Noise Emissions; Rotational Speed Limit Values; Voltage And Frequency Fluctuations During Line Operation - Siemens SIMOTICS FD 1LH1 Operating Instructions & Installation Instructions

The weight of the machine is stated on the rating plate, data on geometry is shown in the
dimension drawing.
Missing support at the NDE
If the machine has no additional support at the NDE, the flange cannot hold the weight of the
machine. The machine or machine parts may loosen.
This can result in death, serious injury or material damage.
Use an appropriately sized support base.

Noise emissions

Noise emissions
During operation, the machine's noise emission levels can exceed those permitted at the
workplace, which can cause hearing damage.
Take steps to reduce noise, such as introducing covers and protective insulation or adopting
hearing protection measures, so that the machine can be operated safely within your system.
4.12

Rotational speed limit values

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.
● Observe the speeds stamped on the rating plate.
4.13

Voltage and frequency fluctuations during line operation

If nothing else is stamped on the rating plate, the permissible voltage fluctuation is ±5 % and
the permissible frequency fluctuation is ±2 %, corresponding to range A in IEC/EN 60034-1.
Permissible fluctuations that go beyond these values are stamped on the rating plate.
