A.4 Drive Derating Data
u
Temperature Derating
To ensure the maximum performance life, the drive output current must be derated as shown in
installed in areas with high ambient temperature or if drives are mounted side-by-side in a cabinet. In order to ensure reliable
drive overload protection, set parameters L8-12 and L8-35 according to the installation conditions.

<1> Default setting is determined by drive model.
Setting 0: (Models 2A0250 to 2A0415 and 4A0208 to 4A1200)
Setting 2: (Models 2A0004 to 2A0211, 4A0002 to 4A0165, and 5A0003 to 5A0242).
Setting 0: IP00/Open-Chassis Enclosure
Drive operation between -10 °C and +50 °C allows 100% continuous current without derating.
Setting 1: Side-by-Side Mounting
Drive operation between -10 °C and +30 °C allows 100% continuous current without derating. Operation between +30 °C and
+50 °C requires output current derating.
Setting 2: IP20/NEMA 1, UL Type 1 Enclosure
Drive operation between -10 °C and +40 °C allows 100% continuous current without derating. Operation between +40 °C and
+50 °C requires output current derating.
Setting 3: External Heatsink Installation, Finless Drive
Drive operation between -10 °C and +40 °C allows 100% continuous current without derating. Operation between +40 °C and
+50 °C requires output current derating.
u
Altitude Derating
The drive standard ratings are valid for installation altitudes up to 1000 m. For installations from 1000 m to 3000 m, the drive
rated voltage and the rated output current must be derated for 0.2% per 100 m.
