13.4.1
In PZD1, the master gives its control commands (control word) to the frequency inver-
ter in the output data set and receives the information on its state (status word) in the
input data set.
The control of the frequency inverter can be carried out with three different operation
modes. These are set via the data set change-over capable parameter

No.
412 Local/Remote
For operation on the Profibus, only the settings 0, 1 and 2 are relevant. The remaining
settings relate to the possibilities of control via the KP500 control unit.

Control word STW and state word ZSW have different contents depending on 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
explained later in the descriptions of the three possible operation modes.
The control and state words have been created according to DRIVECOM. In this way,
there is compatibility to PROFIDRIVE.
Note:
Data set change-over can be carried out locally on the frequency inverter via contact
inputs, or via the bus. For data set change-over via the bus, parameter

switching over between various operation modes via the data set selection
is possible. For example, it is possible to control a 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.

Function
The Start and Stop command as well as the statement
of the direction of rotation are set via digital signals.
The Start and Stop command as well as the statement
of the direction of rotation are set via the DRIVECOM
