2. Glossary ① Tightening Torque: Output torque on completion of tightening. ② Tightening Pulses: The number of pulses between the display start torque and tightening completi on. ③ Work: A set of tightening points under the same tightening conditions. ④ WORK Start: The work selection input becomes start. With the group management function is on, when the work switching input is turned on, the remaining number of bolts is initiali zed and the group management starts.
⑪ SWITCH TRQ.: Torque at which middle speed is switched to high speed. ⑫ MIN. TRQ.: A lower limit value to make a judgment of OK/NOK. ⑬ CUT TRQ.: A torque value at which motor is automatically stopped while tightening. ⑭ MAX TRQ.: A upper limit value to make a judgment of OK/NOK. ⑮ FREERUNNING ANG: Angle between the point where a main shaft starts to rotate and the display start torque. ⑯ FINAL ANG: Angle between the display start torque and the tightening completion point.
27 SLOW ERR NO.: The number of pulses in excess of the preset number of pulses. Consequently, a slow error will result. 28 COMPEMC NUM: The number of pulses preset as compensation pulses, which will be performed after the display torque exceeds the cut torque, and the motor will be automatically stopped. 29 BOLT NUMBER: The number of tightening points of a single work with the group management function used. 30 PASS: The forced completion of work.
