Motor Protection Rating
Our servo motors comply with protection ratings of IEC standards (IEC 60529, IEC 60034-5) and JIS standards
(JIS C 0920, JIS C 4034-5).
The degree of protection (IP code) is defined by IEC (International
Electrotechnical Commission) 60529 Degrees of Protection Provided by
Enclosures (IP Code)
(IEC 60529)

1
Protection against solid objects > 50 mm
A spherical 50 mm diameter solid probe shall not completely penetrate
2
Protection against solid objects > 12.5 mm
A spherical 12.5 mm diameter solid probe shall not completely penetrate
3
Protection against solid objects > 2.5 mm
A spherical 2.5 mm diameter solid probe shall not penetrate at all
4
Protection against solid objects > 1 mm
A spherical 1 mm diameter solid probe shall not penetrate at all
5
Protection against a level of dust that could
hinder operation or impair safety
Although it is impossible to completely prevent the penetration of dust, there
should be no intrusion of an amount of dust that could impede the prescribed
operation and safety of the electrical equipment
6
Complete protection against dust

1
Protected against vertically falling drops of
water
Vertically dripping water shall have no harmful effect.
2
Protected against vertically falling drops of
water even if inclined up to 15
°
Vertically dripping water shall have no harmful effect when the enclosure is
tilted at an angle up to 15
°
from the vertical.
3
Protected against spraying water
Water falling as a spray at any angle up to 60
°
from the vertical shall have no
harmful effect.
4
Protected against splashing water
Water splashing against the enclosure from any direction shall have no harmful
effect.
5
Protected against water jets
Water projected by a nozzle against enclosure from any direction shall have no
harmful effects.
6
Protected against powerful water jets
Water projected in powerful jets against the enclosure from any direction shall
have no harmful effects.
7
Protected against temporary immersion in
water
Ingress of water in harmful quantity shall not be possible when the enclosure is
immersed in water under defined conditions of pressure and time.
8
Protected against submersion in water
The equipment is suitable for continuous immersion in water under conditions
which shall be specified by the manufacturer. The test conditions are expected to
be greater than the depth requirements for IPx7, and other environmental effects
may be added.

Note 1: The standard states that the liquid used for testing should be fresh (pure) water, and liquids other than water such as oil are not included in the test
conditions. Separate evaluation is necessary when used in environments subjected to non-water liquids, e.g., where machine tool cutting oil is present.
Our servo motors have a proven track record of optional customization for machine tool applications, so please contact us as necessary.
Note 2: The ratings for water ingress (second digit) are not cumulative beyond IPX6. A device that is compliant with IPX7 (covering immersion in water) is not
necessarily compliant with IPX5 or IPX6 (covering exposure to water jets). Select a protection rating suitable for your environment.
