Be careful as the fastening judgment is not performed regardless of the values of
the high and low limit set values when the settings of the fastening parameters
D-No. 003 “Judgment Item 1” and D-No. 004 “Judgment Item 2” are 0.
D-No. 003 Judgment Item 1 Target setting: 111101
*****1: Peak Torque Check Only the change 0 ￫ 1 is enabled.
･ Whether or not the peak torque during the fastening operation is within the range of the high and
low limit values is judged.
****1*: Final Torque Check
･ Whether or not the final torque at the end of the fastening operation is within the high and low limit
ranges is judged.
***1**: Final Angle Check Only the change 0 ￫ 1 is enabled.
･ Whether or not the final angle at the end of the fastening operation is within the high and low limit
ranges is judged.
The starting point of angle measurement is D-No. 107 [Snug Torque].
**1***: Rate 1 Check
･ Whether or not the torque slope from D-No. 112 [Rate 1 Start Torque] to D-No. 113 [Rate 1 End
Torque] is within the high and low limit ranges when D- No. 113 [Rate 1 End Torque] is attained is
judged.
*1****: Rate 2 Check
･ Whether or not the torque slope from D-No. 114 [Rate 2 Start Torque] to D-No. 115 [Rate 2 End
Torque] is within the high and low limit ranges when D- No. 115 [Rate 2 End Torque] is attained is
judged.
1*****: Rate 3 Check
･ Whether or not the torque slope from D-No. 116 [Rate 3 Start Torque] to D-No. 117 [Rate 3 End
Torque] is within the high and low limit ranges when D- No. 117 [Rate 3 End Torque] is attained is
judged.
