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%).

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

The User Analog Input register contains the measured user analog
input value from the Resolver Feedback connector on the Resolver &
Drive I/O board.

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.

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.

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.
