2.5 Comparison of Moment of Inertia
POINT
As for the motor specifications not listed here, refer to the catalog or
Instruction Manual.
If the load inertia moment ratio is exceeded, please ask the sales
contact.
The symbols in the table mean as follows.
(B): With brake
(4): 400 V specifications
(H): Foot-mounting
The value in the parenthesis shows the value with brake.
(1) HF-KP series (With gears for general industrial machines with a reducer)
