2.12 EMC compliance (Elevator standards)
This section provides specific information for the E300 Elevator drives when used in lifts, elevators and escalators which are required to comply with
the harmonized European EMC standards EN 12015:2014 (emission) and EN12016:2013 (immunity). The information given here includes the
requirements of the revised versions. For full details refer to the EMC data sheet, which can be obtained from the supplier of the drive.
2.12.1 Emission - EN 12015:2014
The standard sets limits in the following categories:
1. Radiated emission from the enclosure
This covers the frequency range 30 MHz to 1000 MHz.
The limits are the same as for the generic standard EN 61000-6-4 and are unchanged from the 1998 version.
2. Conducted emission from the AC mains port(s)
This covers the frequency range 0.15 MHz to 30 MHz.
The limits are the same as for the generic standard EN 61000-6-4 and are unchanged from the 1998 version.
3. Conducted emission from the power port(s) (motor port etc).
This covers the frequency range 0.15 MHz to 30 MHz.
These are new limits, which apply unless the motor cable length does not exceed 2 m or it is screened.
4. Impulse noise
This is a special requirement for impulsive conducted emission.
The limits are the same as for the 1998 version.
5. Voltage fluctuations
This covers fluctuations, which are variations in the supply voltage which result in lighting flicker.
These are new limits. They are based on the standard EN 61000-3-11.
6. Mains current harmonics
This covers harmonics up to order 40.
These are new limits. They are based on standard IEC 61000-3-4.
Conformity of the Control Techniques drive products with EN 12015
The drives conform to the standard for Power Drives Systems, EN 61800-3, and the generic standard for industrial environments EN 61000-6-4.
In many respects this also covers the requirements of EN 12015.
Mains conducted emission
Generally the standard optional external filter must be used.
The motor cable length is set by the filter capability, on the assumption that the highest available switching frequency is in use. If longer lengths are
required this can usually be achieved by reducing the switching frequency, see the appropriate EMC data sheet for further information.
Where the lift system has a rated input current exceeding 100 A, and a dedicated supply transformer, higher emission levels are permitted and then
only the built-in filter is required.
Please note that the standard test method requires the use of a mains supply cable 1 m long, this being the cable which connects the system under
test to the LISN (line impedance stabilization network). This requirement might be inconvenient and appear to be unrealistic in some cases. However
it is important to adhere to this recommendation to ensure a valid and comparable test result.
Output conducted emission
The cable must be screened and the screen must be correctly bonded in accordance with the EMC (Electromagnetic compatibility) section of this
Installation and System Design Guide or the EMC data sheet for the product, unless the motor cable length is less than or equal to 2 m in length.
Impulse noise
The drive does not generate impulse noise. Care is required to ensure that associated power contactors do not generate impulse noise.
Voltage fluctuations
The drive does not in itself cause significant voltage fluctuations or flicker. The control system must be designed so as not to cause rapid changes in
motor power which could result in flicker. Generally the requirements for passenger comfort ensure that this is the case.
