RD2, Resolver/Digital converter #2<br />
EXTENDED REGISTER GROUPS<br />
tuned to perform accurately at up to 30000 rpm for a 2-pole<br />
(single speed) resolver.<br />
Note. The content <strong>of</strong> the SysIo.PWM0 register<br />
affects both<br />
resolver #1 and #2; since both resolvers are driven from the<br />
same excitation circuit.<br />
RD2.SHAdj 4 -150..150 RW<br />
Sample/Hold phase adjustment (the time <strong>of</strong>fset for sample/hold<br />
signal is in microseconds.) This value is used to adjust the phase<br />
<strong>of</strong> the sample/hold signal so that the SIN and COS signals are<br />
sampled at their maximum, and thereby the RD2.Ampl reaches<br />
its maximum value. At this adjustment, the RD2 is tuned to<br />
perform accurately at up to 30000 rpm for a 2-pole (singlespeed)<br />
resolver. If the RD2.Ampl maximum exceeds<br />
16000, and<br />
the corresponding resolver is only used at low speeds (maximum<br />
500-1000 rpm for a 2-pole resolver), this value may be detuned<br />
to decrease the RD2.Ampl below 16000.<br />
RD2.FiltSpeed 5 -2 31 ..2 31 -1 R<br />
The filtered result from RD2.Speed when RD2.Mode is 5 or 7. It<br />
is calculated as the mean value over the last 4 servo cycle<br />
samples <strong>of</strong> RD2.Speed.<br />
RD2.RPos 6 -2 31 ..2 31 -1 R<br />
Resulting position when the value in RD2.PosOffs is applied.<br />
RD2.SinOffs 7 -16384..16383 RW<br />
In High-speed mode, these values are the RD-electronics <strong>of</strong>fset<br />
calibration values. The <strong>of</strong>fset values are subtracted from the A/D<br />
input values to give SysIo.RD2Sin and SysIo.RD2Cos.<br />
RD2.CosOffs 8 -16384..16383 RW<br />
In High-speed mode, these values are the RD-electronics <strong>of</strong>fset<br />
calibration values. The <strong>of</strong>fset values are subtracted from the A/D<br />
input values to give SysIo.RD2Sin and SysIo.RD2Cos.<br />
RD2.AmplAdj 9 -1..1 NIU<br />
NIU.<br />
RD2.SinGain 10 -4096..+4096<br />
Sine/cosine gain compensation. To be used in high-resolution<br />
mode.<br />
Adjustment: ±12.5 %<br />
-4096 -12.5 % less<br />
0 unity (100%)<br />
4096 12.5 % larger<br />
This member is used to compensate gain errors between the<br />
sine and the cosine amplifier. The value can be found by rotating<br />
the motor while searching the SysIo.RD1Sin maximum and<br />
SysIo.RD1Cos maximum (preferely in a PL program), then<br />
calculate as;<br />
