4.3.2.2 Immunity Requirements

The immunity requirements for the servo drives and SAB
depend on the environment where they are installed. The
requirements for the industrial environment are higher
than the requirements for the home and office
environment. All servo drives and the SABs comply with
the requirements for the industrial environment and
consequently also comply with the lower requirements for
home and office environment with a large safety margin.
®
The VLT Integrated Servo Drive ISD 510 System complies
with the immunity requirements for 2
according to EN 61800-3.
To document immunity against electrical interference, the
following immunity tests have been made in accordance
with following basic standards:
•
EN 61000-4-2 (IEC 61000-4-2): Electrostatic
discharges (ESD): Simulation of electrostatic
discharges from human beings.
•
EN 61000-4-3 (IEC 61000-4-3): Incoming electro-
magnetic field radiation, amplitude modulated
simulation of the effects of radar and radio
communication equipment as well as mobile
communications equipment.

EN 61000-4-4 (IEC 61000-4-4): Burst transients:
Simulation of interference brought about by
switching a contactor, relay, or similar devices.
•
EN 61000-4-5 (IEC 61000-4-5): Surge transients:
Simulation of transients brought about for
example by lightning that strikes near instal-
lations.
•
EN 61000-4-6 (IEC 61000-4-6): RF Common mode:
Simulation of the effect from radio-transmission
equipment joined by connection cables.
