1. The calculation of 'estimated speed'.
2. Used by the rotating autotune function to determine the speed levels for measuring the field saturation breakpoints.
3. Used to determine the speed used in the auto tuning inertia test (see Pr 5.12 { SE13, 0.34 }).
A value of 165° corresponds to the fully phased back condition and therefore zero output voltage.
A value of 0 in the firing angle Pr 5.10 corresponds to fully
phased forward and therefore maximum output voltage.
WARNING
since it allows the drive to operate without the influence of either the speed loop or the current loop, thereby eliminating their effect upon the system.
This parameter must be used with caution. When the firing
angle is controlled directly by Pr 5.10 there is no protection
against excessive acceleration, output voltage or current
WARNING
other than the instantaneous over current trip. Also take care
to reset Pr 5.11 to 0 after the completion of tests.
