4 Cancelling the search
0 Max search cycles
This parameter describes the maximum number consecutive search cycles.
A search cycle consists the following regulator functions:
Starting the search, calculating the resonance curve, moving towards the end position and
comparing the reached position with the calculated position. The percent
value related the P-coil's Imax.5%).
Default setting: 1. the regula-
tor cannot find valid resonance curve within the set search cycles, the REG-DP places the
P-coil standby position.
Note:
When the coil backlash the overrun too big, increasing this value will prevent oscilla-
tions during positioning.
If the zero sequence voltage the end position does not correspond the calculated val-
ue curve could not determined for other reasons, the cycle considered have
completed unsuccessfully and new search cycle started.Page 103

0 Motor runtime max:
.
Default setting: 10
Note:
With current injection, repositioning search will consist least two search cycles.: 1*20% %
Note:
It can make sense disable this function for very small zero sequence voltages (value <
0. This
means that the default setting should not decreased combination with current
injection.5% inactive)

Default setting: inactive)
0 Positioning tolerance:
This parameter used set the tolerance for the positioning the P-coil.3. The type standby position set the parameter 'End posi-
tion cancel'
