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.

Four step tightening - parameters in the first step of the tightening step

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)

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
