1.5.3

Process data (PZD)

In the process data area PZD, control words and setpoints are transferred from the master to the slave
(frequency inverter) and in return, status words and actual values are sent from the slave to the master. The
structure of the PZD area is always the same in terms of the sequence of its elements (words), however,
dependent upon direction of data Master



Slave / Slave



Master, it is designated differently

The process data area of the reference data has the following structure:

-

STW:

C

ontrol

w

ord; length 16 Bit, order telegram

contains control bits (e.g. enable, quick stop, error acknowledgement)

-

ZSW:

S

tatus

w

ord; length 16 Bit, response telegram

contains status bits (e.g. FI running, error)

-

SW1..3:

S

etpoint

v

alues; maximum of 3 possible, 16 or 32Bit, order telegram

e.g. frequency setpoint value, position setpoint value, torque setpoint value

-

IW1..3:

A

ctual

v

alues; maximum of 3 possible, 16 or 32Bit, response telegram

e.g. actual frequency value, actual position value, actual torque value
