4-249
1353 $MD_SAFE_STOP_SWITCH_TIME_D 611 digital
Transition time from STOP D to safe operating stop Relevant for:
FD/MSD
Unit:
ms
Default:
100
Minimum value:
0
Maximum value:
60 000
Data type:
float
Becomes effective:
POWER ON
When the time in this timer has expired, a transition is made from STOP D
(initiated by SG or SE) to SBH.
After the time has elapsed, the axis/spindle is monitored for a safe operating
stop. If it has still not reached zero speed, a STOP A or STOP B is initiated.
1354 $MD_SAFE_STOP_SWITCH_TIME_E 611 digital
Transition time from STOP E to safe operating stop Relevant for:
FD/MSD
Unit:
ms
Default:
100
Minimum value:
0
Maximum value:
60 000
Data type:
float
Becomes effective:
POWER ON
When the time in this timer expires, a transition is made from STOP E (initiated
by SG or SE) to SBH.
After the time period has elapsed, the axis/spindle is monitored for a safe
operating stop. If it has still not reached zero speed, a STOP A or STOP B is
initiated.
1355 $MD_SAFE_STOP_SWITCH_TIME_F 611 digital
Transition time from STOP F to STOP B Relevant for:
FD/MSD
Unit:
ms
Default:
100
Minimum value:
0
Maximum value:
60 000
Data type:
float
Becomes effective:
POWER ON
When this time in this timer stage expires, a transition is made from STOP F to
STOP B.
1356 $MD_SAFE_PULSE_DISABLE_DELAY 611digital
Delay time pulse cancellation Relevant for:
FD/MSD
Unit:
ms
Default:
100
Minimum value:
0
Maximum value:
10 000
Data type:
float
Becomes effective:
POWER ON
Delay time to cancel the pulses after STOP B was initiated as a result of safe
standstill monitoring or as a result of a STOP F.
The pulses are cancelled earlier than defined in this data if the condition for
pulse cancellation is present via MD 1360:
$MD_SAFE_STANDSTILL_VELO_TOL.
If the timer stage in this data is set to zero, then an immediate transition is
made from STOP B to STOP A (the pulses are immediately cancelled).
1357 $MD_SAFE_PULSE_DIS_CHECK_TIME 611 digital
Time for checking the pulse cancellation Relevant for:
FD/MSD
Unit:
ms
Default:
100
Minimum value:
0
Maximum value:
10 000
Data type:
float
Becomes effective:
POWER ON
After the time in this timer stage has expired, the pulses must have been
cancelled if this has been requested using the SGE "test stop selection". If the
pulses have not been cancelled after the parameterized time, a STOP A
response is initiated. If the pulses have been cancelled after the parameterized
