4.6 Basic parameterization of the drive objects
Setting the line data and operating mode
The selection of the operating mode is displayed if you enter an operating voltage exceeding
415 V
1. Enter a value for the device supply voltage in the "Device supply voltage" field (p0210).
For a value exceeding 415 V, parameters for selecting the operating mode are displayed
(only ALM).
The following parameter data is determined automatically from the specified operating
voltage (ALM and SLM only) and displayed in the appropriate field:
– "Infeed DC-link voltage setpoint" (p3510)
– "DC-link voltage maximum steady-state" (p0280)
2. To activate the line/DC link identification, in the drop-down list "Supply/DC link
identification", select option "On".
If the line supply / DC-link identification has already been performed once, then the value
is preset to "OFF" (ALM and SLM only).
Selecting the operating mode
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)"

(ALM). The parameters are assigned default values when creating the device.
rms
(ALM).
rms
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.
