Position <strong>of</strong>fset between<br />
XENDAT.RPos.<br />
XENDAT.Pos and<br />
XENDAT.SerWrapCnt 20 ±31 bit RW 0<br />
Position <strong>of</strong>fset between<br />
XENDAT.SerPos.<br />
XENDAT.SerABSPos and<br />
XENDAT,<br />
This value can only be set to multiples <strong>of</strong> the ENDAT<br />
sensor capacity. Typical use is to set the home position<br />
with aid <strong>of</strong> external sensors if the ENDAT absolute<br />
range is not large enough.<br />
XENDAT.SinOffs 21 0..16384 RW 8192<br />
Offset calibration for ENDAT sine-signal.<br />
XENDAT.CosOffs 22 0..16384 RW 8192<br />
Offset calibration for endat cosine-signal.<br />
XENDAT.PosShift 23 0..11 RW 0<br />
i<br />
In ENDAT analog mode, or combined mode, this value<br />
is the number <strong>of</strong> bits from the evaluation <strong>of</strong> the analog<br />
sine and cosine signals that is added to the serial<br />
position data.<br />
This parameter does not affect the values that are<br />
used for commutation <strong>of</strong> the motor.<br />
The motor is commutated on the standard (nonextended)<br />
value from the ENDAT sensor. Motor.Ppr<br />
shall be set to the resolution the sensor has when<br />
XENDAT.PosShift is set to zero, and it is not to be<br />
changed when the XENDAT.PosShift is changed.<br />
Since this parameter changes the magnitude <strong>of</strong> speed<br />
and position sent into the regulator for a given<br />
mechanical movement, the regulator gain settings as<br />
well as motion pr<strong>of</strong>iles etc will have to be changed if the<br />
resolution <strong>of</strong> the sensor is changed.<br />
XENDAT.SerPosAge 24 0..32767 R<br />
Age(in milliseconds), <strong>of</strong> last serial position value from<br />
the Endta sensor (i<br />
XENDAT.SerTimeOut 25 0..32767 RW<br />
Timeout (in milliseconds), before a position error<br />
interurpt is set pending. (See<br />
Xendat.mode)<br />
