this case, the
regulator adjusts the coil the undercompensation range until the Umax_End threshold
condition has been reached.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'.
This why smaller tolerance (compared with the default value Une_Tolerance) can set
for search trigger. 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

A value disables the self-extinguishing current limit function
Default setting: 0. 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 Self-extinguishing current limit
Moving the coil value lower than Umax_End threshold must limited.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.: the coil close the upper end switch, might not possible reach the value of
Umax_End threshold with overcompensation (end switch kicks earlier).
0 Umin_Threshold
Zero sequence voltages that are smaller than this limit value are interpreted measure-
ment noise.

Detuning could otherwise take very big values
