Derating

The derating condition is the reference value at the rated speed. As the temperature rise value of the rotary servo motor
changes depending on the operation conditions such as speed, confirm that [AL. 0E2 Servo motor overheat warning] or [AL.
046 Servo motor overheat] does not occur on the actual machine before use.
If [AL. 0E2 Servo motor overheat warning] or [AL. 046 Servo motor overheat] occurs, consider the following measures:
• Lower the effective load ratio of the rotary servo motor.
• Review the heat dissipation conditions.
To use this product under conditions with multiple derating, calculate the multiplication of each derating rate, and use at the
calculated derating rate or lower. For machines where unbalanced torque occurs, such as a vertical axis system, the
unbalanced torque should be kept at 70 % or lower of the rated torque. When applying the derating rate in the conditions
above, calculate the multiplication of the derating rate of 70 % in the unbalanced torque and the derating rate of each
condition, and use this product at the calculated derating rate or lower.

Restrictions on the flange size

When mounting the rotary servo motor on a machine smaller than the specified aluminum flanges listed in section 2.11, derate
the servo motor in accordance with the following conditions:
