Voltages specified for the smart mode are derived from the rectified line supply voltage. The DC link voltage setpoint

(p3510) has no effect in this control mode.

Voltage Sensing Module (VSM10) used with S120 Active Line Module

Using a Voltage Sensing Module (VSM10) to sense the line voltage, drives can also be

operated in systems with heavy frequency fluctuations beyond the range defined in

IEC61000-2-4 if specific conditions are met. Heavy 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 VSM10 Module is urgently

recommended.
The VSM10 Module helps to control extreme line faults, e.g. caused by thunderstorms or

rainstorms, without interruptions.

Commissioning

During commissioning, the device supply voltage (p0210) and the selection of an optional

line filter (p0220) must be parameterized.
After automatic commissioning, the relevant Wideband Line Filter 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

should be implemented using the line/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.

CAUTION

When an Active Interface Module is connected, it must be parameterized via p0220 = 4x

and the temperature sensor must be connected to X21 of the Active Line Module.

The DC link voltage (p3510) can be set within the following limits:
● Upper limit:

– Maximum DC link voltage (p0280)
– Product of line voltage (p0210) and max. step-up factor (r3508)

● Lower limit: Supply voltage (p0210) multiplied by 1.42
