Step 2 Check the cycle time. 晋orkpiece mass: 16 [kg] 心peed: 300 [mm/s] 植cceleration/Deceleration: 5,000 [mm/s2] 心troke: 300 [mm] 晋orkpiece mounting condition: Vertical upward downward transfer Operating conditions Selection Procedure Positioning Control Selection Procedure Selection Example Step 1 Check the work load.speed. (Vertical transfer) Step 2 Check the cycle time. Calculate the cycle time using the following calculation method. 燭ycle time T can be found from the following equation. Select the target model based on the workpiece mass and speed with reference to the . Selection example) The LEY25ョB is temporarily selected based on the graph shown on the right side. T = T1 + T2 + T3 + T4 [s] T1 = V/a1 [s] T4 = 0.05 [s] T3 = V/a2 [s] T2 = [s] L . 0.5 ・ V ・ (T1 + T3) V 慎4: Settling time varies depending on the conditions such as motor types, load and in positioning of the step data. Therefore, please calculate the settling time with reference to the following value. 慎2: Constant speed time can be found from the following equation. 慎1: Acceleration time and T3: Deceleration time can be obtained by the following equation. L : Stroke [mm] ... (Operating condition) V : Speed [mm/s] ... (Operating condition) a1: Acceleration [mm/s2] ... (Operating condition) a2: Deceleration [mm/s2] ... (Operating condition) 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 Calculation example) T4: Settling time [s] ... Time until in position is completed T1 to T4 can be calculated as follows. T1 = V/a1 = 300/5000 = 0.06 [s], T3 = V/a2 = 300/5000 = 0.06 [s] T4 = 0.05 [s] Therefore, the cycle time can be obtained as follows. T = T1 + T2 + T3 + T4 = 0.06 + 0.94 + 0.06 + 0.05 = 1.11 [s] T2 = = = 0.94 [s] L . 0.5 ・ V ・ (T1 + T3) V 300 . 0.5 ・ 300 ・ (0.06 + 0.06) 300 W (LEY25ョ) . It is necessary to mount a guide outside the actuator when used for horizontal transfer. When selecting the target model, refer to pages 192, 199 and 204 for the horizontal work load in the specifications, and page 219 for the precautions. Based on the above calculation result, the LEY25ョB-300 is selected. Electric Actuator/Rod Type Series LEY/LEY-X5 Model Selection The regeneration option may be necessary. Refer to pages 186, 187 and 189 for “Required Conditions for Regeneration Option”. AC Servo Motor Size 25, 32 Dust/Drip Proof (IP65) Specification A 184
