Temperature Derating
To ensure the maximum performance life, the drives output current must be derated like shown in Figure A.7 when the
drive is installed in areas with high ambient temperature or if drives are Side-by-Side mounted in a cabinet. In order to
ensure reliable drive overload protection, the parameters L8-12 and L8-35 must also be set according to the installation
conditions.
