The value of parameter
(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
SUPPLY or its source should be set to 0 (false).
Parameters 47.06...47.08
value of parameter 47.05 LOW VOLT MOD ENA
In the Low voltage mode, the default voltage control and trip levels as well as the
braking chopper operation levels (see sections
Braking chopper elsewhere in this chapter) are changed as follows:
Level
Supply voltage range
Overvoltage trip level
Overvoltage control level
Undervoltage control level
Undervoltage trip level
Braking chopper activation

Braking chopper maximum
power level
*Requires additional DC power supply JPO-01
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.
