• Differential Torque
Input of the differential final torque
The actual target torque - results from the sum of the determined friction torque and
the differential moment
o Minimum differential torque
Lower limit of the differential final torque. The actual torque lower limit results
from the sum of the lower limit of the friction torque and the lower limit of the
differential torque.
• Maximum differential torque
Upper limit of the differential final torque. The actual torque upper limit results from
the sum of the upper limit of the friction torque and the upper limit of the differential
torque.
• Torque hold time
A holding time can be defined to keep tension applied to the screw joint for a preset
time to allow for material elasticity.
• End value creation: Differential torque / total torque
Selectively the end torque can be displayed as difference between the total torque
and the torque of the previous sequence step or as total torque in the final values.
• Angle monitoring: yes / no
Monitoring of the angle with a window angle if the angle monitoring is switched on,
the following parameters are added:
◦ Angle upper limit
Upper limit of the end angle. The value counts starting from the end of the friction
measurement.
◦ Angle lower limit
Lower limit of the end angle
The value counts starting from the end of the friction measurement.
