3-46 SA3100 Drive Configuration and Programming
Iq Feedback Normalized Register (Vector) 213/1213
In Vector mode, register 213/1213 functions as Iq Feedback
Normalized register. This register contains the Iq (torque producing)
component of the current feedback. The data is normalized so that
+/- 4095 counts corresponds to the torque reference (TRQ_REF%). Sug. Var. Name: IQ_FBN%
Units: Counts
Range: +/- 4095
Access: Read only
Output Frequency Register (V/Hz) 212/1212 and 213/1213
In Volts per Hertz mode, registers 212/1212 and 213/1213 function
as the Output Frequency register. This double precision register
contains the output frequency value of the drive. Register 212/1212
holds the high word. Register 213/1213 holds the low word. The
value is scaled in Hz

User Analog Input Register 214/1214
The User Analog Input register contains the measured user analog
input value from the Resolver Feedback connector on the Resolver &
Drive I/O board. Sug. Var. Name: ANA_IN%
Units: Counts (Volts)
Range: -2048 to +2047
(-10V to +10V)
Access: Read only
Resolver Scan Position Register 215/1215
The Resolver Scan Position register contains the electrical position of
the resolver at the beginning of the UDC task scan. This register is
reset to zero at power-up. Sug. V ar. Name: RES_SCN_POS%
Units:
Counts
Range: -32768 to +32767
Access: Read only
Resolver Strobe Position Register 216/1216
The Resolver Strobe Position register contains the electrical position
of the resolver at the time a strobe signal is detected. Sug. Var. Name: RES_STR_POS%
Units:
Counts
Range: -32768 to +32767
Access: Read only
Current Feedback Normalized Register (V/Hz) 216/1216
In Volts per Hertz mode, register 216/1216 functions as the Current
Feedback Normalized register. This register contains the measured
RMS motor current. The data is normalized so that +/- 4095 counts is
equal to the rated motor current times the motor overload ratio. Sug. Var. Name: I_FBN%
Units: Counts
Range: +/- 4095
Access: Read only
This register is used as the I_FDBK parameter in the THERMAL OVERLOAD control block used in DPS
drives to monitor the motor for thermal overload.
Note that the regulator uses a value of 150% overload for this function. If another value of overload ratio is
desired, it must be communicated to the regulator via the dual port register 711/1711.
