Setting the line data and operating mode
The parameters in this screen form are assigned default values when creating the device.
1. Enter a value for the device supply voltage in the "Device supply voltage" field (p0210).
2. To activate the line/DC link identification, in the drop-down list "Supply/DC link
identification", select option "On".
Selecting the operating mode for ALM
The operating mode depends on the motor voltage.
Example: The DC-link voltage must be lower in the USA. For this reason, you can switch the
mode of an Active Line Module in order to be able to use it as a Smart Line Module (Smart
Mode). You can set the operating mode in this screen form for operating voltages greater
than 415 V
1. Set one of the two operating modes:
– "Vdc non-regulated (Smart Mode)"
– "Vdc regulated (Active Mode)"

In Smart Mode, the regenerative capability is maintained, but this results in a lower
DC-link voltage compared to Active Mode. The DC-link voltage depends on the
current supply voltage.
In Active Mode, the DC-link voltage is regulated to a settable setpoint (p3510) to
produce a sinusoidal supply current (cos φ = 1). The size of the reactive current is also
regulated and can be set specifically.

x - If the line supply / DC-link identification
has already been performed once, then
the value is preset to "OFF".
