RDCU-12C RDCU Drive Control Units

Description

RDCU-12C RDCU Drive Control Units

Before installation, check that the RDCU unit has the correct application program for
the converter hardware in question. There is a label attached to the cover of the
RDCU unit that lists “SW TYPE”, “SW CODE” and “DEVICE TYPE”.
“SW TYPE” identifies the application program that is loaded into the RDCU unit.
Some of the most common “SW TYPE” codes are AMXRxxxx (ACS800 System
Application Program), ASxRxxxx (ACS800 Standard Application Program),
AHxRxxxx (ACS800 Pump Control Application Program), and IxxRxxxx (IGBT
Supply Unit Application Program). Check that the application program corresponds
to the original order.
Check also that the “DEVICE TYPE” indicated matches that of the converter
hardware.

Removal of unit from mounting rail
• Remove the two screws (B) holding the base plate of the unit to the mounting rail.
Carefully bend the retaining clips (A) at the upper and lower edges of the cover
outwards to release the unit completely from the mounting rail.
Removal and replacement of cover
• Remove all detachable (screw-type) terminal plugs from the RDCU, and
disconnect any cables connected to the unit. Remove any optional modules.
If desired, the unit can be removed from the mounting rail as described above to
facilitate the following steps.
• With a screwdriver or similar tool, carefully release the four cover retaining clips
(C) on the right-hand side while simultaneously pulling the right-hand edge of the
cover gently away from the base plate.
• Shift the cover to the left to free its left-hand edge, then pull it to detach it
completely from the base and circuit board.
• Replace the cover in reverse order to the above (left-hand edge first). If the unit is
already mounted onto its mounting rail, align the retaining clips (A) so that they
catch on the mounting rail.

RDCU-12C+CABLES

General
The shields of the I/O cables should be grounded to the chassis of the cubicle as
close to the RDCU as possible.
Use grommets at all cable entries.
Handle fibre optic cables with care. When unplugging fibre optic cables, always grab
the connector, not the cable itself. Do not touch the ends of the fibres with bare
hands as the fibre is extremely sensitive to dirt.
The maximum long-term tensile load for the fibre optic cables included is 1 N; the
minimum short-term bend radius is 25 mm (1”).
Digital/Analogue input/output connections
See the Firmware Manual of the application program in question.
Installation of optional modules
Follow the instructions given in the user manual of the module.
Other connections
See also the wiring diagram below.
Powering the RDCU
The RDCU is powered through connector X34. The unit can be powered from the
power supply board of the inverter (or IGBT supply) module, provided that the
maximum current of 1 A is not exceeded.
The RDCU can also be powered from an external 24 V DC supply. Note also that the
current consumption of the RDCU is dependent on the optional modules attached.
(For current consumption of optional modules, see their respective user manuals.)
