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.
