The value of parameter 47.08 EXT PU SUPPLY or its source should be set to 1
(true) when a supply below 270 V DC – such as a battery – is used. In such a
configuration, an additional DC power supply (JPO-01) is needed to power the main
circuit electronics. With an AC supply, the value of parameter
47.08 EXT PU
SUPPLY or its source should be set to 0 (false).
Parameters 47.06 … 47.08 are effective only when the Low voltage mode is active, ie,
value of parameter 47.05 LOW VOLT MOD ENA (or its source) is 1 (true).
In the Low voltage mode, the default voltage control and trip levels as well as the
braking chopper operation levels (see sections
Voltage control and trip limits and
Braking chopper elsewhere in this chapter) are changed as follows:
Different system configurations are detailed in ACSM1 System Engineering Manual
(3AFE68978297 [English]).
Note: The Low voltage mode is not available for frames E to G.
