/DA/ Diagnostics instructions SINUMERIK 840D
/LH1/ SINAMICS S List Manual
Axis %1 illegal torque, current torque %2
%1 = axis name, spindle number
%2 = measured holding torque when selecting the brake test
The actually measured holding torque cannot be provided with the
existing parameterization of the brake test.
Alarm display
The function test of the mechanical brake system is aborted
The PLC block FB11 for the sequence control to test the mechanical
brake system is exited with a fault (fault detection = 2). This means that
the request – "start brake test" – isn't even effective for the axis.
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_BRAKETEST_TORQUE must be set higher than the
actual holding torque.
Clear the alarm with the Clear key or with NC-START.
