Perpendicularity of flange attachment plane and
output shaft (A)
0.04mm
Eccentricity of flange fitting outer diameter (B) 0.04mm
Vibration of shaft end (C) 0.02mm
(Note) T.I.R : Total Indicator Reading
5) Impact resistance
The AC servo motor withstands two times of impacts with an
acceleration of 10G when up-and-down impacts are applied after
setting the motor shaft horizontally. However, a precision detector
is attached to the end of the shaft on the opposite side of the load,
take caution not to apply impact directly to this end.
6) Vibration resistance
The AC servo motor withstands a vibration
acceleration of 2.0G when vibration is applied in
up and down, left and right, and front and back
directions after setting the motor shaft horizontally.
7) Vibration grade
The vibration grade of the AC servo motor is V15 at the rated rpm.
8) Direction of installation
- Motor can be installed horizontally or at the top or bottom of the shaft.
- Keep the motor cable downward.
- If the motor is installed vertically, install a cable trap so that oils or water do not flow into
the motor.
