Compliance with UL/CSA standard

Use the UL/CSA standard-compliant model of rotary servo motor. For the latest information of compliance, contact your local
sales office. Unless otherwise specified, the handling, performance, specifications, etc., of the UL/CSA compliant products are
the same as those of the standard models.

Flange size

The rotary servo motor is compliant with the UL/CSA standard when it is mounted on the flanges made of aluminum whose
sizes are indicated in the following table. The rated torque of the rotary servo motor under the UL/CSA standard indicates the
continuous permissible torque value that can be generated when the motor is mounted on the flange specified in this table,
and used in the environment of specified ambient temperature (0 °C to 40 °C). Therefore, to conform to the UL/CSA standard,
mount the direct drive motor on a machine with a heat radiating effect equivalent to that of this flange.
