ABB RDCU Drive Control Units

Safety instructions

Do not attempt any work on a powered drive. After switching off the mains, always

allow the intermediate circuit capacitors 5 minutes to discharge before working on

the frequency converter, the motor or the motor cable. It is good practice to check

(with a voltage indicating instrument) that the drive is in fact discharged before

beginning work.

Avoid touching the circuit board (RMIO) inside the RDCU unit in order to minimise

the risk of damage caused by static electricity.

Do not use excessive force when detaching connectors or removing the cover of the

unit.

Identifying different types of unit

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.
