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.

*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 10 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. Direct current switching with a varistor (TNR15G271K by Nippon Chemi-Con Corporation or Z15D271 by Ishizuka
Electronics Co.).

*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 10 minutes after applying the dynamic brake. Otherwise the dynamic brake circuits may fail.

*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 10 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.
