Appendix A:- Test Configurations for EMC-related CE-Compliance
The T200 Series Motor Controllers are system components which must be installed in a correct manner to ensure that all
electromagnetic compatibility (EMC) requirements are met. The requirements of European Union (EU) EMC Directive:
89/336/EEC, as amended, must be met by all equipment, systems and installations into which the T200 Series Motor
Controllers are installed.
The T200 Series Motor Controllers have been tested for compliance with the EU EMC Directive in so far as they can be
regarded as single functional units. The T200 Series Motor Controllers have been tested in typical configurations and it
has been found that these configurations meet the essential requirements of the EU EMC Directive.
Test Configuration 1: EMC Emissions: 3 Phase Power application.
The configuration consisted of a Model T200-310 Drive and two Model T200-300 Drives. The Drives were connected to
Motors via 10m Motor Power and Motor Resolver shielded cables, terminated to chassis earth at each end. One T200-
300 had a motor brake option installed with cable connection to the MOTOR BRAKE port
All drives were driven by an external CANBUS (CAN) test computer connected via a 30m shielded cable to the T200-
310 Drive and daisy chained via the CAN IN and CAN OUT ports to the two T200-300 Drives. There was a Steward
type 28A2024-0A0 ferrite installed through 1.5urns on the 30m shielded cable at the T200-310 port.
There were 3m shielded cables terminated in characteristic impedances connected to the following ports on all Drives:
Encoder port, ESM Out port, Serial port, Axis Signals port. There was an in-line FairRite Type 0443164151 ferrite
installed at each end of the Axis Signal port cables for each Drive. There was a 3m shielded cable terminated in
characteristic impedances connected to the Power Ready port on the T200-310 Drive.
Input power was supplied via a 3 phase 400:230 V a.c. step down isolation transformer connected by armoured cable to
the AC LINE IN port on the T200-310 Drive. The DC BUS voltage was daisy chained from the T200-310 Drive to the
two T200-300 Drives.
An optional 24Vd.c. control backup supply was connected to the 24Vd.c. control backup port of the T200-310 and
daisy-chained to the two T200-300's. A Steward 28A2024-0A0 ferrite was installed through 2.5turns on the external
24Vd.c supply cable at the T200-310 port. This external 24Vd.c. power supply was supplied from a connection to one
of the secondary phases of the 400:230Va.c. step down transformer.
All Drives were mounted onto an earthed metal panel mounted in turn onto an earthed equipment chassis frame. The
bare metal rear panel of each Drive enclosure was fixed in direct contact with the earthed metal panel on the equipment
chassis.
Output cables were grouped and routed along the chassis of the equipment frame in a manner similar to cable routing on
machinery. The motor power and motor resolver cables were grouped together and installed in a fixed routing to the
motors. The output port cables, motor power and resolver cables, and power input cables had segregated routings.
Test Configuration 2: EMC Emissions: 3 Phase Power application.
The configuration consisted of a Model T200-410 Drive and Model T200-400 Drive. The T200-400 Drive had a T200
Personality Module option ( Moog p/n C09951) installed. The Drives were connected to Motors via 10m Motor Power
and Motor Resolver shielded cables, terminated to chassis earth at each end.
There were 3m shielded cables terminated in characteristic impedances connected to the following ports on all Drives:
Encoder port, ESM Out port, Serial port, Axis Signals port. There was an in-line FairRite Type 0443164151 ferrite
installed at each end of the Axis Signal port cables for each Drive.
