Machine damage due to excessively high speeds
Excessive rotational speed can lead to serious damage to the machine. This can result in death,
serious injury or material damage.
• Avoid operation above the permissible speed by using the appropriate control function.
• Comply with the speeds stamped on the rating plate and in the electrical data.
5.8
System-inherent frequencies
Excessively high vibration levels and system resonances can damage the machine set.
• Configure and match the system consisting of the foundation and machine set in such a way
that no system resonances can arise and result in the permissible vibration levels being
exceeded.
• Do not exceed the vibration values according to DIN ISO 10816-3.

Electromagnetic compatibility
Note
Converter
• If operated with a frequency converter, the emitted interference varies in strength,
depending on the design of the converter (type, interference suppression measures,
manufacturer).
• Avoid that the specified limit values stipulated for the drive system (consisting of the motor
and converter) are exceeded.
• It is crucial that you comply with the EMC notes provided by the converter manufacturer.
• The most effective method of shielding is to conductively connect a shielded machine supply
cable to the metal terminal box of the machine (with a metal screw connection) over a large
surface area.
• On machines with integrated sensors (e.g. PTC thermistors), disturbance voltages caused by
the converter may occur on the sensor cable.
5.9.1
EMC and interference immunity
When used in accordance with their intended purpose, the enclosed machines comply with the
requirements of the current directive regarding electromagnetic compatibility.
