● Break away Torque Check
The Break away Torque value during reverse rotation is judged .
When D-No. 110 [Reverse Torque High Limit] is exceeded, the fastening operation is
ended and an abnormal is output. (A09-08 “Reverse Torque Error”) The detection high
limit depends on the firmware version installed; (as shown in the table below)
