◆ Derating Depending on Ambient Temperature
When you install drives in these conditions, set L8-12 [Ambient Temperature Setting] and L8-35 [Installation
Method Selection].
• Surrounding air temperatures are higher than the rated conditions
• Install drives side-by-side in the enclosure panel
Derate the output current as specified in Figure 10.1.
A - L8-35 = 0 [IP20/UL Open Type] (0.5 m/s of
airflow around the drive is necessary)
B - L8-35 = 1 [Side-by-Side Mounting]
C - L8-35 = 2 [IP20/UL Type 1]
D - L8-35 = 3 [External Heatsink/Finless]
