36954 $MA_SAFE_STOP_SWITCH_TIME_E
MD number Transition time STOP E to safe standstill
Default: 0.1
Change becomes effective after POWER ON:
Data type: DOUBLE
Meaning Time after which a changeover is made from Stop E to a safe operating stop.
Special cases, errors
Corresponds with ...
36955 $MA_SAFE_STOP_SWITCH_TIME_F
MD number Delay time STOP F to STOP B
Default: 0
Change becomes effective after POWER ON:
Data type:
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 $MA_SAFE_PULSE_DISABLE_DELAY
MD number Delay time pulse cancellation
Default: 0.1
Change becomes effective after POWER ON:
Data type: DOUBLE
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 $MA_SAFE_PULSE_DIS_CHECK_TIME
MD number Time for testing pulse cancellation
Default: 0.1
Change becomes effective after POWER ON:
Data type: DOUBLE
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.
