Clear the alarm with the RESET key. Restart the part program.
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 actual parameterization of the function test of the mechani-
cal braking system:
-- The torque due to weight in drive parameter p1532 should be as far
as possible equal to the currently measured holding torque. The
measured holding torque is displayed in this alarm.
-- The holding torque for the brake test in MD $MA_SAFE_BRAKE-
TEST_TORQUE must be parameterized higher than the currently
set holding torque.
Clear the alarm with the Clear key or with NC--START.
