Primary functions and description of terms
1. Confirmation of tightening
•
To confirm that a screw is reliably tight and to perform additional tightening, tighten for
a 2nd and 3rd time after tightening for the first time. This is also referred to as second
tightening and additional tightening.
2. Torque-up
•
Refers to final tightening of the screw where the torque reaches the torque tightening
setting and the electric screwdriver clutch disengages.
•
This device defines the first torque-up after the normal rotation* count timer stops as
the torque- up for the finish of screw tightening. Set the count timer so that it does not
count down for torque-ups used for confirmation tightening.
* Normal rotation count timer is abbreviated to count timer in the rest of this document.
3. Input type
•
The signal input method for this equipment is a photo coupler input. The maximum
input current is of 10 mA.
•
When connecting an open collector, connect the collector to the input terminal and the
emitter to the GND terminal.
<Caution>
Do not apply voltage to the input terminals.
Add a diode or equivalent to relay coils that are connected to inputs to absorb reverse
voltage.
Provide some type of noise reduction measures when using external devices. (See Fig.
1, p. 20)
4. Output type
•
The signal output type for this equipment is an open collector output with a maximum
