Specifications
*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.
*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).
