Interference Immunity; Influence On The Line Power Supply Through A Strongly Irregular Torque; Interference Voltages When Operating The Converter; Special Designs And Construction Versions - Siemens SIMOTICS GP series Operating Instructions Manual

Electromagnetic compatibility
This machine is designed in accordance with IEC/EN 60034, and when used as prescribed it
satisfies the requirements of European Directive 2014/30/EU on Electromagnetic
Compatibility.
2.6

Interference immunity

By selecting suitable signal cables and evaluation units, ensure that the interference
immunity of the machine is not diminished.
2.7 Influence on the line power supply through a strongly irregular
torque
A strongly irregular torque, for example with the drive of a reciprocating motor, forces a non-
sinusoidal motor current. The emerging harmonics can have an impermissible influence on
the line power supply via the connection lines.
2.8

Interference voltages when operating the converter

Interference voltages when operating the converter
When a converter is in operation, the emitted interference varies in strength depending on
the converter (manufacturer, type, interference suppression measures undertaken). On
machines with integrated sensors (e.g. PTC thermistors), interference voltages caused by
the converter may occur on the sensor lead. This can cause faults which can result in
eventual or immediate death, serious injury or material damage.
● Comply with the EMC information provided by the manufacturer of the converter. This is
how you prevent the limit values stipulated by IEC/EN 61000-6-3 for the drive system
(consisting of the machine and converter) from being exceeded.
● You must put appropriate EMC measures in place.

Special designs and construction versions

Note
Before carry out any work on the machine, determine the machine version.
If there are any deviations or uncertainty, contact the manufacturer, specifying the type
designation and serial number (see the rating plate), or contact the Service Center.
