Parameterization - Siemens SINUMERIK 840D sl Function Manual

Note
From software release 4.7 SP2, the brake test integrated in the drive can also be used in
conjunction with SINUMERIK Safety Integrated. You can find an application example on the
Internet at our "Industry Online Support":

Parameterization

The user can use the following axis-specific NCK machine data to parameterize the function
test of the mechanical braking system:
MD37000 $MA_FIXED_STOP_MODE
MD37030 $MA_FIXED_STOP_THRESH‐
OLD
MD37050
$MA_FIXED_STOP_ALARM_MASK
MD36966 $MA_SAFE_BRAKETEST_TOR‐
QUE
MD36967 $MA_SAFE_BRAKET‐
EST_POS_TOL
MD36968 $MA_SAFE_BRAKETEST_CON‐
TROL
The function test of the mechanical braking system is enabled by setting bit 1 in MD37000
$MA_FIXED_STOP_MODE. If the user needs to travel to a fixed stop with this axis from the
part program, then bit 0 can also be set. It is internally monitored to check that only one type
of travel to fixed stop is active at a time. In the case of an error, Alarm 20092, "Axis % Travel
to fixed stop still active" is issued.
MD37000 $MA_FIXED_STOP_MODE: Travel to fixed stop mode
The function test of the mechanical braking system is enabled by setting bit 1 in MD37000
$MA_FIXED_STOP_MODE. If the user needs to travel to a fixed stop with this axis from the
part program, then bit 0 can also be set. It is internally monitored to check that only one type
of travel to fixed stop is active at a time. In the case of an error, Alarm 20092, "Axis % Travel
to fixed stop still active" is issued.

Enters the test torque
Position tolerance, brake test
Bit 0 = 0: Drive MD1192/p1532 is used as the average
value of the torque limit.
Bit 0 = 1: The measured torque at the instant in time that
the brake test is selected is used as the average value
of the torque limit.
Bit 1 = 0: The torque limit value must be reached during
the programed travel distance.
Bit 1 = 1: The torque limit value must be reached during
the programed time (TV_FXSreached parameterization
FB11).
