3-2 Servomotor Specifications
*1. These are the values when the Servomotor is combined with a Servo Drive at room temperature (20°C, 65%).
The maximum momentary 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 Servomotor ON and OFF while the dynamic brake is enabled.
*3. The allowable radial and thrust loads are the values determined for a service life of 20,000 hours at normal
3
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 manufac-
tured by Okaya Electric Industries Co., Ltd.).
