Operation at higher temperatures Most Emotron variable speed drives are designed for operation at maximum of 40°C ambient temperature. However it is possible to use the VSD at higher temperatures with little loss in performance. Table 6 shows ambient temperature as well as derating for higher temperatures. Operation at higher switching frequency Only valid for CDU. Table 7 shows the switching frequency for the different VSD models. With the possibility of running at higher switching frequency you can reduce the noise level from the motor. Table 7 Ambient temperature and derating for 400 –...

Environmental conditions * Brake output only available if the VSD is ordered with cable entry/exit at short end. Note: Cable glands are optional.
