4.6.8 Automatic transducer protections
To protect the transducer from overload a number of non-configurable restrictions are continuously
executed. The errors produced by these tests are always considered Fatal.
Transducer overload protection (Spindle Protection)
This test supervises that the torque measured on the monitoring channel does not exceed the maximum
allowed torque for the spindle. The measured torque must be less than Max Torque + 5% and Max
Torque + 5 Nm otherwise a transducer protection event is generated and error bit TPROT is set in the
Bolt level result variables "Errors"/"RM Errors".
