1-2-2 Shaft characteristics

There is a limit to the load that can be applied on the motor shaft. Make sure that the load applied on the

radial direction, when mounted on the machine, is below the tolerable values given below. These loads

also affect the motor output torque, so consider them when designing the machine.

1-3 Installation of the control unit

CAUTION

1. Install the unit on noncombustible material. Direct installation on

combustible material or near combustible materials may lead to fires.

2. Follow the instructions in this manual and install the unit while allowing for

the unit weight.

3. Do not get on top of the units or motor, or place heavy objects on the unit.

Failure to observe this could lead to injuries.

4. Always use the unit within the designated environment conditions.

5. Do not let conductive objects such as screws or metal chips, etc., or

combustible materials such as oil enter the units.

6. Do not block the units intake and outtake ports. Doing so could lead to

failure.

7. The units and servomotor are precision devices, so do not drop them or apply

strong impacts to them.

8. Do not install or run units or servomotor that is damaged or missing parts.

9. When storing for a long time, please contact your dealer.

10. Always observe the installation directions. Failure to observe this could lead to

faults.

11. Secure the specified distance between the units and panel, or between the

units and other devices. Failure to observe this could lead to faults.

1-3-1 Environmental conditions

Environment Conditions

Ambient temperature 0°C to +55°C (with no freezing)

Ambient humidity 90%RH or less (with no dew condensation)

Storage temperature -15°C to +70°C (with no freezing)

Storage humidity 90%RH or less (with no dew condensation)

At mosphere

Indoors (no direct sunlight);

no corrosive gases, inflammable gases, oil mist, dust or conductive particles

Altitude

Operation/storage: 1000m or less above sea level

Transportation: 10000m or less above sea level

Vibration

Operation/storage: 4.9m/s

(0.5G) or less

Transportation: 49m / s

(5G) or less

(Note) When installing the machine at 1,000m or more above sea level, the heat dissipation

characteristics will drop as the altitude increases. The upper limit of the ambient

temperature drops 1°C with every 100m increase in altitude. (The ambient temperature at

an altitude of 2,000m is between 0 and 45°C.)

1-3-2 Installation direction and clearance

Wire each unit in consideration of the maintainability and the heat dissipation, as well as secure

sufficient space for ventilation.

CAUTION

The ambient temperature condition for the power supply unit or the drive units is

55°C or less. Because heat can easily accumulate in the upper portion of the

units, give sufficient consideration to heat dissipation when designing the panel.

If required, install a fan in the panel to agitate the heat in the upper portion of the

units.

1-3-3 Prevention of entering of foreign matter

Treat the cabinet with the following items.

• Make sure that the cable inlet is dust and oil proof by using

packing, etc.

• Make sure that the external air does not enter inside by

using head radiating holes, etc.

• Close all clearances.

• Securely install door packing.

• If there is a rear cover, always apply packing.

• Oil will tend to accumulate on the top. Take special

measures such as oil-proofing to the top so that oil does

not enter the cabinet from the screw holds.

• After installing each unit, avoid machining in the periphery.

If cutting chips, etc., stick onto the electronic parts, trouble

may occur.

• When using the unit in an area with toxic gases or high

levels of dust, protect the unit with air purging (system to

blow clean air so that the panel's inner pressure is higher

than the outer pressure).
