6. EMC and standards
6.1 EMC standards
The AC drive complies with the following standards:
EN(IEC)61800-3:2004 Adjustable speed electronic power
drive systems, part 3, EMC product standards:
Standard: category C3, for systems of rated supply
voltage< 1000 VAC, intended for use in the second
environment.
Optional: Category C2 for systems of rated supply
voltage <1.000 V, which is neither a plug in device nor a
movable device and, when used in the first environment, is
intended to be installed and commissioned only by
experienced person with the necessary skills in installing
and/or commissioning AC drives including their EMC
aspects.
6.2 Stop categories and
emergency stop
The following information is important if emergency stop
circuits are used or needed in the installation where a AC
drive is used. EN 60204-1 defines 3 stop categories:
Category 0: Uncontrolled STOP:
Stopping by switching off the supply voltage. A mechanical
stop must be activated. This STOP may not be
implemented with the help of a AC drive or its input/output
signals.
Category 1: Controlled STOP:
Stopping until the motor has come to rest, after which the
mains supply is switched off. This STOP may not be
implemented with the help of a AC drive or its input/output
signals.
Category 2: Controlled STOP:
Stopping while the supply voltage is still present. This
STOP can be implemented with each of the AC drives
STOP command.
WARNING!
EN 60204-1 specifies that every machine
must be provided with a category 0 stop.
If the application prevents this from being
implemented, this must be explicitly stated.
Furthermore, every machine must be provided with
an Emergency Stop function. This emergency stop
must ensure that the voltage at the machine
contacts, which could be dangerous, is removed as
quickly as possible, without resulting in any other
danger. In such an Emergency Stop situation, a
category 0 or 1 stop may be used. The choice will be
decided on the basis of the possible risks to the
machine.
NOTE: With option Safe Stop, a “Safe Torque Off
(STO)” stop according EN-IEC 62061:2005 SIL 3 &
EN-ISO 13849-1:2006, can be achieved.
