Handling of the Objects
16.3 Process Data Channel
In this chapter the handling of the PZDs
is described. The mandatory process data objects PZD1/2 are
described in chapters 16.4.1 "PZD1, Control Word / Status Word" and 16.4.5 "
/ Actual Value".
The PZD 3 … 18 objects can be used in an application specific way. Inside the inverter these objects
are represented as sources for PZD Ou
t objects (data received from Profibus master) and input
parameters for sources (data to be sent to the Profibus master).
Note: Input/output are defined from the Profibus master point of view.
16.3.1 Data Types of OUT/IN-Objects
Data Type "Boolean"
The valid values for boolean are FALSE/0x0000 and TRUE/0xFFFF.
Data Type – Boolean
Boolean
value
Data Content
hexadecimal
OUT/IN-PZDn Boolean FALSE 0x0000
OUT/IN-PZDn Boolean TRUE 0xFFFF
n = 3 … 18
Data Type "Word"
The "Word" data type can be used for percentage, current and torque variables. Current and torque
are possible in applications with field-orientation. The scalings in question are described below.
Word Data Type "Percentage"
The value range for percentage values is -300.00 to +300.00%. The values in OUT/IN-
displayed with a multiplication factor of 100.

Logical
Interpretation
OUT/IN-PZDn Word 0x8AD0 - 30000 - 300,00%
OUT/IN-PZDn Word 0x0000 0 0,00%
OUT/IN-PZDn Word 0x7530 + 30000 + 300,00%
n = 3 … 18
Word Data Type "Current"
For the current, calculation must be done in the device-internal scaling.
The scaling is:
Reference value = (Reference current [A] / Scaling current [A]) · 2
2
= 8192 (decimal) = 0x2000 (hexadecimal)
