SINUMERIK 840D sl/SINAMICS S120 SINUMERIK Safety Integrated (FBSI sl) - - 10.2015 Edition
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: Interrupted by an axis RESET (DB31--61, DBB28 bit1)
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6: PLC has withdrawn the enable signal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 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 a brake test in the other traversing direction
-- Adapt drive parameter p1532 more precisely to the actual situation.
This alarm only occurs if the actual torque deviates by more than
7.5% of SINAMICS 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.
Channel %1 Block %2 motion- -synchronous action: Index invalid
%1 = channel number
%2 = block number
An invalid index was used when accessing a variable in the motion--
synchronous action.
Example: ...DO $R[$AC_MARKER[1]] = 100
The error occurs if marker 1 has a higher value than the maximum
permissible R--parameter number.
