FM-3 Programming Module Reference Manual
Jog.0.PlusInitiate ‘Vel=20in/s
Wait For ModuleInput.2=OFF ‘Stop when the input goes OFF
Jog.Stop ‘Decelerate to a stop
Endif
If (ModuleInput.3=ON) Then ‘Jog- when ModuleInput.3=ON
Jog.0.MinusInitiate ‘Vel=20in/s
Wait For ModuleInput.3=OFF ‘Stop when the input goes OFF
Jog.Stop ‘Decelerate to a stop
Endif
Else
This program flow instruction is used in conjunction with the If/Then/Endif instruction. If the
If/Then test condition evaluates to true the code after the If/Then and before the Else is executed.
If the test evaluates to false the code between the Else and the Endif is executed.
Examples:
If DriveInput.1=ON Then ‘The following two lines are executed if
‘DriveInput.1=ON
DriveOutput.1=ON
DriveOutput.2=OFF
Else ‘The following two lines are executed if
‘DriveInput.1=OFF
DriveOutput.1=OFF
DriveOutput.2=ON
Endif
If (ModuleInput.5=ON) Then ‘Set fast velocity if ModuleInput.5 = ON
Jog.0.Vel = 1.0 ‘in/s
Else ‘Set slow velocity if ModuleInput.5 = OFF
Jog.0.Vel = 0.1 ‘in/s
Endif
For Count/Next
This instruction is used to execute section of code a specific number of times.
Examples:
For Count = 1 to 5
Index.1.Initiate ‘Incremetal,Dist=5.250in,Vel=10.0in/s
Dwell For Time 1.000 ‘seconds
Next
For Count = 1 To 10
Wait For ModuleInput.1 = ON
Index.0.Initiate ‘Incremetal,Dist=5.000in,Vel=50in/s
Wait For Index.AnyCommandComplete
ModuleOutput.1=ON ‘Turn ModuleOutput.1 On
Wait For Time 1.000 ‘seconds
