Technical data

● Continuous operation (green area in the figure)

Operating state that is permissible for the complete operating time.

● Short-time duty (yellow area in the figure)

Operating state that is permissible for less than 2% of the total operating time.

● Sporadic short-time duty (red area in the figure)

Operating state that is permissible for less than 1% of the total operating time.

9.5 Electromagnetic compatibility of the converter

EMC (electromagnetic compatibility) means that the devices function satisfactorily

without interfering with other devices and without being disrupted by other devices.

EMC applies when the emitted interference (emission level) and the interference

immunity are matched with each other.

The product standard IEC/EN 61800-3 describes the EMC requirements placed on

"Variable- speed drive systems".

A variable-speed drive system (or Power Drive System PDS) consists of the converter

as well as the associated electric motors and encoders including the connecting

cables.

The driven machine is not part of the drive system.

Note

PDS as component of machines or systems

When you install PDS into machines or systems, additional measures may be

required so that the product standards of these machines or systems is complied

with. The machine or system builder is responsible for taking these measures.

Overview of environments and categories

Environments

IEC/EN 61800-3 makes a distinction between the "first environment" and

"second environment" - and defines different requirements for these

environments.

● First environment

Residential buildings or locations at which the PDS is directly connected to a

public low- voltage supply without intermediate transformer.

● Second environment

An environment that includes all other establishments which are not

connected directly to a public low-voltage line supply.
