7. Operation
[4] Moment
Check whether the operation is available by [2] moment, [4] acceleration, [5] loading capacity,
and [6] overhang.
Static moment (M1) calculation
Static moment equation
M1 = W x L x 9.8/1000 (Nm); L (mm): Distance from the operation point to load center of gravity
Stroke consideration: L = T + Hn + stroke (Patterns A and B)
No stroke consideration: L = T + Hn (Patterns C, D, and E)
Use Figure 2 and Table 2 to select an Hn measurement based on the installation orientation of the
load.

[3] Maximum speed, loading capacity
Check whether the operation is available by [3] maximum speed and [5] loading capacity.
AC Servo motor (RCA2) (Graph 1)
How to decide: You can use any model that has a [3] maximum speed and [4] loading capacity that is within
usage range in the graph.
