Status Parameters
11 Status Parameters
The Profibus module CM-PDPV1 has two actual value parameters which display the current status of
the module itself as well as that of the controlling software in the inverter.
Status Control
365 displays the software state of the controlling software in the inverter.
Status Fieldbus Module
366 displays the module state.
Status Control
365
Description
Wait_Process_PDP Waiting for connection to Profibus master
Wait_Process2_PDP Waiting for reconnection to Profibus master after
connection loss
Process_Active_PDP Connection to Profibus master established, Data-
Exchange with Profibus master running
Status Fieldbus Module
366 Description
WAIT_PROCESS Waiting for connection to Profibus master
PROCESS_ACTIVE Connection to Profibus master established,
Data-Exchange with Profibus master running
These parameters can show other messages that are usually not of interest. These messages are of
interest for BONFIGLIOLI VECTRON support in the case of problems and trouble shooting.
12 Error Behavior

393 Profibus Error Reaction
In the event of Profibus errors (e.g. Profibus OFF), the behavior of the inverter can be set with
Profibus Error Reaction
393.
Parameter Setting
No. Description Min. Max. Factory
Setting
393 Profibus Error Reaction 0 5 1
Operation Mode 393 Function
0 - No Reaction Inverter remains in the current state.
1 - Error Inverter enters the error state.
2 - Coast to Stop Inverter power stages are switched off and drive stops in free run.
3 - Quick-Stop The drive is decelerated with the quick stop ramps.
4 - Ramp-Stop + Error The drive is decelerated with the ramp. An error is generated after
reaching standstill.
5 - Quick-Stop + Error The drive is decelerated with the emergency stop ramp. An error is
generated after reaching standstill.
Note: The operation modes “2 - Coast to Stop” and “3 - Quick Stop” are only available when
Local/Remote
412 is set to “1 - Control via Statemachine”.
Setting PPO Type
13 Setting PPO Type
As a function of the application in question, various process peripheral objects (PPOs) with differing
lengths and contents are used for data exchange. The CM-PDPV1 offers a wide range of PPO settings.
With the help of a hardware configuration tool the user is able to construct PPO settings as needed for
his application.
Four predefined objects PPO1, PPO2, PPO3 and PPO4 and two additional objects (communication
object PKW, process data object PZD) are available for free configuration.
The required object is to be set on the DP master in the hardware configuration. There is no setting for
the required object on the side of the frequency inverter; it sets itself automatically to the projected
object.

Note: Further information on the contents of the objects is described in Chapter 16 "Handling of
the Objects".
The PKW object is used for accessing parameters (read/write) in the inverter. This object
causes additional busload because it sends its contents with every data exchange cycle,
whether it is used or not. As an alternative function without the necessity of the PKW
object, the CM-PDPV1 module supports the DP-V1 channel. This function is explained in
Chapter 16.2 "Parameter Access via the DP-V1 Channel".
Each PZD object has two words of input/output data. The handling of this object is
explained in chapter 16.3.1 "Data Types of OUT/IN-Objects".
