This manual describes the optional 6KCV300PDPBl card for connecting of inverters and converters to

Profibus-DP networks.

This manual is intendedfor design engineersandtechnicians responsible for the maintenance, commissioning

and operation of Profibus-DP systems. A basicknoyledge of Profibus-DP is assumedandmay befound in the

“Draft Standard DIN 19245Part 3” manual.

7.1. OVERVIEWOFPROFIBUS-BP

Profibus-DP is afield Busdesignedfor afast dataexchangerelating to sensors/actuators;the communication is

established between aMaster central unit (PLC or PC) andSlave units, i.e. sensors,actuators, drives, etc.

The dataexchangeis cyclic; the Master unit readsthe Slavesinput dataand writes the Slavesoutput data. The

Bus cycle time isshorter than the cycle time of the centralunit; the BaudRatesfor theGE Profibus-DP interface

card are from 9,6 kbit/s to 12kbit/s according to Profibus-DP standardpart. 3.

The total cycle time dependson the number of Slavesconnected; the 1.5-Mbit/s Baud Rate allows 8 GE drives

to be polled in 6 milliseconds. The realtionship betiveen polling (cycle) time andthe number of drives in the

network is propotional to the number of drops andthe number of words sent.

For example, at 1,5Mbit/s, the cycle time for anetwork with 24 drives is

6ms

8 drives *

drives = 18ms

i 0301

The physical support is the RS485 serial line; the mqx. number of Slavesconnectedto the Bus is 125.

There only oneProfibus-DP interface card for the AV-300 andDV-300 drives:

HARDWARE DESCRIPTION

2.2. MOUNTING

The Profibus-DP interface card is suppliedwith akit including 4 stand-offs, 4 screws, washers anda40-pole flat

cable provided with connectors.

1. Switch the drive off.

2. Fasten the Profibus-DP interface card to the drive regulation board by meansof screws and stand-offs.

As an example, pleasefind here below the drive regulation cards.

The Bus connectors have the samedirection of the regulation card terminals.

3. The flat cableis connected to the X0 connector existing on the cards.

4. The BUS terminating resistancesareconnectedor disconnectedthrough the S2 dip switch.

The last physical card in network shall havesuchresistancesconnectedin casethe connector in useshould

not contain terminating resistancesitself.

ON = connected

OFF = disconnected.

5. The Sl dip switch determines the Slaveaddress.

The addresses“0” and “1” arereservedto theMast& andcannotbeused.The switch Sl-8 is not significant

for the addressandmust always besetto OFF.The addressis only detected when the card is switched on.

If the addresshasbeenmodified, the Profibus-DP interface cardhasfirst to be switched off and then on in

order assumethe new address.

6. Connect the Bus cableto XSl or XS2 connectors.

7. Switch on the drive.

8. The LEDs +5V and +5VE ligh 1

9. The LED DEA lights up when the communication entersin the Data Exchange Phase.

2.3. POWERSUPPLY

Profibus-DP Bus

The Power supply is provided by the X0 connector, which is also usedto link data between the Profibus-DP

interface card andthe drive regulation card.

The PDP card requires 24Vdc at 350mA.

2.4. CONNECTORS

Connector PEG: It allows to connect setpoint of External Digital Supply (GNDE) to the ground (PE).

Connector PES: It allows to connect the ground (PE) at the Profibus cablesshield.

Selectionof interrupt source(INTl / INT2) from S5jumper to the 8032 microcontroller

or the Dual Port Ram interrupt input (INTR). Default position A (interrupt from the

Dual Port Ram). i

Synchronization connection of the 6KCV300PDPBl card reset signal to the drive

regulation card reset signal. Default positiont ON.

It is usedto connectthe m-OPZ signalto theINTl signal(S5A) or to the INT2 signal

(S5B). At the moment only the setting (default setting) of theinterface card asOption 1

is allowed, therefore INT_OPZ is connectedto the WI’1 signal(default position A).

It isusedto connect the OUT-OPZ signal to the OUT1 (S6.A) or OUT2 (S6.B) signal.

Default position A.

It is usedto connect the CEM-OPZ signalto the OPZl (S7.A) or OPZ2 (S7.B) signal.

The default setting of the 6KCV300PDPB 1card is Option 1, therefore the CEM-OPZ

signal is connectedto the OPZl signal. (Default position A).

Connectionof theDual PortRam BUSY signaltoRDY-EXT signal.Default position ON.

It isusedfor ibrid connection for communication. It allows to connect the capacitor C3

(1OnF2kV) in casethe connection is too long.

It isusedfor ibrid connection of theground. It allows to connect the capacitor C4 (10nF

2kV) in casethe connection is too long.

2.8. INTERFACE

The card shall beinstalled on the regulation card, sothat the Profibus-DP interface card X0 connector and the

regulation cardX0 connector arenearto eachother always keeping connectors to theProfibus-DP line directed

downwards,

For the mechanical connection pleaseusethe kit supplied with the card.

For the electrical connection pleaseuse a40-pin flat cable,also supplied.

. For the connection to the Bus pleaseuseashieldedduplex cable.
