■ Cautions after introducing the screwdriver and the
power supply.
Rotation speed of the screwdriver
● The rotation speed is different for forward and reverse rotations. Please refer to the values
on the specification of the screwdriver and the torque guide table only as rough guidelines.
● The rotation speed is measured without load. Please note the rotation speed varies when
the set value is 27 or more.
The controlled torque values are measured with the combination of a HIOS Torque Meter
HP-100 and a Fidaptor*. The values during your work are not always the same as the values
in the table. Please refer to the values in the table only as rough guidelines.
* For measuring torque with the screwdriver, use a fidaptor (accessory of HP-100), which
reduces and absorbs the inertia generated at stoppage and has the ability to reproduce
near-screw-fastening conditions to detect the torque when the clutch fires during
rotation of the screwdriver. Also, please use a dedicated torque measuring instrument,
HM Series, which can measure output torque of the screwdriver after it is installed.
■ Cautions when installing the screwdriver
● Note that screw fastening cannot be done with the screwdriver being installed upward.
● About the speed setting for screwdriver descending
If the descending speed of the Z-axis is faster than the screw fastening speed, screw floating
may occur due to overloaded tightening. Set the descending speed of the screwdriver
appropriate for the screw fastening.
● Consider the stiffness against Z-axis including the installation board of the screwdriver.
Note 1)
Please select Z-axis based on the following formula: Screwdriver
Installation angle weight = Tightening reaction force
Make sure to install the screwdriver with the above condition satisfied. (Please
contact us for details.)
Note 2) Please determine the thickness of the installation board tolerable with stiffness and
reaction force.
Guideline for the installation board thickness ・BLF-2000/BLF-5000: 8 mm or more
・BLF-7000 Series: 10 mm or more
● If the screw fastening cycle is short and constant torque is always required when a tapping
screw is fastened, it is necessary to check the required torque level by using an actual
machine. In such case, feel free to contact us.
● If the torque is high, presume that the reactive force against the screwdriver is strong and
the stiffness of the installation flange and Z-axis will impact on the screw fastening.
● Even if the above setting conditions are satisfied, overload may occur. In such case, review
the installation conditions.
● The flange and the main body of the screwdriver are fixed with left-handed screws.
