3.4 Initialization

Initialize the parameters use the following procedure. Set parameter b084 to "2" and parameter b180 to "1".

Neither the A044 or the b049 needs a initialization to become effective but some parameters could be changed automatically
when any of these parameters are modified.
This table shows the parameters that change when the dual rating selection is modified, remember that rated currents for heavy
and normal duty are different.
