9.6 Interface signals
0 signal: "Pulse cancellation" is requested
1 signal: "Pulse cancellation" is not requested
SGE deselect ext. STOP C
This SGE requests "braking with n
When this stopping type is initiated, the safe monitoring of the acceleration (SBR) is activated.
In addition, the timer set using MD36952/p9552: $MA_SAFE_STOP_SWITCH_TIME_C / "SI
Motion transition time STOP C to SBH" is started.
After this time has elapsed, the system automatically changes over to SBH.
If a stop request is active, SGA "STOP C is active" is set in the same way as it would be for
an internally triggered STOP C.
0 signal: "Braking with n
1 signal: No request for "Braking with n
Note
Stopping with an external STOP A (pulse cancellation) has a higher priority and can interrupt
an external STOP C (braking along the OFF3 down ramp).
SGE deselect ext. STOP D
"Braking along a path" can be requested using this SGE.
When ext. STOP D is triggered, the timer set using MD36953/p9553
$MA_SAFE_STOP_SWITCH_TIME_D / "SI Motion transition time STOP D to SBH" is started.
After this time has elapsed, the system automatically changes over to SBH.
If a stop request is active, SGA "STOP D is active" is set in the same way as it would be for
an internally triggered STOP D.
0 signal: "Braking along a path" is requested
1 signal: No request for "Braking along a path"
Note
Stopping with an external STOP A (pulse cancellation) and/or external STOP C (braking along
the OFF3 down ramp) has a higher priority and can interrupt an external STOP D (braking
along a path).
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: Timer set for "SI Motion transition time STOP
E to SBH" is started.
