Bit 1 Bit 1=1 NC-controlled extended stop and retract enabled.
Bit 1=0 NC-controlled extended stop and retract disabled.
Bit 0 Bit 0=1 When a fault is detected an alarm and Mode Group Stop is triggered and, with
it, stop as well as retract is requested.
Bit 0=0 No alarm or Mode Group Stop is triggered if a fault is detected.

Bit 2
Relevant for 611D only.
Bit 2=1 A retraction movement is triggered if the generator speed of an axis/spindle
falls below the threshold value.
Bit 2=0 A retraction movement is not triggered if the generator speed of an
axis/spindle falls below the threshold value.
Bit 1
Relevant for 611D only.
Bit 1=1 A retraction movement is triggered if the DC link voltage of an axis/spindle falls
below the threshold value.
Bit 1=0 A retraction movement is not triggered if the DC link voltage of an axis/spindle
falls below the threshold value.
Bit 0 Bit 0=1 A retraction movement is triggered if the retraction threshold of an FA is
exceeded.
Bit 0=0 A retraction movement is not triggered if the retraction threshold of an FA is
exceeded.
Active: at once
