Hello,

There is no criteria can be defined for DC injection Level settings and DC injection time settings. The optimum level to be decided and fine tunned based on the requirement at site during commissioning. The DC current and time setting should be increased or decreased based on inertia of the load. It means, machine with higher inertia will require high DC current setting and the machine withe low inertia will require low DC current setting.

Please refer the attachment for the related parameters extract from programming manual.
