52 Start-up with low voltage stator
The following figure represent synchronization at 1300 rpm speed (under speed synchronization).
06.08 STATOR Y FLUX is synchronized to 06.06 GRID Y FLUX and 06.07 STATOR U FLUX is
synchronized to 06.06 GRID U FLUX.
Check values of parameters 99.24 XM and 99.26 XM CALIBRATED.
If parameter values differ ±20%, stop the converter and change value
of 99.24 XM 20% towards the calibrated value. Restart the converter
and check the generator parameters and the stator current behavior
when the main circuit breaker is closed.

99.26 XM CALIBRATED
Enable the main circuit breaker function by setting parameter 21.02
DISABLE MCB CLOSE to NO. Check that the main circuit breaker
operates correctly.

Check the stator current measurement by giving a small torque
(25.04 TORQUE REF A) reference, eg, 15%. The current
measurement is correct if the actual torque value
01.02 GENERATOR TORQUE follows the given reference.
