■　Movement Principle of Electric Screwdriver Controller ( DO-1390A )

①Block chatr

②Electric current waveform

③Movement principle

Load current value of motor goes up as screw is fastened. Controller compares this value with the
preset one, and when the two values coincides, controller stops motors a determined time later.

④Reference

・ Load current is proportionate to fastening torque since DC motor is used.
・ Not to stop motor with starting current, the follwing condition is adopted. t1 < t2
・ Current detection level for I １ is set to 75% of I 0.
