Note: 1. The above items reflect individual evaluation testing. The results may differ under compound conditions.
Note: 2. Always disconnect all connections to the Servo Drive before you perform insulation resistance tests on it. If you
              perform an insulation resistance test while the Servo Drive is connected, the Servo Drive may be damaged.
              Never perform dielectric strength tests on the Servo Drive. Failure to follow this precaution may result in
              damaging internal elements.

*1. These are the values when the motor is combined with a driver at normal temperature (20°C, 65%). The momentary
       maximum torque indicates　the standard value.
*2. Applicable load inertia.
      • The operable load inertia ratio (load inertia/rotor inertia) depends on the mechanical configuration and its rigidity.
        For a machine with high rigidity, operation is possible even with high load inertia. Select an appropriate motor and
        confirm that operation is possible.
      • If the dynamic brake is activated frequently with high load inertia, the Dynamic Brake Resistor may burn. Do not
        repeatedly turn the servo ON/OFF while the dynamic brake is enabled.
      • The dynamic brake is designed only for emergency stops. Design the system so that the Servomotor remains
        stopped for at least 3 minutes after applying the dynamic brake. Otherwise the dynamic brake circuits may fail.
*3. The allowable radial and thrust loads are the values determined for a limit of 20,000 hours at normal operating
       temperatures. The allowable radial loads are applied as shown in the following diagram.

*1. These are the values when the motor is combined with a driver at normal temperature (20°C, 65%). The momentary
       maximum torque indicates the standard value.
*2. Applicable load inertia.
      • The operable load inertia ratio (load inertia/rotor inertia) depends on the mechanical configuration and its rigidity.
         For a machine with high rigidity, operation is possible even with high load inertia. Select an appropriate motor and
         confirm that operation is possible.
     • If the dynamic brake is activated frequently with high load inertia, the Dynamic Brake Resistor may burn. Do not
        repeatedly turn the servo ON/OFF while the dynamic brake is enabled.
     • The dynamic brake is designed only for emergency stops. Design the system so that the Servomotor remains
        stopped for at least 3 minutes after applying the dynamic brake. Otherwise the dynamic brake circuits may fail.
*3. The allowable radial and thrust loads are the values determined for a limit of 20,000 hours at normal operating
        temperatures. The allowable radial loads are applied as shown in the following diagram.

*1. These are the values when the motor is combined with a driver at normal temperature (20°C, 65%). The momentary
      maximum torque indicates the standard value.
*2. Applicable load inertia.
      • The operable load inertia ratio (load inertia/rotor inertia) depends on the mechanical configuration and its rigidity.
         For a machine with high rigidity, operation is possible even with high load inertia. Select an appropriate motor and
         confirm that operation is possible.
      • If the dynamic brake is activated frequently with high load inertia, the Dynamic Brake Resistor may burn. Do not
         repeatedly turn the servo ON/OFF while the dynamic brake is enabled.
      • The dynamic brake is designed only for emergency stops. Design the system so that the Servomotor remains
         stopped for at least 3 minutes after applying the dynamic brake. Otherwise the dynamic brake circuits may fail.
*3. The allowable radial and thrust loads are the values determined for a limit of 20,000 hours at normal operating
       temperatures. The allowable radial loads are applied as shown in the following diagram.
