$MA_SAFE_STOP_SWITCH_TIME_E
This data defines the time period between the initiation of a STOP E and the activation of a
Safe Operating Stop.
The parameterized value must be selected as low as possible.
After the time has expired, the drive is monitored for a Safe Operating Stop. If the axis/spindle
was still not able to be stopped, then STOP B is initiated.
$MA_SAFE_STOP_SWITCH_TIME_F
Transition time STOP F to STOP B
Min. input limit: 0.0
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
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 para‐
meterized 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).
