Defines a level of boost to apply to both linear and quadratic V/f curves according to the
following diagram

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.
