Configuring the UDC Module’s Registers
3-3
•
Register Name: Functional name of the register (e.g., Torque Reference Register).
•
Register A/B 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 module faceplate LED, where applicable (e.g. EXT FL on
the PMI Processor module).
