EMC and Machine Directive 49
8. EMC and Machine Directive
8.1 EMC standards
The variable speed 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 environ-
ment, is intended to be installed and commissioned
only by experienced person with the necessary skills in
installing and/or commissioning variable speed drives
including their EMC aspects.
8.2 Stop categories and
emergency stop
The following information is important if emergency
stop circuits are used or needed in the installation
where a variable speed drive is used. EN 60204-1
defines 3 stop categories:
Category 0: Uncontrolled STOP:
Stopping by switching off the supply voltage. A mechan-
ical stop must be activated. This STOP may not be
implemented with the help of a variable speed 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 variable speed 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 variable
speed 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 stop according EN954-1
Category 3 can be achieved. See chapter 13.8 page 159
