Values smaller than min are invalid.

The coil started the opposite direction and reversed necessary the system can

of searches can reduced when the tolerance for slow changes adjusted.)

Note:
This setting makes sense the grid conditions are very unbalanced, meaning that there are
very high zero sequence voltages the resonance point. essentially impacts the tolerance range and the number identified
grid switches. the zero se-
quence voltage does not leave the tolerance field during the set time, the current zero
sequence voltage will adopted the new reference voltage the end this observa-
tion period.1. the measured value leaves this tolerance range
(due switching), the search aborted and new search started.
After the first estimate has been determined the falling edge, the direction changed
and new, normal search started the direction the resonance curve.

If the regulator displays 'Tune' and this parameter set, tolerance threshold placed

0 Une angle measurement
Parameters Description
YES angle measurement performed when the synchronization voltage con-
nected. The size the tolerance range does not change. The coil is
positioned the determined tuning point after the first estimate has been completed.
The parameter 'Exceed resonance peak' usually disabled,
meaning that the resonance point not exceeded unless has for tuning
