APPENDIX
App. - 3
App. 4 Compliance with UL/CSA standard
POINT
When you conform HG-KN series servo motor to the UL/CSA standard as a
certified product by UL, the insulation class will be 105 (A). The insulation class
is approved for 130 (B) as for the UL/CSA standard by TÜV Rheinland.
Use the UL/CSA standard-compliant model of 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 standard-
compliant models are the same as those of the standard models.
The UL/CSA standard-compliant products are certified by UL and TÜV Rheinland. Their conditions of
certification may be different.
(1) Flange size
The 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 servo motor under the UL/CSA standard indicates the continuous permissible
torque value that can be generated when it is mounted on the flange specified in this table and used in
the environment of 0 °C to 40 °C ambient temperature. Therefore, to conform to the UL/CSA standard,
mount the servo motor on a flange with a heat radiating effect equivalent to that of this flange.
