(*) these values depend on the type of installation
and are compatible with all the various types of sys-
tem.
(**) The noise level of the motor can be reduced us-
ing a frequency of 8 kHz. Increasing the switching
frequency reduces the capacity of the converter. It is
advisable to use a frequency of 4 kHz when the mo-
tor cable is long, in order to minimize the capacitive
currents in the cable.
WARNING:
Editing the parameters can cause the
converter to malfunction. Contact the as-
sistance service when modifications are
required.
