Tightening sequence
In the FastApps mode, there is a choice between two tightening sequences:
•
Torque shutoff: Sequence 31 torque controlled, extended monitoring
Shut-off torque-controlled tightening sequence with torque and angle check.
Abb. 4-1: Representation of torque shutoff
•
Angle shutoff: Sequence 51 angle-controlled, extended monitoring
Shut-off angle-controlled tightening sequence with angle and torque check.
Abb. 4-2: Representation of angle shutoff
The following description applies to both tightening sequences.
For the speed, select a second speed parameter
Final speed
. If this is parameterized, the speed is reduced
from the starting speed to the final speed starting from the threshold torque to the maximum torque. The
final speed must be lower than the standard speed.
The angle counting starts when the
threshold torque
is reached.
After switching off via the
shut-off torque
/
shut-off angle
, the torque that develops or the associated angle is
compared with the
minimum/maximum torque
and the
minimum/maximum angle
and evaluated OK/NOK
accordingly.
The following parameters can be programmed in the particular FastApp configuration. See 3.7.1 Configur-
ing FastApps, Page 18 and 3.7.4 Advanced settings, Page 21.
