Product Description:
Also the thyristor diagnosis provided by the firmware can be used:
-Switch the drive to local mode (DriveWindow, DriveWindow Light, DCS Control
Panel or local I/O).
-Start the thyristor diagnosis by means of ServiceMode (99.06) = ThyDiagnosis
and set On and Run within 20 s.
-During the thyristor diagnosis the main contactor will be closed and the
thyristors are checked. The field current is not released while the thyristor
diagnosis is active and thus the motor should not turn.
The ripple monitor indicates that the ripple of the DC current is much higher than
normal. In such a case, most often one thyristor does not work. It’s missing current
contribution causes a deep dip in the direct current.
