1-2 Installation of spindle motor

CAUTION

1. Do not hold the cables, axis or detector when transporting the motor. Failure to

observe this could lead to faults or injuries.

2. Securely fix the motor to the machine. Insufficient fixing could lead to the

motor deviating during operation. Failure to observe this could lead to

injuries.

3. When coupling to a servomotor shaft end, do not apply an impact by

hammering, etc. The detector could be damaged.

4. Never touch the rotary sections of the motor during operations. Install a

cover, etc., on the shaft.

5. Do not apply a load exceeding the tolerable load onto the servomotor shaft.

The shaft could break. Failure to observe this could lead to injuries.

6. Do not connect or disconnect any of the connectors while the power is ON.

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.)
