4 Data Descriptions
4.1 Machine data
36964 $MA_SAFE_IPO_STOP_GROUP
MD number Grouping safety IPO response
Default: 0
Change effective after RESET
Data type: BYTE
Meaning This MD influences the channel-wide IPO stop response distribution of Safety Integrated.
It is only effective for Safety Integrated axes/spindles.
0 =
•
with the safety/axis/spindle, then the user is responsible in implementing this using PLC or
synchronous action logic combinations.
36965 $MA_SAFE_PARK_ALARM_SUPPRESS
MD number Suppression of Alarm "Axis not safely referenced" during parking
Default: FALSE
Change becomes effective after POWER ON:
Data type: BOOLEAN
Meaning Enable the suppression of Alarms 27000/300950 "Axis not safely referenced" when the
"Parking" function is selected.
Corresponds with ...
36966 $MA_SAFE_BRAKETEST_TORQUE
MD number Brake test, holding torque
Default: 5%
Change becomes effective after POWER ON:
Data type: DOUBLE
Meaning Specifies the torque or force for the function test of the brake mechanical system. The
holding brake must be capable of applying this torque without any axis slippage.
Activating the appropriate test function via MD $MA_FIXED_STOP_MODE, bit 1. This MD
must be a minimum of 10 % above the actual torque when selecting the brake test (i.e.
with the brake open). This guarantees that if the brake is defective, the motor can again
brake the axis. If this is not the case, the brake test is aborted with Alarm 20095.
If the drive MD 1192 is not correctly parameterized, then the required safety margin is
increased by twice the margin between the real torque and that parameterized in MD
1192.
36967 $MA_SAFE_BRAKETEST_POS_TOL
MD number Position tolerance, brake test
Default: 1
Change becomes effective after POWER ON:
Data type: REAL
Meaning Maximum position tolerance for the function test of the brake mechanical system. If the
axis position deviates from the position by more than this tolerance, when the brake test is
selected, then the function test for the brake mechanical system is aborted.
The corresponding test function is activated via MD $MA_FIXED_STOP_MODE, bit 1.

SINUMERIK 840D/SIMODRIVE 611 digital SINUMERIK Safety Integrated (FBSI) - Edition 11.03
Min. input value: 0
Protection level (R/W) 7/2
Applies from SW 4.4.18
All other axes-spindles in the channel are notified of the
IPO stop response of this axis (default)
1 = For internal STOPs, the axes and machining spindles, interpolating with the
axis involved, are also additionally influenced via the initiated safety alarms. On
the other hand, other axes/spindles in the channel continue to run without
any disturbance.
For external STOPs (without alarm) all of the other axes/spindles remain
unaffected by the safety axis/spindle stop. This allows, for example, the
pulses of the spindle to be safely cancelled (using an external STOP A) so that
this spindle can be manually rotated and the axis can still be safely monitored
when moving.
If, in some machining situations, the other axes/spindles should stop together
