Data Description
8.3 Interface signals
SGE deselect ext. STOP C
This SGE requests "braking with n
When this stopping type is initiated, the safe acceleration monitoring (SBR) is acti-
vated. In addition, the timer set in 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:
1 signal:
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 MD 36953/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:
1 signal:
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).
