METHOD FOR STEPPING MOTOR DRIVING
PURPOSE:To make it possible to prevent the degradation of throughput of a motor, when moving to a constant velocity period at an intermediate point in an acceleration period before reaching the maximum velocity, by running a motor in such an acceleration/deceleration pattern that the length of the c...

| description | PURPOSE:To make it possible to prevent the degradation of throughput of a motor, when moving to a constant velocity period at an intermediate point in an acceleration period before reaching the maximum velocity, by running a motor in such an acceleration/deceleration pattern that the length of the constant velocity period differs from those of other constant velocity periods. CONSTITUTION:For cases where a motor moves to a constant velocity period at an intermediate point in an acceleration period to the maximum plotting velocity in short vector plotting by an X-Y plotter, the normal length of the constant velocity period is (t3-t1), and an acceleration/deceleration pattern of P1 is employed. In proximity to the attainment velocity V2 in an acceleration/ deceleration pattern of P2, the operation locus is vibratory much more than usual; therefore, the length of the patterns are so set that (t3-t1) |
