6.2 Preset Values (Fixed Values) and Preset Reference Values
Information that you will find in
this section …
This section shows you:
what preset reference values and preset values are
the conditions under which preset reference values and preset values can be used
how to define preset reference values and preset values
and how to address preset reference values and preset values.
Description
When a preset reference value or a preset value is used a fixed value is output. The
speed is changed by switching between different preset values.
A ramp block can be set for a preset reference value. In contrast to the preset reference
value a preset value has no ramps. This is why the preset value can only be used as an
additive and factor reference value.
Up to 16 preset reference values and 8 preset values are available. Selection is binary-
coded via binary inputs or bits in a control word (via fieldbus).
When you select the preset reference values via binary inputs 16 preset reference values
and 8 preset values are available. When fieldbus is used eight preset reference values
and eight preset values can be accessed at the same time. If you don't use preset values
via fieldbus, 16 preset reference values are also accessible.
When to use preset reference
values and preset values …
Preset reference values and preset values are used when you need to switch between a
maximum of 16 reference values which do not change. An example is the 3-stage setting
of a pump.
