D-No. 110 Reverse Torque High Limit [N･m]
Setting range: 0 ~ D-No. 100 [Calibration Torque] × 1.3
The high limit value of the torque during reverse operation is set. When the reverse torque high
limit is exceeded during reverse operation, fastening is stopped and the abnormal state signal
A.09-08 “Reverse Torque Error” is generated.
♦Reverse Torque Judgment: [Neglect] •••
Manual reverse rotation by the PLC I/O input signal “REVERSE”
Reverse rotation operation by the lever on.
♦Reverse Torque Judgment: [Enable] •••
Reverse operation by the fastening option “Reverse After Fastening”
Reverse operation by the fastening option “Reverse Between 1-2 Steps”
Reverse operation by the fastening option “Reverse Between 2-3 Steps”
・ D-No. 110 [Reverse Torque High Limit] limit is caused when you loose the bolt already
fastened over 5N・m of default setting in the case of the reverse operation and it automatically
stops for safety.
D-No. 111 Torque Inhibit Limit [N･m]
Setting range: 0 ~ D-No. 100 [Calibration Torque] × 1.3
This is used to perform torque inhibition at the start of fastening. The torque inhibition is executed
from the start of fastening until D-No. 205 [Torque Inhibit Angle] is reached. If the starting torque
inhibit high limit is exceeded during the torque inhibition, the REJECT fastening judgment is made.
D-No. 112 Rate 1 Start Torque [N･m] D-No. 113 Rate 1 End Torque [N･m]
Setting range: 0 ~ D-No. 100 [Calibration Torque] × 1.0
The measurement start point and measurement end point of the torque rate 1 are set. The torque
slope (slope of torque vs. angle) from the rate 1 start torque to the rate 1 end torque is measured and
judged.
D-No. 114 Rate 2 Start Torque [N･m] D-No. 115 Rate 2 End Torque [N･m]
Setting range: 0 ~ D-No. 100 [Calibration Torque] × 1.0
The measurement start point and measurement end point of the torque rate 2 and the differential
angle are set. The torque slope (slope of torque vs. angle) from the rate 2 start torque to the rate 2
end torque is measured and judged.
D-No. 116 Rate 3 Start Torque [N･m] D-No. 117 Rate 3 End Torque [N･m]
Setting range: 0 ~ D-No. 100 [Calibration Torque] × 1.0
The measurement start point and measurement end point of the torque rate 3 are set. The torque
slope (slope of torque vs. angle) from the rate 3 start torque to the rate 3 end torque is measured and
judged.
