Process Data Channel Pzd1/Pzd2; Pzd1, Control Word / State Word - BONFIGLIOLI ACTIVE Manual

10.2
In this chapter, the basic functions of the PZD1 and PZD2, which are identical for all
the objects PPO1 to PPO4, are described.
10.2.1
In PZD1, the master gives its control commands (control word) to the frequency in-
verter in the output data set and gets the information about its state (state word) in
the input data set.
The control of the frequency inverter can be done with three differing operation
modes. They are set via the data set change-over capable parameter
412.
412 Local/Remote
For operation on the Profibus, only the settings 0, 1 and 2 are relevant. The further
settings relate to the possibilities of control via the KP500 control unit.
Control word STW and state word ZSW have differing contents as a function of the
operation mode. In each case, all or only some of the bits in the control word are
relevant and also only certain feedbacks are possible via the status word. These are
then explained in the descriptions of the three possible operation modes.
Control and state word have been created according to DRIVECOM. In this way, there
is compatibility to PROFIDRIVE.
Note:
The data set change-over can be done locally at the frequency inverter via contact
inputs or via the bus. For the data set change-over via the bus, the parameter

switching over between various operation modes via the data set selection
is possible. For example, it is possible to control an frequency inverter via
the bus and to activate a local emergency operation if the bus master
breaks down. This switch-over is also visible via the state word (Bit Re-
mote).
414 is used.

The Start and Stop command as well as the statement of
the direction of rotation are via the DRIVECOM State
machine of the communication interface.
The Start and Stop command as well as the statement of
the direction of rotation are via logic signals by the com-
munication protocol.
