Parameters for Four Step Tightening - Tightening Stage
The tightening step is divided into two steps, first step and final step. The First tightening step is from rundown complete until the First torque target level is reached. During the first tightening; time, torque and angle are monitored.
The graphical representation is used in the documentation to describe the configuration setting and the interpretation of the parameter values. The graphs are not used in any GUI.
A | Start of theFirst tightening step in the tightening step |
B | Min angle (monitor); Measured from First angle monitoring torque |
C | Max angle (monitor); Measured from First angle monitoring torque |
D | Maximum torque level (monitor) |
E | First tightening torque value; Defines the target value and the end of the step |
F | End of step |
G | Time max (monitor) |
H | Time min (monitor) |
J | Speed curve |
K | Torque curve and First angle monitoring torque reference point |
L | Minimum torque (monitor) |
Parameter | Description | Default value |
---|---|---|
First step | If the switch is in the Off position, the step is not executed and all other parameters are invisible and are ignored. | On |
First torque | Defines the target torque for the step. End of step is defined at this point, when the target is reached. | 20 Nm |
First speed | If Auto position, the speed is set automatically. If Manual position, the speed is set manually. | Auto |
First speed (parameter entry box) | This parameter entry box is only visible when Manual speed setting is selected. The spindle rotation speed during the step. | 345 rpm |
First torque min | Minimum torque value during the step. | 19 Nm |
First torque max | Maximum torque value during the step. | 21 Nm |
First angle monitoring torque | A specified torque value. From this point in time the angle monitoring starts. | 5 Nm |
First angle min | Minimum spindle rotation for the step. Measured from First angle monitoring torque. | 0 degree |
First angle max | Maximum spindle rotation for the step. Measured from First angle monitoring torque. | 500 degree |
Time min | Minimum time for the step. Measured from the start of the step. | 10 ms |
Time max | Maximum time for the step. Measured from the start of the step. | 500 ms |
Measure torque at | Max torque value Value at peak angle Value at shut off |
