◆ Temperature Derating
To ensure the maximum performance life, the drive output current must be derated as shown in Figure A.5 when the drive
is 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.
■ Parameter Settings
IP00 Enclosure
Drive operation between -10 °C and 50°C allows 100% continuous current without derating.
IP00 Enclosure with Top Protective Cover
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.

◆ Altitude Derating
The drive standard ratings are valid for an installation altitude up to 1000 m. If the altitude exceeds 1000 m both the drive
rated voltage and the rated output current must be derated for 1% per 100 m. The maximum altitude is 3000 m.
