Configuring the UDC Module’s Registers 3-23
I/O Control Register (Continued) 101/1101
External Fault LED Bit 2
The External Fault LED command bit is set
by the application task to turn on the EXT
FLT LED on the PMI Regulator. Hex Value: 0004H
Sug. Var. Name: EXT_LED@
Access: Read/Write
UDC Error Code: N/A
LED: EXT FLT
Auxiliary Output Bit 4
The Auxiliary Output command bit is set to
turn on the auxiliary output on the Resolver
& Drive I/O board. Hex Value: 0010H
Sug. Var. Name: AUX_OUT@
Access: Read/Write
UDC Error Code: N/A
LED: AUX OUT
Enable Resolver Calibration Test Bit 6
The Enable Resolver Calibration Test bit is
set to begin the test that determines the
resolver’s balance value. This value will be
stored in the pre-defined local tunable
RES_BAL%. Hex Value: 0040H
Sug. Var. Name: RES_CAL@
Access: Read/Write
UDC Error Code: N/A
LED: N/A
This bit is edge sensitive. The test will turn off if the bit is reset. Refer to register
201/1201, bits 6 and 7, for information on the calibration test complete bits. Refer to
the PMI Regulator instruction manual (S-3057) for additional resolver calibration
information.
Enable External Strobe Bit 8
The Enable External Strobe bit is set to
enable the external strobe on the resolver to
capture the position of the resolver when the
rising edge of the external strobe is
detected. As long as this bit is set, the
external strobe is enabled. Hex Value: 0100H
Sug. Var. Name: STR_ENA@
Access: Read/Write
UDC Error Code: N/A
LED: N/A
If this bit is set in conjunction with bit 9, the resolver position is captured on both the
rising and falling edges of the input signal. See register 201/1201, bits 8 and 9, for
additional information. The resolver position data is placed in the Resolver Strobe
Position register (register 216/1216).
