FM-3 Programming Module Reference Manual
The “Dwell For Time” instruction is in units of seconds with a resolution of milliseconds (0.000
seconds).
If you want to pause the program while an index is executing you should use a “Wait for Time”
instruction described below.
A comment is automatically inserted after the “Dwell For Time” instruction which notes that
the dwell time is in units of seconds. The comment starts with the ‘ character.
Examples:
Do While (TRUE)
Index.0.Initiate ‘Incremetal,Dist=25.000in,Vel=25in/s
Dwell For Time 1.000 ‘Seconds
Loop
Do While (TRUE)
Index.0.Initiate ‘Incremetal,Dist=25.000in,Vel=25in/s
Dwell For Time 1.000 ‘Seconds
Index.1.Initiate ‘Incremental,Dist=15.000in,Vel=25in/s
Dwell For Time 0.500 ‘Seconds
Loop
Dwell for Master Dist
This motion instruction is used to pause program execution for a precise change in distance
on the master encoder signal. This is typically used in synchronized motion applications. This
dwell does not begin until all other motion has completed. When the dwell begins, program
flow will wait until the specified master distance has passed. The units for the dwell value are
specified in the Master Units View.
Example:
Do While (TRUE)
Index.0.Initiate ‘Synch,Incr,Dist=5.0 Inches,Vel=1
Inches/MstrInch
Dwell For MasterDist 12.00 ‘MstrInch
Loop
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
