Abstract

PURPOSE: To make the target point approach within the threshold speed range by increasing the maximum control range of a phase detector more than that of a speed detector and setting the post-shift speed to the speed detection constant (window position) in a servo unit which uses digital technology.
CONSTITUTION: The revolution of controlled body, such as the motor 14 is detected by FG16 and PG20. The FG16 output is converted into the analog signal J by the DA converter 11 and applied to the motor 14 through the motor driving amplifier 24. The PG20 output is phase-compared with the reference phase input pulse of the terminal 22 and the output K of the phase detector is applied to the speed detector 10 as the window and shift signals. The maximum control range K of the phase detector becomes larger than that (J) of the speed detector. This permits high detection output to be obtained at transicent time.
