◆ Derating Depending on Ambient Temperature
When you install drives in a place where ambient temperatures are higher than the rated conditions or install drives
side-by-side in the enclosure panel, set L8-12 [Ambient Temperature Setting] and L8-35 [Installation Method
Selection]. Derate the output current as specified in Figure 5.1.
A - L8-35 = 0
B - L8-35 = 2, L8-35 = 3
C - L8-35 = 1

Ambient Temperature
Setting
Sets the ambient temperature of the drive installation area.
40 °C
(-10 °C - +50 °C)
The drive automatically adjusts the drive rated current to the best value as specified by the set temperature. Set the
ambient temperature of the area where you install the drive to a value that is more than the drive rating.
Refer to Derating Depending on Ambient Temperature on page 75 for information about derating depending on
ambient temperature.
