Note 1. *The values for items marked by asterisks are the values at an armature winding tempera-
ture of 20 ° C, combined with the Servo Driver. Other values are at normal conditions (20 ° C,
65%). The momentary maximum 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 position shown in the following di-
agram.
Radial load
End of Servomotor shaft
Note 6. Applicable Load Inertia
1) The drivable load inertia ratio (load inertia/rotor inertia) changes depending on the me-
chanical configuration 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 dy-
namic brake enabled.
