Torque Check [N•m]
•Peak Torque
The high and low Peak Torque limit values during fastening on are set. Fastening operation is ended if the
peak torque high limit value is exceeded during fastening operation. (Peak Torque is the control point in
TORQUE CONTROL)
•Final Torque
The high and low Final Torque limit values of the fastening torque at the point at which the standard angle is
attained are set. (Final Torque is the final torque recorded at the point Standard Angle is attained in
ANGLE CONTROL)
•Snug Torque
The high limit value of Snug torque is detected when Snug Torque Detection is set.
•Torque Inhibit
The Torque Inhibit high limit value after the start of the fastening operation is set. This can be used for
fastening in cases where the starting torque is higher than your targeting torque. The fastening operation
is ended when, during operation within D-No. 205 [Torque Inhibit Angle], the start torque inhibit high limit
value is exceeded.
Additionally, from the start of fastening to the point at which D-No. 205 [Torque Inhibit Angle] is attained,
torque-related set values besides the starting torque inhibit high limit are ignored.

•When the Torque Inhibit check is enabled, the following set values are ignored within the Torque
Inhibit Angle from the start of fastening.
D-No. 103: Standard Torque, D-No. 104: Ramp Down Start Torque, D-No. 105: 1st Torque, D-No.
107: Snug Torque, D-No. 109: 2nd Torque, D-No. 112: Rate 1 Start Torque, D-No. 113: Rate 1
End Torque, D-No. 114: Rate 2 Start Torque, D-No. 115: Rate 2 End Torque, D-No. 116: Rate 3
Start Torque, and D-No. 117: Rate 3 End Torque.
