Terminology Related to This Unit

Confirmation tightening (setting of the impact number)
To make sure if a screw has been tightened firmly, it is retightened two or three times after tightening. It is also
called double tightening or retightening.
Torque-up
When a screw is tightened completely and the tightening torque reaches the set torque, the clutch of the
automatic screwdriver disengages.
UP trigger
While the bit is rotating at high speed, this is used for an operational signal of the clutch that is received on the
uphill slope of the cam.
DOWN trigger
While the bit is rotating at low speed, this is used for an operational signal of the clutch that is received on the
downhill slope of the cam.
Input method
・ The signal input method of this unit uses a photo coupler. The maximum input current is 10 mA.
・ In case of an open collector connection, connect a collector to the input and GND to the emitter.
Note:
◦ Do not apply voltage to the input. Add a diode for reverse voltage absorption to the relay coil of the input contact.
◦When using an external device, take measures against noises.
Output method
The output signal of this unit uses a dry contact output common to internal GND on one side with the maximum
rated load being 24 VDC / 500 mA. Use GND as the common terminal when connecting an external device.
Note:
When a relay is connected to the output, add a diode for reverse voltage absorption. When using an external device,
take measures against noises.
Overload protection
This is to protect this unit and the automatic screwdriver.
If excessive current is generated in the motor due to overload to the working automatic screwdriver, the output is
stopped to protect the automatic screwdriver.
Abbreviations
The following product names used in this manual are abbreviated.
◦ Power supply dedicated for automatic brushless screwdriver → Power supply for automatic screwdriver
◦ Brushless screwdriver for automation → Automatic screwdriver or brushless screwdriver
◦ In the timing chart, the automatic screwdriver is referred as "screwdriver. "
◦ To indicate 3 models of BLF-7000, BLF-7000X and BLF-7025X → the BLF-7000 series
