SGE deselect ext. STOP E

This SGE can be used to request a stop via the function "extended stopping and

retraction" (ESR). When an external STOP E is initiated the timer set using

MD36954: $MA_SAFE_STOP_SWITCH_TIME_E / p9554: "SI Motion transition

time STOP E to SBH" is started.

After this time has elapsed, the system automatically changes over to SBH.

If a stop request is active, SGA "STOP E is active" is set in the same way as it

would be for an internally triggered STOP E.

Stopping with an ext. STOP A (pulse cancellation), ext. STOP C (braking along

the OFF3 down ramp) and ext. STOP D (braking along a path) have a higher

priority and can interrupt an ext. STOP E.

STOP E only produces a different response than STOP D if the user has con-

figured the ESR function -- extended stop and retract -- and initiation of the ESR is

programmed depending on $VA_STOPSI or $A_STOPESI. If no ESR is active, the

STOP E behaves like a STOP D. However, if the ESR was incorrectly configured,

there is a delay up to the time $MC_ESR_DELAY_TIME1 and $MC_ESR_DE-

LAY_TIME2 compared to STOP D until the braking operation is initiated.

After these times have expired, braking is initiated at the current limit.

Close SGE brake (only the drive)

Using this SGE, a mechanical brake, that is controlled from the drive brake control,

is closed. It is used to check brake closing while testing the mechanical brake

S If this SGE is set, the brake is closed.

S If this SGE is deleted, then the brake assumes the status of the drive brake

control -- i.e. it is not forcibly opened (no positive opening).

This SGE must be connected to the brake control using a BiCo interconnection in

the drive (p0858 to source r9719, bit 13). This connection is parameterized as
