Programming

Motion Programs are a series of indexes, homes and jogs that have been previously setup.

You combine these with other programming steps to create a complex motion profile. Each

motion program provides a series of movements in conjunction with other machine functions.

The movements are used to perform a particular machine operation.

Multiple programs can be created using Emerson Motion Control PowerTools® FM-3

software and stored in the FM-3. The FM-3 is capable of storing up to 55 indexes, 99 motion

programs, and a maximum of 1024 program steps in the FM-3 Flash Memory. The amount

of available Flash Memory determines how many programs, program steps, indexes, etc. that

the configuration can hold.

The number of available programs and average number of steps per program are directly

related to each other. The memory is setup such that if you require 99 programs (maximum),

each program can have an average of 10 program steps each. If the number of programs is

reduced to a minimum, you could have as many as 1024 steps in a single program.

Program Instruction Types

Motion Instructions

Index.Initiate

This program instruction is used to initiate a single index. The index is preset to include an

acceleration up to speed, a run at speed and a deceleration to a stop.

A comment is automatically inserted after the index instruction which shows key data about

the particular index. The comment starts with the apostrophe ‘character.

A “Wait For Index.AnyCommandComplete” instruction is also automatically inserted after

each index. This insures that the index has completed before the program continues on to the

next line of code. It is also possible make the program wait until the index is complete and

the following error is less than a specified amount. This is accomplished by changing the

“Wait For Index.AnyCommandComplete” to “Wait For InPosn”. The In Position Window is

configured in the Position view.

Examples:

Index.0.Initiate ‘Incremental,Dist=5.000in,Vel=2.0in/s

Wait For Index.AnyCommandComplete

Index.37.Initiate ‘Absolute,Posn=120.60mm,Vel=50.2mm/s

Wait For InPosn

Index.CompoundInitiate

This program instruction is used to initiate an index which has no deceleration ramp. The

index accelerates or decelerates towards the next index velocity using the next index
