Abstract
PURPOSE: To shorten the time required for arrival at an indicated speed of a moving speed by performing speed control by frequency-dividing a pulse train of detection signals of a driving source variably.
CONSTITUTION: When contents of counter CNT1 and not changed considerably from an initial set value, position speed conversion circuit PSC sees contents counter CNT1 to operate switch SW1 for short-circuit across d and f. Therefore, a signal based on the value set in memory M is applied to D/A conversion circuit DA1, and a large power is given to driving source M2 to perform constant speed control. When contents of the counter becomes smaller, the position speed conversion circuit reduces the frequency division ratio of frequency divider circuit DiV according to contents, and the quantity of speed signals applied to subtractor SUB1 becomes larger. The value stored in memory M is determined within a range where amplifier AMP2 is not saturated for the value of forecastable moving speed, and this value is inputted to subtractor SUB1 through the D/A conversion circuit by the operation of the switch.
