Rockwell Automation SD3000 Drive Configuration, Programming - Manual (Page 22)

l The Application Registers Updated Every Nth Scan view is used to configure the application
registers that are used for the passing of application-specific control and status data between an
AutoMax Processor and the UDC module on every Nth scan, where “N” is defined in register
2001. This register range is shared by drive A and drive B.
l The UDC Module Test I/O Register view is used to configure the register that displays the status
of the UDC module’s test switches and LED indicators. This view is also used to configure the
UDC module’s D/A meter ports.
l The Interrupt Status and Control Registers view is used to configure the registers that control a
user-defined interrupt to an AutoMax task and enable the CCLK signal on the backplane.
The Gain Data values that are used by the PMI are NOT mapped to the UDC module’s dual port
registers. The gain values are held in local tunables with reserved names which must be defined in
the UDC task for the drive (A or B). The programmer must use the pre-assigned local tunable
reserved names described in Appendix B of this manual.
Note that register values are generally in the appropriate engineering units and that the variable
names provided here are suggestions only; your variable names may be different. Duplicate
common variable names are not permitted within any one rack.
Table 3.1 lists the configuration views in the AutoMax Programming Executive, the registers to be
configured in each, and the section of this instruction manual in which the registers are discussed.
Table 3.2 lists the UDC dual port registers in numerical order.
Register Reference Conventions in this Chapter
Register numbers will be shown using the following convention: X/Y, where X is the drive A register
number and Y is the drive B register number. Note that the Interrupt Status Control registers and the
Application registers are the same for both drive A and drive B.
Most register/bit descriptions are shown in the following format:
Register Number for Drive A/B Register Name
Bit: The specific bit location, where applicable
Hex Value: The hexadecimal equivalent of the bit number
Range: The upper and lower limits of the register value, where applicable. For bit descriptions, this
field will contain N/A.
Access: The level of access by the application task (e.g., Read/Write).
UDC Error Code: A drive fault’s corresponding error code. This is reported in the log for the task in
which the error occurred.
LED: The corresponding faceplate LED, where applicable.
Description: A description of the register or bit.
