CVIC II

9.3 - Angle control and torque monitoring

For CVIC II this strategy allows to rotate by N degrees a
bolt over the angle threshold.

9.4 - Prevailing torque control

This phase allows you to check the residual torque
(prevailing torque) that results, for instance from the
thread formed with tapping screws.
It is useful to know if the thread is formed correctly
during the desired number of rotations without untimely
locking or tapping deficiency.
The initial time out allows you to start the readings when
the tool speed is stabilised.
The memorised result is the mean of the torque readings
during the acquisition phase.
The system stops the acquisition of the torque and angle
when the motor stops.
The torque pulse at the motor stop is not taken into
account.
