Configuring the UDC Module’s Registers 3-3
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:
• Register Name: Functional name of the register (e.g., Torque Reference Register).
• Register Numbers: Memory addresses of registers A and B.
• Sug. Var. Name: Suggested variable name for the register (e.g., TRQ_REF%).
• Units: Scaling unit applied to the value stored in the register (e.g., counts,
amps * 10, etc.).
• Range: The upper and lower limits of the value, where applicable (e.g. -4095 to
+4095).
• Access: The level of access by the application task (Read, Write, or Read/Write).
Throughout this manual, bit descriptions are shown in the following format:
• Bit Name: Functional name of the bit (e.g., DC Bus Over Voltage Fault).
• Bit Number: The specific bit location within the register (e.g., Bit 0).
• Hex Value: The position within the 16 bit register (e.g., Bit Number 4 = 0010H)
• Sug. Var. Name: Suggested variable name for this bit (e.g., FLT_OV@ ).
• Access: The level of access by the application task (e.g., Read/Write).
• UDC Error Code: A drive fault’s corresponding error code (e.g. 1018). This is
reported in the log for the task in which the error occurred.
• LED: The corresponding status LED, where applicable (e.g., EXT FLT on the PMI
Regulator).
