Drive Control Boards
There are two Drive Control Boards (DCBs) in the Low Voltage
Control Section. There is one board to control the Rectifier or Line-
Side devices (DCB-L) and one board to control the Inverter or
Machine-Side devices (DCB-M). These boards in their
unprogrammed state are the same and are interchangeable. The
DCB-M is the top board. The DCB-L is the middle board, directly
connected to the Customer Interface Board (CIB).
Figure 6.67 – DCB Board
These boards are responsible for all of the drive control processing
and store all of the parameters used for the drive control. They are
programmed at the same time that the CIB is programmed, through a
null-modem cable and the CIB (J8) port.
There is a Status LED on the DCB, labeled D1. The following Table
illustrates the states of the LED. Except where specific boards are
mentioned in the Condition description, this table is applicable to all
Circuit Boards in the Control Section.
