Description
Default
setup
P247
Socket release
Rotates the socket approximately three degrees backwards after the tightening
is done.
No
P250
Gradient monitoring
Monitors the torque increase or decrease for an angle window.
No
P251
Gradient torque min
Minimum increase of the torque for the angle window.
0
P252
Gradient torque
max
Maximum increase of the torque for the angle window.
9999
P253
Joint hardness
Hardness coefficient for the joint.
1- hard joint, 20- soft joint
10
P254
Start torque
Torque threshold where the gradient monitoring is to be started.
Start final
angle
P255
Angle offset
Additional angle from P254 Start torque before gradient monitoring is started.
0 deg
P260
Start torque
The torque threshold where the yield control is to be started.
Yield control is activated by selecting the P100 Control strategy
to Yield or Yield/Tq con (OR). The P101 Tightening strategy
can be set to One stage, Two stage or Quickstep, and yield
control will always interact in the second stage of the tightening.
P105 Zoom step strategy ending is disabled when yield control is
selected. An additional tightening angle can be added after the
yield point is reached by setting an angle to the P264 Extra
angle step parameter.
0.0 Nm
P261
Step angle
Defines the angle interval between the sample windows.
0 deg
P262
Window angle
Defines the length of the angle interval (the window) in which an average of
the torque values shall be calculated.
0 deg
P263
Yield slope ratio
This parameter decides the sensitivity of the yield point detection. The set
value is the percentage of the maximum slope, at which the yield point is
considered reached. 100% corresponds to the maximum slope during the
tightening (early shut-off and highest sensitivity), and 0% to a completely
horizontal portion of the trace (late shut-off close to or after peak torque).
50 %
P264
Extra angle step
Additional angle step after the yield point is reached.
0 deg
P280
Post view torque
Enable/disable the post view torque functionality. Only useful if torque is to
be measured during monitoring interval.
Some joints have a torque peak prior of P116 Rundown complete. Post view
torque function makes it possible to monitor torque values during two
specified angular intervals. The interval start is defined as angle prior to
rundown complete. Torque is then monitored for a specified angular interval.
Evaluation (OK/NOK) is done when rundown complete is reached.
Not accessible when any PVT-option is selected.
No
P281
Post view min
torque
Defines the low limit for the torque during the entire interval.
P110 Cycle
start
P282
Post view min
monitoring start
Start of min monitor interval.
9999
P283
Post view min
monitoring interval
Length of min monitor interval.
