●Break away Torque Check
Whether or not the torque value during reverse rotation is within the high limit ranges is judged. If the
torque exceeds the upper limit value, the fastening operation is ended and the abnormal state signal
A09-08 “Reverse Torque Error” is generated.
The upper limit value of the torque depends on the Controller software version and reverse rotation
operation. (See the table below)
