Abstract:
Disclosed is a command generation device capable of switching the averaging time of a moving average filter to any value without producing errors in the movement distance. The command generation device comprises: a speed command generation means (1) for outputting a speed command to an electric motor; a moving average filter (3) for calculating the moving average of the speed command; a movement distance correction amount calculation means (5) which receives a command for altering the averaging time of the moving average filter and calculates, in accordance with the speed command, the difference between the target movement distance and the movement distance calculated in accordance with the altered averaging time, as the movement distance correction amount; and a speed correction value calculation means (6) which uses the movement distance correction amount to calculate the speed correction value in accordance with the movement distance correction amount. The speed correction value is added to the moving average of the speed command and is set as an operation command for positioning control of the electric motor.
