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

1000.

Sug. Var. Name: F_CMD!

Units: 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.
