Thresholds

Lexium 62 Power Supply

o410 Vdc if BrakingResistorMode is set to 230 V mode / 0.

o850 Vdc if BrakingResistorMode is set to 400 V mode / 1 (default value).

The voltage threshold for this diagnostic message is only dependent on the parameter BrakingResistorMode. The parameter MainsVoltageMode has no influence on this threshold.
