$MA_SAFE_STOP_SWITCH_TIME_F
Transition time STOP F to STOP B
Min. input limit: 0.0
Protection level: 7/2
Time after which, for a STOP F with active monitoring functions, a change is made to STOP
B.
The parameterized value must be selected as low as possible.
During this time, e.g., another braking response can be activated using synchronous
actions.
The changeover is also made if a STOP C/D/E occurs during this time.
$MA_SAFE_PULSE_DISABLE_DELAY
Delay time, pulse cancellation
Min. input limit: 0.0
Protection level: 7/2
For a STOP B, the axis is braked with speed setpoint 0 (or OFF3 ramp). After the delay
time defined in this data, the braking mode changes to STOP A for pulse cancellation.
The parameterized value must be selected as low as possible.
The pulses are cancelled earlier than defined in this machine data if the condition for the
pulse cancellation is present via MD36960: $MA_SAFE_STANDSTILL_VELO_TOL or via
MD36620: $MA_SERVO_DISABLE_DELAY_TIME.
If the timer in this machine data is set to zero, then an immediate transition is made from
STOP B to a STOP A (immediate pulse cancellation).
MD36960 $MA_SAFE_STANDSTILL_VELO_TOL
MD36620 $MA_SERVO_DISABLE_DELAY_TIME
MD36060 $MA_STANDSTILL_VELO_TOL
$MA_SAFE_PULSE_DIS_CHECK_TIME
Time to check pulse cancellation
Min. input limit: 0.0
Protection level: 7/2
This machine data specifies the time when, after pulse cancellation has been requested,
the pulses must be actually cancelled.
The time that elapses between deleting the SGA "enable pulses" and detecting the SGE
"pulses cancelled status" may not exceed the time limit set in this data.
Note:
If this time is exceeded, a STOP A is initiated.
