PURPOSE:To prevent the cumulation of figure take-down errors and obtain an optional acceleration or deceleration pattern with high accuracy, by directly calculating an output from time factors on the basis of an acceleration pattern function or a deceleration pattern function. CONSTITUTION:When an acceleration signal or a deceleration signal is entered, an inverse operation t=f<-1>(x) or t=g<-1>(x) is effected in an acceleration pattern reversed function block 4 or a deceleration pattern reversed function block 5 on the basis of the output x of a device so far to determine an initial value tp at the beginning of acceleration or deceleration. The initial value is preset in a time counter 1, which adds sampling times DELTAtau to an initial time tp. An acceleration pattern function x=f(t) or a deceleration pattern function x=g(t) is determined in an acceleration pattern function block 2 or a deceleration pattern function block 3 from the output t of the time counter 1 and stored into a memory 10. |
