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