2 Description of RD51
2.1 The RD 500 Device Series
RD 500 is a state-of-the-art, universal three-phase drive system for
various synchronous and induction motors. The modular hardware and
software design allows the drive system to be flexibly adapted to the
particular drive application.
The system includes various AC drive converters (with/without braking
chopper, line contactor etc.), inverters for DC supply as well as rectifier
and supply modules which are capable of regenerative feedback into the
line supply. The modules can be individually purchased, or as a system,
completely wired in the cabinet.
The power sections are designed for cooling at the rear. This means that
forced cooling, also outside the cabinet, can be implemented with an
associated higher degree of protection (where the heat sink extends
outside the cabinet or using a conductive plate). In addition, versions are
available with liquid cooling with either integrated or external heat
exchangers.
Handling
Special significance was placed on simple handling, for instance,
automatic motor adaptation with parameter identification.
The drive system is commissioned with prompts using the operator panel
with graphical display or with the highest level of user friendliness using a
PC with the high-performance RDwin software package.
Electromagnetic Compatibility
In order to reduce the harmonics fed back into the line supply, radio
interference suppression filters and line reactor are integrated into the AC
drive converters, size classes C - E. RD 500 is in full compliance with the
EMC Directives regarding noise immunity and noise emission according
to the EMC Product Standard for electric drives EN 61800-3, EN 55011
Class A (IEC 61800-3). RD 500 is immune to noise in conformance with
EN 50082-2.
