BONFIGLIOLI Vectron ACTIVE CUBE - Process Data Channel (PZD)

8.3 Process data channel
This chapter describes how to handle the PZD objects. For a description of the re-
quired process data objects PZD1/2, refer to Chapters 11.1 “Control via con-
tacts/remote contacts”, 11.2 “Control via state machine” and 11.3.3 “
Reference val-
ue/actual value”.
Objects PZD 3 … 12 can be used application-specifically. In the frequency inverter,
these objects are represented as sources for PZD Out objects (data received from
PROFINET controller) and as input parameters for sources (data to be sent to the
master).
Inputs and outputs are as seen from the point of view of the PROFINET controller.
8.3.1 Data types of OUT/IN objects
Data type “Boolean”
Permissible values of “Boolean” are FALSE/0x0000 and TRUE/0xFFFF.

Data type “Word”
The “Word” data type can be used for percentage, current and torque variables. Cur-
rent and torque variables are possible in applications with field-oriented control. The
standardization is as described below.
Word data type “Percentage”
The range for percentage values is -300.00% … +300.00%. The values in OUT/IN-
PZDn are shown with a factor of 100.

Word data type “Current”
A device-internal standardization conversion is performed for the current.
The standardization is as follows:
Reference value = (Reference current [A] / Standard current [A]) · 2
