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
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. and the SINAMICS
DC MASTER does monitor whether the overload duration that is actually permitted for the
power unit is being adhered to. For details on the power unit's dynamic overload
capability, refer to Chapter 10.
• The 100 % I
are reduced corresponding to the subsequent table.
