haracteristics
*1. This is a typical value for when the Servomotor is used at a normal temperature (20°C, 65%) in combination with a Servo
Drive.
*2. The rated values are the values with which continuous operation is possible at an ambient temperature of 40°C when
the Servomotor is horizontally installed on a specified radiator plate.
*3. This value is for models without options.
*4. The allowable radial and thrust loads are the values determined for a limit of 20,000 hours at normal operating tempera-
tures.
