21 1/121 1 Field Minor Loop Feedback Register
Hex Value: N/A
Sug. Var. Name:
FML_FB%
Range: -32768
to
+32767
Access:
Read Only
UDC Error Code:
N/A
LED:
N/A
Description:
The Field Minor Loop Feedback register displays the measured field current (DC Amps)
in counts. A value of 4095 is equal to 100% of the Motor Field Hot Amps value in the parameter entry
screen.
212/1 212 Field Current Feedback Register
Hex Value:
N/A
Sug. Var. Name:
FLD-IFB% (amps x 100)
Range: -32768
to +32767
Access:
Read Only
UDC Error Code:
N/A
LED:
N/A
Description:
The Field Amps Feedback register displays the measured field current. The displayed
value is equal to the number of amps times 100. For example, 10.00 amps of field current would be
displayed as 1000. The current is measured to within a tenth of an amp.
213/1 213 Field Voltage Feed back Register
Hex Value:
N/A
Sug. Var. Name:
FLD_VFB% (DC Volts)
Range: -32768
to +32767
Access:
Read Only
UDC Error Code:
N/A
LED:
N/A
Description:
The Field Voltage Feedback register displays the field voltage feedback value. A value
of 1 is equal to 1 volt. This voltage is calculated based on the AC line and field firing angle.
214/1 214 User Analog input Register
Hex Value:

Access:
Read Only
UDC Error Code:
N/A
LED:
N/A
Description:
The Resolver Scan Position register displays the electrical position of the resolver (if
used) at the beginning of the UDC task scan. This register is reset to zero at power-up.
216/1 216 Resolver Strobe Position Register
Hex Value:
N/A
Sug. Var. Name:
RES_STR_POS%
Range: -32768
to 32767 corresponding to the resolver’s position
Access:
Read Only
UDC Error Code:
N/A
LED:
N/A
Description:
The Resolver Strobe Position register displays the electrical position of the resolver at
the time a strobe signal is detected.
