36954
MD number
$MA_SAFE_STOP_SWITCH_TIME_E
Transition time STOP E to safe standstill
840D
Default: 0.1
Min. input value: 0
Max. input value: 60
Change becomes effective after POWER ON:
Protection level (R/W) 7/2
Unit:
Data type: DOUBLE
Applies from SW 6.4.15
Meaning
Time after which a changeover is made from Stop E to a safe operating stop.
Special cases, errors
Corresponds with …
36955
MD number
$MA_SAFE_STOP_SWITCH_TIME_F
Delay time STOP F to STOP B
840D
Default: 0
Min. input value: 0
Max. input value: 60
Change becomes effective after POWER ON:
Protection level (R/W) 7/2
Unit: s
Data type:
Applies from SW 6.4.09
Meaning
Time after which, for a STOP F with active monitoring functions, a change is made to
STOP B. The changeover is also made if a STOP C/D/E occurs during this time,
Special cases, errors
Corresponds with …
36956
MD number
$MA_SAFE_PULSE_DISABLE_DELAY
Delay time pulse cancellation
840D
Default: 0.1
Min. input value: 0
Max. input value: 10
Change becomes effective after POWER ON:
Protection level (R/W) 7/2
Unit: s
Data type: DOUBLE
Applies from SW 3.4
Meaning
For a STOP B, the axis is braked along the current limit with speed setpoint 0. After the
delay time defined in this data, the braking mode changes to STOP A for pulse
cancellation.
Special cases, errors
The pulses are cancelled earlier than defined in this data if the condition for the pulse
cancellation is present as specified in MD 36960: $MA_SAFE_STANDSTILL_VELO_TOL
or MD 36620: $MA_SERVO_DISABLE_DELAY_TIME
If the timer in this data is set to zero, an immediate change is made from a STOP B to a
STOP A (immediate pulse cancellation).
Corresponds with …
MD 36960: $MA_SAFE_STANDSTILL_VELO_TOL
MD 36620: $MA_SERVO_DISABLE_DELAY_TIME
MD 36060: $MA_STANDSTILL_VELO_TOL
36957
MD number
$MA_SAFE_PULSE_DIS_CHECK_TIME
Time for testing pulse cancellation
840D
Default: 0.1
Min. input value: 0
Max. input value: 10
Change becomes effective after POWER ON:
Protection level (R/W) 7/2
Unit: s
Data type: DOUBLE
Applies from SW 3.4
Meaning
This specifies that time where after pulse cancellation has been requested the pulses
must actually be cancelled.
The time that elapses between setting the SGA "enable pulses" and detecting the SGE
"pulses cancelled status" must not exceed the time limit set in this data.
Special cases, errors
If the pulses are not cancelled within this time, a STOP A response is activated.
