6.4.14 Orientation Speed (S
ORT
: C2-11 and C3-11)
Make sure the Motor has stopped before setting the orientation speed.
The orientation speed settings are determined by the moment of inertia (including the Motor shaft), and
the torque. Consequently, calculate the load shaft moment of inertia and the load shaft torque when using
the H gear for each machine separately, and then determine the orientation speed by referring to the dia-
gram below. This speed is the upper limit, so the orientation speed can be set to a lower value than this one.
Formula
Load torque (Ts)
Note: Convert the load shaft torque us-
ing the gear ratio (load shaft/Motor
shaft) of the Motor continuous rated
torque.
