D-No. 104 Ramp Down Start Torque [N･m]
Setting range: 0 ~ D-No. 100 [Calibration Torque] × 1.0
The torque value at which D-No. 401 [Freerun Speed] is switched to D-No. 402 [1st Speed] is set.
However, even if the ramp down start torque is not detected, switching to D-No. 402 [1st Speed] is
performed when D-No. 500 [Freerun Revolutions] is attained.
D-No. 105 1st Torque [N･m] Setting range: 0 ~ D-No. 100 [Calibration Torque] × 1.0
This is the end point of the 1st time from the start of fastening. The torque value at which D-No. 401
[Freerun Speed] or D-No. 402 [1st Speed] is switched to D-No. 402 [2nd Speed] is set. Switching to
D-No. 402 [2nd Speed] is also switched at the point at which the 1st torque or D-No. 203 [1st Angle]
is detected.
The 1st torque is also the point of synchronization in the 1st step in 2-step fastening and 3-step
fastening in the fastening sequence. If the 1st torque is not to be used in the fastening control,
input the same value as D-No. 100 [Calibration Torque].
D-No. 107 Snug Torque [N･m] Setting range: 0 ~ D-No. 100 [Calibration Torque] × 1.0
This is the start torque for angle measurement (this is the start point of angle measurement). If
D-No. 000 [Fastening Method] is the angle method, this is the start point of fastening. Angle
measurement and judgment are started from the Snug torque.
(Example: In case of Snug torque of 10N•m, D-No.202 [Standard Angle] of 90deg)
D-No. 108 Snug Torque High Limit [N･m]
Setting range: 0 ~ D-No. 100 [Calibration Torque] × 1.1
The high limit value of the start torque for angle measurement is set. If the value of D-No.107 [Snug
Torque] exceeds the Snug torque high limit, the REJECT fastening judgment is made.
D-No. 109 2nd Torque [N･m] Setting range: 0 ~ D-No. 100 [Calibration Torque] × 1.0
When the 2nd torque or D-No. 204 [2nd Angle] is detected during operation at D-No. 402 [2nd
Speed], switching to D-No. 403 [3rd Speed] is performed. The 2nd torque is also the point of
synchronization in the 2nd step in 3-step fastening in the fastening sequence.
If the 2nd torque is not to be used in the fastening control, input the same value as D-No. 100
[Calibration Torque].
