APPENDIX
(10) Overload protection characteristics
An electronic thermal relay is built in the driver to protect the servo motor, driver and servo motor power line
from overloads. The operation characteristics of the electronic thermal relay are shown below. It is
recommended to use an unbalanced torque-generated machine, such as a vertical motion shaft, so that
unbalanced torque is not more than 70 of the rated torque. When you carry out adhesion mounting of the
driver, make circumference temperature into 0 to 45 (32 to 113 ) or use it with 75 or less of effective
load torque.
