5.6.1. Soft start ramp settings
It can be enabled in either phase control or pulse train
mode and controls the conduction angle.
It is enabled through the PS.E. parameter
The soft start ramp, always in Phase Angle, starts
from a conduction angle and reaches 100.0% in a
time set in the PS.tm parameter from 0.1 to 60.0 s.
Soft start ends before the defined time if the power
reaches the corresponding required value set in
manual control or calculated by the analog input.
The soft start ramp triggers at first start up after
power-on. It can be reactivated automatically if the
OFF condition occurs for a time longer than that
which can be set in PS.oF (if = 0 the function is as if it
were disabled).
