5.6.1.3. Softstart
This type of start-up can be enabled in BF, PA and
HSC mode (for versions with type AN or I control).
In the case of phase control, the increase in the
conduction angle q stops at the corresponding value
of the power to be transferred to the load.
When the load shut-off time (settable) is exceeded,
the ramp is reactivated at the next power-on.
