*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.
