    • PROBLEM TO BE SOLVED: To provide a controller eliminating an error by acceleration deceleration control, and controlling velocity of each driving shaft being not in an orthogonal coordinate system such that the velocity, acceleration and jerk of each the driving shaft do not exceed respective maximum allowable values.
      SOLUTION: An instruction analysis part 11 analyzes a program, and a first interpolation part 12 finds an interpolation position in the orthogonal coordinate system on an operation path. A conversion part 13 performs conversion into a position of each the driving shaft being not in the orthogonal coordinate system. A tangent line direction acceleration calculation part 14 finds tangent line direction acceleration. A velocity limit calculation part 16 finds a velocity limit when arriving at each position wherein the velocity, acceleration and jerk of each the driving shaft do not exceed the maximum allowable values. A deceleration target velocity calculation part 17 finds deceleration target velocity when arriving at each the position. An intermediate memory 15 stores them. An acceleration deceleration processing part 18 finds a movement amount in a processing period in a second interpolation part 19. The second interpolation part 19 interpolates to perform output to a servo control part of each the driving shaft. By performing an acceleration deceleration process before the second interpolation, the error is eliminated.
