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 1.

Figure 1. Derating Depending on Drive Installation Method
  • L8-35 = 0 [IP20/UL Open Type] (0.5 m/s of airflow around the drive is necessary)
  • L8-35 = 1 [Side-by-Side Mounting]
  • L8-35 = 2 [IP20/UL Type 1]
  • L8-35 = 3 [External Heatsink/Finless]
