4.8 564 Ambienttemperature ENUM 40 degC 0 1 ERWZ FVS
Setting of the ambient temperature value. This parameter is used to set the output current derating factor (1% for
every °C above 40°C).
0 40 degC The inverter is capable of delivering direct current continuously with ambient temperatures of up
to 40°C.
1 50 degC The inverter is capable of delivering direct current continuously with ambient temperatures of up
to 50°C.
If the value is set to 1 the drive output current will be 10% less than the rated current at 40°C.

4.9 568 Switchingfreqmode ENUM Costant 0 1 ERWZS FVS
Setting of the switching frequency operating mode when drive overload is set in Heavy duty. The factory switching
frequency setting is 4 kHz for motors between 2.2 kW and 37 kW (the factory switching frequency setting for smaller
drives is 8kHz); this value may result in increased noise. Setting a higher switching frequency will increase drive
losses and thus increase the heatsink temperature, but it will also reduce noise. To combine the advantages of both
settings, with the ADV drive the heatsink temperature can be controlled by reducing the switching frequency if it
increases.
0 Costant
1 Variable
If set to Costant the switching frequency is xed and is set using the Switchingfrequency parameter, according to
the size of the drive. If the selected switching frequency value is higher than the default value, the output current of
the drive is derated.
If set to Variable the switching frequency is set to 8kHz and controlled by the temperature of the drive heatsink and
by the output frequency. If the heatsink temperature exceeds a set threshold (which depends on the size of the drive)
or falls to below 5Hz ± 1Hz, the switching frequency is automatically reduced to 4kHz, to prevent derating of the out-
put current. The switching frequency is reduced in a single step. Withthissettingtheswitchingfrequencyvalue
