SINUMERIK 840D sl/SINAMICS S120 SINUMERIK Safety Integrated (FBSI sl) – 05.2008 Edition
Check the parameterization for the brake test function: The torque for
weight equalization in drive parameter p1532 should be approximately
the same as the actual holding torque.
The specified torque for the brake test in MD $MA_SAFE_BRAKET-
EST_TORQUE must be set higher than the actual holding torque.
Clear the alarm with the Clear key or with NC–START.
Axis %1 brake test aborted, additional info %2
%1 = axis name, spindle number
%2 = fault information, based on $VA_FXS_INFO
The brake test has detected a problem. The additional information pro-
vides details of the cause of the alarm. An explanation is provided in
the documentation about the system variables $VA_FXS_INFO
Supplementary info:
0: No additional information available
1: Axis type is neither a PLC nor a command axis
2: Limit position reached, motion stopped
3: Abort using NC–RESET (key reset)
4: Monitoring window exited
5: Torque reduction rejected by drive
6: PLC has withdrawn the enable signal
Alarm display
Interface signals are set.
Note the supplementary conditions of the brake test, refer to supple-
mentary information.
Clear the alarm with the Clear key or with NC–START.
Axis %1 incorrect traversing direction brake test
%1 = axis name, spindle number
As a result of the selected traversing direction, the brake test is carried
out for the existing load torque with an incorrect torque.
Alarm display
– Carry out the brake test in the other traversing direction
– Adapt drive parameter p1532 more precisely to the actual situation.
This alarm only occurs – with the brake open – if the actual torque
deviates by more than 5% of parameter p1532
– Using MD $MA_SAFE_BRAKETEST_CONTROL, bit 0 = 1, activate
the automatic load torque determination at the beginning of the
brake test.
Clear the alarm with the Clear key or with NC–START.
