3-2 SA500 Drive Configuration and Programming
• The Feedback Registers view is used to configure the feedback registers that
display the current status of the drive. These registers are written to by the PMI.
• The Application Registers Updated Every 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 scan.
This register range is shared by drive A and drive B.
• 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.
• 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.
• 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 non-volatile 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.
3.1 Register and Bit Reference Conventions
Used in this Manual
Register numbers are shown using the convention A/B, where A is the drive A register
number and B 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.
Register descriptions are shown in the following format:
