Index.BlendInitiate (Epsilon EP-P only)
This program instruction is used to allow an index to complete its move at the velocity of another index. A blended index
accelerates towards its index velocity using its accel ramp. The index will run at velocity before using its deceleration ramp
to accelerate or decelerate towards the velocity of the next index specified. This differs from the compound index where the
index finishes using the accel ramp of the next index.
The index that is to be "blended into" is on the command line in parenthesis immediately after the Index.BlendInitiate
command.
Index.BlendInitiate into (1)
This command will cause index zero to finish at the velocity of Index 1. The value within the parenthesis can also be a
variable. The following example will operate the same as the previous.
Index.0.BlendInitiate into (var.var0)
The next index that is to be blended must:
•Exist
Have the same time base as the present index (synch verus real time)
If the index does not exist or the time base is different, the blended index will convert into a regular compound index.
The direction of the next index (blended into index) is not looked at. Hence, blending an index into another index will not
cause the index to cross through zero velocity.
