In the low voltage mode, the default voltage control and trip levels as well as the
brake chopper operation levels (see sections Voltage control and trip limits on page
161 and Brake chopper on page 161) are changed as follows:

Parameters Additional information
47.01 LOW VOLT MOD ENA Selects a signal source that enables/disables the low voltage mode.
47.02 LOW VOLT DC MIN Minimum DC voltage for the low voltage mode.
47.03 LOW VOLT DC MAX Maximum DC voltage for the low voltage mode.
47.04 BATTERY SUPPLY Selects a signal source that enables/disables external power unit supply,
used with low DC supply voltages such as a battery.
