XENDAT,
EXTENDED REGISTER GROUPS
The speed sent to the regulator and gearbox is limited
to ±32767000. If this speed does not allow a sufficiently
high rpm, the resolution of the sensor has to be
decreased. (See XENDAT.PosShift).
XENDAT.SerABSPos 13 Not A R 0
This is the serial absolute position as received from the
sensor, the position wraps at the capacity of the sensor.
The value is only updated if bit 0 in XENDAT.Mode is
set.
Note A. Sensor dependent, max 32bit.
XENDAT.SerPos 14 ±31 bit R 0
This is the serial extended position from the sensor.
The position wraps at the DMC
XENDAT. SerWrapCnt
XENDAT.Mode is
2 32 bit position capacity.
The member can control the
difference between this position and the absolute
position.
The value is only updated if bit 0 in
set.
XENDAT.SerErrors 15 ±31 bit RW
Error counter for transmission errors from the endat
sensor.
The following errors are counted:
Alarm from endat.
CRC error on received frame.
5 Volt supply error.
XENDAT.IncErrors 16 ±31 bit RW 0
i
Error counter for detected errors in the UP/DOWN
counter. This quadrature counter is used to count the
whole sine/cosine periods of the analog ENDAT signal.
When there is a situation where both input signal
change state at the same time, the discriminator in the
encoder cannot determine if this should be an UP or
DOWN count. In this case the I errors counter is
incremented.
Since the same hardware counter is used in the
IENC group, this error counter is also common to
both groups.
XENDAT.SerIncOffs 17 ±31 bit R 0
When combined serial and analog (incremental) mode
is used, this value holds the difference between the
incremental and the absolute position from the sensor. If
there are no errors, this value will be constant, once the
system is started.
