6-7. Fastening NG (Failure) Result Indications
When a fastening NG occurs, in addition to the NG lamp indication at the upper part of the controller, the
item detected as the fastening NG is indicated in the numerical value indication part by the present function.
In the case of fastening to the standard torque, judgments are made in the order: rate high/low limits,
differential angle high/low limits, 2ND region fastening high/low limit times, angle high/low limits, peak torque
high/low limits, and final torque high/low limits, and the item with which NG is detected first is indicated.
The following tightening NG items are not displayed in this function because they are
judged after tightening stops.
· Peak torque Low limit NG
· Final torque High limit NG
· Final torque Low limit NG
· Final angle Low limit NG
· DIFF angle High limit NG
· DIFF angle Low limit NG
· 1ST Time Low limit NG
· 2ND Time Low limit NG
· Rotating thread number lower limit NG
· SNUG Torque High limit NG
