ESCRIPTION
This command allows smart handling of faults and alarms. 
It acts as an interrupt in the highest priority when an 
alarm or a fault condition occurs. The user can define the 
actions within the fault manager routine for certain 
conditions. The routine ends with a FAULT_RETURN 
command. Refer to the 
Fault Action
page for detailed
explanation of each alarm /fault behavior.

XPLANATION
When positive or negative over travel occurs, FSP stops
the motor automatically and the user program jumps to 
the FAULT_MANAGER, followed by a jump to label 22, 
executing the HOME command and clears the fault 
message buffer. Afterwards, it starts the program from 
label 5. As for other faults, the FSP acts as defined in the 
attached table 
(Fault Action)
