T = T1 + T2 + T3 + T4 T1: Acceleration time [s] Time until reaching the set speed T2: Constant speed time [s] Time while the actuator is operating at a constant speed T3: Deceleration time [s] Time from the beginning of the constant speed operation to stop T4: Settling time [s] Time until in position is completed = 0.1 + 1.57 + 0.1 + 0.3 = 2.07 [s] 500 500 500 mm or less T4 = 0.3 [s] 400
Time [s] Method 2: Calculation T1 T2 T3 T4 T5 Cycle time T can be found from the following equation. T6 T = T1 + T2 + T3 + T4 [s] Calculation example) T1 to T4 can be calculated as follows. L : Stroke [mm] V : Speed [mm/s] a1: Acceleration [mm/s2] a2: Deceleration [mm/s2] T1 and T3 can be obtained by the following equation.
T2 = [s] L 0.5 V (T1 + T3) V T = T1 + T2 + T3 + T4 = 0.1 + 0.57 + 0.1 + 0.2 T4: Settling time varies depending on the conditions such as motor types, load and in position of the step data. Therefore, calculate the settling time while referencing the following value. = 0.97 [s] T4 = 0.2 [s] Step 3 Check the allowable moment.
LEC Y T2 = [s] L 0.5V(T1 + T3) V T = T1 + T2 + T3 + T4 Motorless = 0.4 + 0.2 + 0.4 + 0.3 T4: Settling time varies depending on the conditions such as motor types, load and in position of the step data.
T4 = 0.05 [s] T1 = V/a1 = 300/5000 = 0.06 [s], T3 = V/a2 = 300/5000 = 0.06 [s] T2 = = = 0.94 [s] L 0.5 V (T1 + T3) V 300 0.5 300 (0.06 + 0.06) 300 T4 = 0.05 [s] Therefore, the cycle time can be obtained as follows.
= = 0.90 [s] T4 = 0.05 [s] T2 can be found from the following equation.
