SINUMERIK 840D sl/SINAMICS S120 SINUMERIK Safety Integrated (FBSI sl) – 03.2006 Edition
10.2 NCK safety alarms for Sinumerik 840D sl
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
provides 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6: PLC has withdrawn the enable signal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
supplementary info.
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.
Axis %1 is not safely referenced
%1 axis number
There are two reasons for this alarm:
– the user has still not acknowledged the machine position,
– the machine position has not yet been verified through follow-up
referencing.
Even if the axis is already referenced there is no acknowledgement that
referencing has supplied the correct result.
