Axis error flags
The SLC operating system makes no response to out-of-range errors that you may
make when entering parameters in axis-control structures (M0 file). But when the
module detects that you downloaded an out-of-range parameter, it returns a status
code to indicate the word number in the axis- control structure containing the error.
The status code is returned in input image table words 1, 3, 5, and 7, the error flag
words for axes 1, 2, 3, and 4.
Error-flag words return a non-zero status code that points to the invalid entry in the
M0 file. The code is the Control Structure Word + 1. For example, if input image
word 5 (for axis 2) contains the value 130, your entry for KC (proportional gain) in
word 1 of the control structure (M0 word 129) is out of range.
SLC processor’s error codes in the status file
The SLC processor’s operating system responds to a major fault by immediately
halting all processing. The source of the fault is recorded in the SLC processor’s
status file. The fault may be cleared only by cycling power after correcting the fault
condition.
The following error codes are defined for major faults:
0x70 System configuration fault
0x71 Module firmware fault
0x80 Module unspecified hardware fault
0x81 Module flash-memory fault
0x82 Module program-memory fault
0x83 Module data-memory fault
0x84 Module shared-ram fault
0x85 Module watchdog-timeout fault
