Note 1. *The values for items marked by asterisks are the values at an armature winding temperature
of 100°C (for models of 750 W or less) or 20°C (for models of 1 kW or more), combined with
the Servo Driver. Other values are at normal conditions (20°C, 65%). The momentary maxi-
mum torque shown above indicates the standard value.
Note 2. The brakes are the non-excitation operation type (released when excitation voltage is ap-
plied).
Note 3. The operation time is the measured value (reference value) with a surge killer (CR50500, by
Okaya Electric Industries co. LTD) inserted.
Note 4. The allowable radial and thrust loads are the values determined for a service life of 20,000
hours at normal operating temperatures.
Note 5. The value indicated for the allowable radial load is for the positions shown in the diagrams
following the next table.
Note 6. Applicable Load Inertia
1) The drivable load inertia ratio (load inertia/rotor inertia) changes depending on the mechanical con-
figuration being driven and its rigidity. Highly rigid machines can operate with a large load inertia.
Select a Servomotor and verify operation.
2) If the dynamic brake is used frequently with a large load inertia, it may lead to burnout of the dynamic
brake resistor. Do not repeatedly turn the Servo ON and OFF with the dynamic brake enabled.
