Chapter 6 Fastening Operation
PAGE 6-66
D-No. 118 Final Torque Low Limit [N･m] Setting range: 0 ~ D-No. 100 [Calibration Torque] × 1.1
D-No. 119 Final Torque High Limit [N･m] Setting range: 0 ~ D-No. 100 [Calibration Torque] × 1.3
Sets the low and high limit values of the torque at the end of fastening.
･ If D-No. 000 [Fastening Method] is the “Torque Method,” the values of the final torque and the peak
torque will be equal - therefore set the same values as D-No. 101 [Peak Torque Low Limit] and
D-No. 102 [Peak Torque High Limit]. * Set values that differ only when D-No. 006 [After
Fastening Operation]: “Torque Recovery” is used.
･ If D-No. 000 [Fastening Method] is the “Angle Method,” set the low and high and limit values of the
fastening torque at the point at which the standard angle is reached.
(Note: it is common when using Angle Control that fastener yielding takes place. In this case, the
peak torque reports the highest torque seen during the fastening while the final torque would show
the (lower yielded) torque when the standard angle is met and fastening ends)
If the fastening torque exceeds the final torque high limit or falls below the final torque low limit, a
REJECT judgment is made.
D-No.120 Option [N•m]
Setting range: 0 ~ D-No. 100 [Calibration Torque] × 1.0
*Not used
D-No. 121 1 Pulse Reverse Torque High Limit [N･m]
Setting range: 0 ~ D-No. 100 [Calibration Torque] × 1.1
Sets the (Reverse) torque limit for the torque used in the D-No. 006 [1 Pulse Reverse] operation.
Normally, set this to be no more than half the standard torque (to ensure a pre-fastened fasteners
clamp load is not unloaded (or backed out))
