-
Selects the communication time levels.
In general, lower time levels of read/write services reduce
CPU load. The table below shows the time levels of the
read/write services for cyclic high and cyclic low data with
each parameter setting.
* Cyclic high data consists of fieldbus Status word, Act1 and
Act2.
** Cyclic low data consists of the parameter data mapped to
parameter groups
and
,
and acyclic data.
Control word, Ref1 and Ref2 are handled as interrupts
generated on receipt of cyclic high messages.
Note:
This parameter cannot be changed while the drive is
running.
