3-3 Servomotor Specifications
*1. These are the values when the motor is combined with a drive 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.
 The dynamic brake is rated for short-term operation. Use it only for emergency stopping. Design the system to stop
for at least three minutes after the dynamic brake operates. Otherwise, the dynamic brake circuits may fail or the
dynamic brake resistor may burn.
*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.

*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.).
*6. Direct current switching with a varistor (Z15D151 by Ishizuka Electronics Co.).
*7. Direct current switching with a varistor (TNR9G820K by Nippon Chemi-Con Corporation).

Note:The continuous operation range is the range in which continuous operation is possible. Continuous operation at
the maximum speed is also possible. However, doing so will reduce the output torque.
