*1. These are the values when the Servomotor is combined with a Servo Drive at room temperature (20°C, 65%). The
maximum momentary torque shown above 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 Servomotor ON and 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 service life of 20,000 hours at normal operating
temperatures. The allowable radial loads are applied as shown in the following diagram.

*4. This is an OFF brake. (It is reset when excitation voltage is applied).
*5. The operation time is the value (reference value) measured with a surge suppressor (CR50500 manufactured by
Okaya Electric Industries Co., Ltd.).
