2.8
Interference immunity
By selecting suitable signal cables and evaluation units, ensure that the interference immunity
of the machine is not diminished.
2.9
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 limit values according to IEC/EN 61000-6-2 .... IEC/EN 61000-6-4 for the drive
system (consisting of the machine and converter) from being exceeded.
• You must put appropriate EMC measures in place.
2.10
Special designs and construction versions
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 (Page 12).
