3.1.6.41 Motor-side grounding switch (option N45)
Under the following circumstances, operating modes can occur for which there is the danger
that the motor returns power to the converter:
● Operating mode / variant of the load machine, e.g. drive group with gas turbine
● Type of drive machine, e.g. permanently excited motor
resulting in hazardous voltages.
When the make-proof grounding switch is closed, this option allows motor-driven make-proof
grounding switches that ground the motor-side output voltage to be controlled automatically.
The motor-driven make-proof grounding switches are installed in an additional cabinet.
For safety reasons, the converter controller prevents the make-proof grounding switches from
being switched when voltage is still present. Activation is integrated in the protection and
monitoring sequence of the converter.
3.1.6.42 Power supply for auxiliaries 24 V DC/2.5 A (option N75)
The drive is delivered with a power supply unit for 24 V DC auxiliaries. It provides 6 output
terminals each for +24 V and 0 V. The total power consumption across all output terminals is
limited to 2.5 A.
3.1.6.43 Cell Bypass (option U11)
The drive system will automatically continue to operate uninterrupted if one or more cells have
a fault. The continuous current rating is maintained with faulted cells but at a reduced voltage.
Faulted cells can then be replaced at a convenient planned maintenance window.
3.1.6.44 Individual redundant cell (option U12)
This option permits the failure of an individual cell in the converter without the converter
identifying a fault or losing its full output capacity.
