Battery charging characteristic

See function diagram 6720 in the SINAMICS DCP List Manual.
General information
A simple battery charging characteristic curve is available if the SINAMICS DCP is used as a
battery charging device.
Principle of operation
It is assumed that the battery is connected to side 2 of the DCP. A charging curve with 4
points (p51210/p54211) can be set. The SINAMICS DCP recharges the battery with the
current according to this characteristic curve. As soon as the highest point is reached,
recharging is ended and not restarted until a load has discharged the battery to such an
extent that the battery voltage has dropped by a settable value (p54212). The starting point
of the battery charging curve (r54221) must be defined as the current setpoint (p55050 =
r54221). The meaning of the setpoint should be set to "current on side 2" (p55060 =12).
