(default) 
$1:  Amp fault disabled; all motors killed on excess following error 
$2:  Low-true amp fault enabled: coordinate system motors killed on fault or excess 
following error

$4  Low-true amp fault enabled; only this motor k8illed on fault or excess following 
error 
$5:  Amp fault disabled; only this motor killed on excess following error 
$6:  Low-true amp fault enabled; only this motor killed on fault or excess following 
error

$8  High-true amp fault enabled; all motors killed on fault or excess following error 
(default) 
$9:  Amp fault disabled; all motors killed on excess following error 
$A:  High-true amp fault enabled; coordinate system motors killed on excess 
following error 
$B:  Amp fault disabled; coordinate system motors killed on excess following error 
$C:  High-true amp fault enabled; only this motor killed on fault or excess following 
error 
$D:  Amp fault disabled; only this motor killed on excess following error 
$E:  High-true amp fault enabled; only this motor killed on fault or excess following 
error 
$F:  Amp fault disabled; only this motor killed on excess following error 
Example 
1.  Motor 1 using flags 1 with amp-enable output, and low-true amp fault disabling all 
motors: I125=$00C000 or I125=$C000 
2.  Motor 1 using flags 1 with direction output, and low-true amp fault disabling all 
motors: 
I125=$01C000 
3.  Motor 1 using flags 1 with amp-enable output, and low-true amp fault disabling only 
coordinate system motors: I125=20C000 
4.  Motor 1 using flags 1 with direction output, and amp-fault disabled, with excess F.E. 
disabling off C.S motors: I125=$31C000 
5.  Motor 1 using flags 5 with amp-enable output, and high-true amp fault disabling only 
this motor: I125=$C0C010
