Doing so may result in injury.

yProvide a cover over the rotating part (output shaft) of the motor.

Failure to do so may result in injury.

yUse a motor and driver only in the specied combination.

Failure to do so may result in re.

yProvide an emergency stop device or emergency stop circuit so that the

entire equipment will operate safely in the event of a system failure or malfunction. Failure to do so may result in injury.

yWhen an abnormal condition has occurred, immediately stop operation

and turn o the driver power. Failure to do so may result in re or injury.

yThe motor surface temperature may exceed 70 °C (158 °F)

even under normal operating conditions. If the operator is allowed to approach the running motor, attach a warning label as shown below in a conspicuous position. Failure to do so may result in a skin burn(s).

label

Precautions for use

•When conducting the insulation resistance measurement and the dielectric strength test, be sure to separate the connection between the motor and the driver.

Conducting the insulation resistance test or dielectric strength test with the motor and driver connected may result in damage to the product.

•Do not apply a radial load and axial load in excess of the specied permissible limit

Operating the motor under an excessive radial load or axial load may damage the motor bearings (ball bearings). Be sure to operate the motor within the specied permissible limit of radial load and axial load.

•Motor surface temperature

The surface temperature on the motor case may exceed 100 °C (212 °F) depending on operating conditions such as ambient temperature, operating speed, duty cycle and others. To prevent the motor bearings (ball bearings) from reaching its usable life quickly, use the motor in conditions where the surface temperature will not exceed 100 °C (212 °F).

•Holding torque at standstill

The motor holding torque is reduced by the current cutback function of the driver at motor standstill. When operating the motor, take account of the motor torque drop at the time of stopping.

Installation

Location for installation

The motor is designed and manufactured for installation in equipment. Install it in a well-ventilated location that provides easy access for inspection. The location must also satisfy the following conditions:

yInside an enclosure that is installed indoors (provide vent holes) yOperating ambient temperature −10 to +50 °C (+14 to +122 °F) (non-freezing) yOperating ambient humidity 85% or less (non-condensing) yArea that is free of explosive atmosphere or toxic gas (such as sulfuric gas) or liquid yArea not exposed to direct sun yArea free of excessive amount of dust, iron particles or the like yArea not subject to splashing water (rain, water droplets), oil (oil droplets) or other

liquids

yArea free of excessive salt yArea not subject to continuous vibration or excessive shocks yArea free of excessive electromagnetic noise (from welders, power machinery, etc.) yArea free of radioactive materials, magnetic elds or vacuum y1,000 m (3,300 ft.) or lower above sea level

Installation method

Install the motor onto an appropriate at metal plate having excellent vibration resistance and heat conductivity. When installing the motor, secure it with four bolts (not supplied) through the four mounting holes provided. Do not leave a gap between the motor and metal plate.

Secure the lead wires at the connection part to prevent the connection part from receiving stress due to the exing of the lead wires or the lead wires’ own mass. Also, do not excessively bend the lead wires near the connection part of the connector. Applying stress on the motor lead wires may cause poor contact or disconnection, leading to malfunction or heat generation.
