Siemens SINAMICS S120 Function Manual page 27

The closed-loop controlled mode of booksize power units for p0210 > 415 V can be enabled
if the maximum stationary DC-link voltage (p0280) is increased as follows: p0280 ≥ 1.5 x
p0210 and p0280 > 660 V.
In this case, the setpoint of the DC-link voltage p3510 is not adapted automatically. p3510 =
1.5 x p0210 is recommended. The voltage-controlled operation is activated with p3400.0 = 0
and p3400.3 = 1.
Voltage Sensing Module 10 (VSM10) used with S120 Active Line Module
Using a "Voltage Sensing Module 10" (VSM10) to sense the line voltage, drives can also be
operated in systems with significant frequency fluctuations beyond the range defined in
IEC 61000-2-4 if certain supplementary conditions are met. Significant frequency fluctuations
may occur, e.g. in (isolated) diesel-electric systems but not in large interconnected systems
such as the European interconnected supply network.
In non-European countries, e.g. in countries with power distribution over a wide geographical
region
(countries with a large surface such as Australia, USA, China), line voltage dips occur more
frequently, the dips are somewhat lower and, above all, they can occur for longer periods of
time up to several seconds. In such line systems, the use of the Voltage Sensing Module is
urgently recommended.
Commissioning
During commissioning, the device supply voltage (p0210) and the selection of an optional
line filter (p0220) must be parameterized.
Following automatic commissioning, the appropriate filter for the matching Active Interface
Module is preset as the line filter. If the drive line-up is set up differently, then the line filter
type must be adjusted using p0220.
When it is first switched on with a new/modified network, an automatic controller setting must
be implemented using the line and DC-link identification routine (p3410).
Note
In a supply system without regenerative feedback capability (e.g. generators), regenerative
operation must be inhibited via the binector input p3533.
Note
When a Wideband Line Filter is connected, it must be parameterized with p0220 = 1...5. The
temperature sensor must be connected to terminal X21 of the Active Line Module.
The DC-link voltage (p3510) can be set within the following limits:
● Upper limit:
● Lower limit: Supply voltage (p0210) multiplied by 1.42
