Automatic measurement of screw tightening time
When "DIP switch (SW) 5" is ON, the screw tightening time can be automatically measured.
1. When the MODE key [
] is pressed five times, [
] appears, and the "Screw Tightening Time" can be
measured.
2. Prepare the workpiece and screw with which the screw tightening time should be set, and carry out the actual screw
tightening process.
When a screw is tightened, the measured time appears on the display. This is the actual screw tightening time.
3. Then, turn the DIP switch 5 OFF. The actual screw tightening time is saved as the screw tightening upper limit time
[
].
4. As shown in the figure below, the screw tightening time is not constant, and varies several percent up and down
from this screw tightening time which has been saved by the above procedure. Thus, be sure to include the error
range (upper and lower than the actual screw tightening time) so that alarms are not emitted frequently.
* Refer to page 9 for details on setting the "screw tightening upper limit/lower limit time".
