Notes
♦ When using Continuous Boost P1310 together with other Boost Parameters
(Acceleration Boost P1311 & Starting Boost P1312) the Boost values are combined.
However priorities are allocated to these parameters as follows :
♦ P1310 > P1311>P1312
♦ The achievable boost value is limited by the setting in P0640.
♦ Increasing the Boost Levels increases the heating of the motor especially at standstill.
♦ Σ Boosts < 300/I
