Detuning could otherwise take very big values. this case, the
regulator adjusts the coil the undercompensation range until the Umax_End threshold
condition has been reached.
0 Self-extinguishing current limit
Moving the coil value lower than Umax_End threshold must limited.
Ex. one the limit values exceeded
in the tuning position, for example, the maximum continuous zero sequence voltage (priori-
ty 3), the regulator will search for new tuning position, whereby the target detuning can
no longer respected (priority ).
0 Umax_End Priority
Default value: No
If the function enabled, the value Umax_End must respected.0 A
Priority Limit values
1 Umax
2 Self-extinguishing current limit
3 Umax_End
4 Target detuning (v)
Based the above priorities, the regulator searches for tuning point without exceeding
theses predefined limit values the 'tuning position'.
A value disables the self-extinguishing current limit function
Default setting: 0. long the zero sequence voltage smaller than the set Umin threshold
during the search, the P-coil's whole adjustment range searched for position which
.: the coil close the upper end switch, might not possible reach the value of
Umax_End threshold with overcompensation (end switch kicks earlier).
This why smaller tolerance (compared with the default value Une_Tolerance) can set
for search trigger.
0 Umin_Threshold
Zero sequence voltages that are smaller than this limit value are interpreted measure-
ment noise.Page 113
Detailed description REG-DP/ REG-DPA parameters
0 Umax_End hysteresis
Une Umax_End hysteresis Umax_End threshold
During tuning, the coil moved until this value has been reached for Une (below the
Umax_End threshold)
A new search started when the Umax_End threshold has been exceeded
