Selection Example
Step 1
Check the speed–work load.
Step 2
Check the cycle time.
Step 3
Check the allowable moment.
• Work load: 60 [kg]
• Speed: 300 [mm/s]
• Acceleration/Deceleration: 3000 [mm/s2]
• Stroke: 300 [mm]
• Mounting orientation: Horizontal
• Motor type: Incremental encoder
• External force: 10 [N]
• Workpiece mounting condition:

<Dynamic allowable moment>
(LEJS63)
Step 1
Check the speed–work load.
Select the product by referring to “Speed-Work Load Graph” (Page 12).
Selection example) The LEJS63S3B-300 is temporarily selected based on the
graph shown on the right side.
The regeneration option may be necessary.
Refer to page 12 for “Required Conditions for Regeneration Option”.
Step 2
Check the cycle time.
Method 2: Calculation
Refer to method 1 for a rough estimate, and method 2 for a more precise value.
Cycle time T can be found from the following equation.
Method 1: Check the cycle time graph (Page 13)
The graph is based on the maximum speed of each size.
T = T1 + T2 + T3 + T4 [s]
T4 = 0.05 [s]
T1 = V/a1 [s] T3 = V/a2 [s]
T2 = [s]
L − 0.5 · V · (T1 + T3)
V
• T4 varies depending on the motor type and
load. The value below is recommended.
•
T2 can be found from the following equation.
• T1 and T3 can be obtained by the following equation .
The acceleration and deceleration values have upper limits
depending on the workpiece mass and the duty ratio.
Check that they do not exceed the upper limit, by referring
to “Work load–Acceleration/Deceleration Graph (Guide)”
(Pages 15 to 17).
For the ball screw type, there is an upper limit of the speed
depending on the stroke. Check that if it does not exceed
the upper limit, by referring to the specications (Page 26).
Step 3
Check the allowable moment.
L : Stroke [mm]
V : Speed [mm/s]
a1: Acceleration [mm/s2]
a2: Deceleration [mm/s2]
Duty ratio: Ratio of T to T6
T ÷ T6 x 100
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
T5: Resting time [s]
Time the product is not running
T6: Total time [s]
Total time from T1 to T5
Calculation example)
T1 to T4 can be calculated as
follows.
T1 = V/a1 = 300/3000 = 0.1 [s],
T3 = V/a2 = 300/3000 = 0.1 [s]
T4 = 0.05 [s]
Therefore, the cycle time can be
obtained as follows.
T = T1 + T2 + T3 + T4
= 0.1 + 0.90 + 0.1 + 0.05
= 1.15 [s]
T2 =
=
= 0.90 [s]

Model Selection
Refer to “Dynamic Allowable Moment” graphs (Pages 18 and 19).
Selection example) Select the LEJS63S3B-300 from the graph on the right side.
Conrm that the external force is 20 [N] or less.
(The external force is the resistance due to cable duct, exible trunking or air tubing.)

15,000 mm/s2
10,000 mm/s2
20,000 mm/s2
1. Decide operating conditions.
Model: LEJS/LEJB
Size: 40/63
Mounting orientation: Horizontal/Bottom/Wall/Vertical
2. Select the target graph with reference to the model, size and mounting orientation.
3. Based on the acceleration and work load, obtain the overhang [mm]: Lx/Ly/Lz from the graph.
4. Calculate the load factor for each direction.
αx = Xc/Lx,αy = Yc/Ly,αz = Zc/Lz
5. Confirm the total of αx, αyand αzis 1 or less.
αx + αy + αz ≤1
When 1 is exceeded, please consider a reduction of acceleration and work load, or a
change of the work load center position and series.
3. Lx = 180 mm,Ly = 170 mm,Lz = 360 mm
4. The load factor for each direction can be obtained as follows.
αx = 0/180 = 0
αy = 50/170 = 0.29
αz = 200/360 = 0.56
5. αx + αy + αz = 0.85 ≤1
