Resetting Faults in "Run Anytime" Programs

To reset a fault from a "Run Anytime" program, use Fault.Reset = ON command in the user program. The Fault.Reset command does not clear all types of faults. Some faults require power to be cycled in order to clear the fault. For more information on the method used to clear individual faults, see the Faults section.

After using the Fault.Reset command in a user program, use a Wait For Time 0.100’seconds command to give the drive time to clear the fault and re-enable the drive before initiating motion. If this is not done, the motion will be initiated before the drive is disabled. and the instruction will be ignored.

Example Programs

Out and Return - Simple

Description: Move out to an absolute position and return

Index.2.Initiate‘Absolute,Posn=10.000in,Vel=5.0in/s

Index.1.Initiate‘Absolute,Posn=0.000in,Vel=10.0in/s

Wait For Index.AnyCommandComplete

Out and Return – More Complex

Description: Home, Wait For an input, Move out to an absolute position, set an output, dwell for 1 second, clear the output, return to home position, repeat the out and return sequence until the stop input halts the program.

Home.0.Initiate	‘Sensor,Offset=0.000in,Vel=-10.0in/s
ModuleOutput.1=ON	‘Set the “At Position 1” output
Do While (TRUE)	‘Repeat until the program is halted
Wait For ModuleInput.2=ON	‘Wait for the “Go” Input
ModuleOutput.1=OFF	‘Clear the “At Position 1” output
Index.2.Initiate	‘Absolute,Dist=10.000in,Vel=5.0in/s
Wait For InPosn
ModuleOutput.2=ON	‘Set the “At Position 2” output
Wait For Time 1.000	‘Seconds
ModuleOutput.2=OFF	‘Clear the “At Position 2” output
Index.1.Initiate	‘Absolute,Dist=0.000in,Vel=10.0in/s
Wait For InPosn
ModuleOutput.1=ON	‘Set the “At Position 1” output
Loop
