Division ratio fieldbus task
The set value generator for the cyclical set values (=
Z
1.10
–
fieldbus task cycle) is exe-
cuted in every fieldbus cycle (
Z
131.18
–
). A quicker cycle than the fieldbus cycle can be
set by the division ratio.
Division ratio =
1: Cyclical set value generator is activated once per fieldbus cycle
2: Cyclical set value generator is activated twice per fieldbus cycle
4: Cyclical set value generator is activated four times per fieldbus cycle
etc.
The resulting
Z
1.10
–
fieldbus task cycle may not fall below the
Z
1.8
–
RTO cycle time
and should at least be 250 µs.
Example:

Z
131.18
–
Fieldbus cycle time = 2 ms; division ratio = 8;

Z
1.8
–
RT0 cycle time = 250 µs

2 ms / 8 = 250 µs.
A call up ratio greater than 8 would no longer be admissible anymore.
The following operating modes are considered as cyclical set values:
m Z
109.1
–
= -4; position control with a synchronous set value setting;
Z
136.3
–
target
position and
Z
136.5
–
target angle
m Z
109.1
–
= -12; coupled operation;
Z
122.3
–
master axis position revolutions and
Z
122.4
–
master axis position angle

Configuration profile 1
This parameter configures the used drive profile in the fieldbus slave.
The definition of the parameter depends on the fieldbus slave type. The description is to
be found in the corresponding technical documentation.
The controller must be rebooted after changing a parameter.
For other specific settings corresponding to the fieldbus, see parameter

settings.
NOTE!
A parameter change is permitted at a inhibited state and in the fieldbus state INIT
