Parameters 377
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.
Normal
Normal speed.
0
Fast

1
Very fast
Very fast speed.
2
Monitoring
