1.4 Servo motor installation
1.4.1 Installation environmental conditions

Working environment temperature: 0~40°C; working environment humidity: 80% or less (no
condensation).

Storage environment temperature: -40~50 °C; storage environment humidity: 80% or less (no
condensation).

Vibration: 0.5g or less.

A well ventilated place with less moisture and dust.

Non-corrosive, igniting gas, oil and gas, cutting fluid, cutting powder, iron powder and other
environments.

A place where there is no water vapor and direct sunlight.
1.4.2 installation method

Horizontal installation: To prevent water, oil and other liquid from flowing into the motor
from the motor outlet, place the cable outlet below.

Vertical installation: If the motor shaft is mounted upwards and the gear unit is attached,
care must be taken to prevent oil in the gear unit from penetrating into the motor through
the motor shaft.

The amount of protrusion of the motor shaft needs to be sufficient. If the amount of protrusion
is insufficient, it will easily cause vibration when the motor moves.

When installing and removing the motor, do not hit the motor with a hammer, otherwise the
motor shaft and encoder may be damaged.
1.5 Motor rotation direction definition
The motor rotation direction defined in this manual is defined as: facing the motor shaft
extension, the rotation axis rotates counterclockwise (ccw) for forward rotation, and the rotation
shaft rotates clockwise (cw) for reverse rotation.
