Fault_Manager
FAULT_MANAGER

Program
This command allows smart handling of faults and alarms. It
acts as an interrupt of 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_MANAGER_RETURN command. Refer to the
Fault_Action page for detailed explanation of each alarm / fault
behavior.

When positive or negative over-travel occurs, XtraDrive 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 label 5. As for other faults, the
XtraDrive acts as defined in the attached table (Fault_Action).
FAULT_MANAGER_RETURN, FAULT_MESSAGE_CLEAR,
ALARM_RESET
Variables: Fault_code, Fault_line
In the current XtraWare software, when alarm/fault occurs, the
user program stops immediately. This forces the user to turn the
power on and off, in order to restart the program and to clear
the fault/alarm. Since this is not a convenient way of working,
when a non-critical fault occurs, a method for handling fault
conditions by user program was added. Yet, there are some
alarm conditions that cannot be overridden.
