Note
•
If a value > 1 is set at p50067, you need to make sure that the "Dynamic overload
capability of the power unit" is enabled. This requires a value > 0 to be set at p50075.
•
The SINAMICS DC MASTER does not monitor whether the load class set using p50067
is being adhered to. If the power unit permits it, longer overload periods can be used than
those that correspond to the load class.
The actual permissible overload duration for the particular power unit is always greater
than the overload duration corresponding to the particular load class. SINAMICS DC
MASTER monitors whether the overload duration that is actually permitted for the power
unit is being maintained. For details on the power unit's dynamic overload capability, refer
to Chapter "Dynamic overload capability of the power unit (Page 591)".
•
The 100% I
DCx
shown previously DO NOT generally correspond to the rated unit current,
but are reduced according to the subsequent table.
