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.
Note: 3. Some Servo Drive parts will require maintenance. For details, refer to the G5 series USER'S MANUAL.
              Confirm the Manual No. that is listed in Related Manuals.

Note: 1. Do not use the cable when it is laying in oil or water.
Note: 2. Do not expose the cable outlet or connections to stress due to bending or the weight of the cable itself.
Note: 3. Always disconnect all connections to the Servo Motor before you perform insulation resistance tests on it. If you
             perform an insulation resistance test while the Servo Motor is connected, the Servo Motor may be damaged.
             Never perform dielectric strength tests on the Servo Motor. Failure to follow this precaution may result in

*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.
      2644_sp_9
*4. This is a non-excitation brake. (It is released when excitation voltage is applied.)
*5. The operation time is the value (reference value) measured with a surge suppressor (CR50500 by Okaya Electric
       Industries Co., Ltd.).

*1. These are the values when the motor is combined with a driver at normal temperature (20°C, 65%). The momentary

*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

*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.
