View.
Deceleration
The Deceleration parameter specifies the deceleration value to be used during the index in
user units.
