Fig. 37:
● Using an S-curve gives the smoothest transition between speed changes. The acceleration and deceleration
curve adjusts the acceleration and deceleration S-curve. When enabled, the drive produces a different
acceleration and deceleration curve according to the acceleration and deceleration time.
● The S-curve function is invalid when you set the acceleration and deceleration time to 0.
● When Pr.01-12, 01-14, 01-16, 01-18 ≥ Pr.01-24 and Pr.01-25,
the actual acceleration time = Pr.01-12, 01-14, 01-16, 01-18 + (Pr.01-24 + Pr.01-25) / 2.
● When Pr.01-13, 01-15, 01-17, 01-19 ≥ Pr.01-26 and Pr.01-27,
the actual deceleration time = Pr.01-13, 01-15, 01-17, 01-19 + (Pr.01-26 + Pr.01-27) / 2.
