G5-series AC Servomotors and Servo Drives User’s Manual (with Built-in EtherCAT Communications)
*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 intended for emergency stop and therefore has a short-time rating.
If the dynamic brake is activated, allow it to be in a stop state for 3 minutes or more to prevent a circuit failure
and burning of the Dynamic Brake Resistor.
*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.).
