Note 1. If operation that generates torque more than 100% of the rating is performed with an abnormally high frequency in a servo
motor stop status (servo-lock status) or in a 50 r/min or less low-speed operation status, the servo amplifier may malfunction

10.2 Power supply capacity and generated loss
(1) Amount of heat generated by the servo amplifier
Table 10.1 indicates servo amplifiers' power supply capacities and losses generated under rated load.
For thermal design of an enclosed type cabinet, use the values in the tables in consideration for the
harshest conditions with regard to the environment and operation pattern. The actual amount of
generated heat will be intermediate between values at rated torque and servo-off according to the duty
used during operation. When the servo motor is run at less than the rated speed, the power supply
capacity will be smaller than the value in the table, but the servo amplifier's generated heat will not
change.
