When
16.11
is set at 0 (default), and the
SIN
-
COS
encoder shaft position is
being read from parameters
16.03
,
16.04
and
16.05
by a large option
module (eg. UD70) or via serial communications, the values of these
parameters are free to change during the read process. This can result in
large position-errors being read.
To ensure that the position information from all three parameters is
consistent when reading the values, set
16.11
at 1 to hold the three
parameters at the last complete set of values. When the read process is
completed, return
16.11
at 0 to allow the parameter values to continue to
be updated.
