5.2.1Network topology

The following examples show two simple RS485 networks.

Every segment of the network must be terminated at both ends. The bus terminators of the PROFIBUS are marked with a "Z" in the below examples.

With a RS485 network of only one segment, the PROFIBUS master (M) with the integrated bus terminating resistor starts the bus. The bus must be terminated by means of a bus terminating resistor at the last PROFIBUS station (S).

Installation

Electrical installation

If no repeater is to be used at the end of the segment, the bus must be terminated by means of a bus terminating resistor at the last station (S). The bus termination is supplied by this station.

An external supply of the communication unit provides for a supply of the bus termination independent of the supply of the controller.

Note!

The bus terminator must always be supplied. Otherwise, the bus can get unstable.

Tip!

Repeaters do not have a station address. When calculating the maximum number of stations, they reduce the number of stations by 1 on each side of the segment.

Repeaters can be used to build up line and tree topologies. The maximum total bus system expansion depends on ...

•the baud rate used;

•the number of repeaters used.

5.2.2Bus termination

The PROFIBUS must be terminated by means of a bus terminating resistor at the first and last physical station.

In the case of the communication unit, the bus terminating resistor can only be installed externally at the M12 connector. This has the advantage that an installed resistor is visible when the device is closed.

Note!

•The PROFIBUS connections (input and output) must be installed in an enclosed manner. Please use either a connection cable, an enclosed bus terminator connector (M12 male, 4-pin, B-coded) or a cap.

•Connection cables or bus terminator connectors are offered by several cable manufacturers (e.g. Lapp or Turck).

•If you want to disconnect individual bus stations, ensure that the bus terminators at the cable ends remain active. Otherwise, the bus may become unstable.

•Please observe that the bus termination is not active any longer if ...

–the bus terminator connector has been disconnected;

–the mains supply of the drive unit and the external 24V supply of the communication unit have been switched off at the same time.

5.2.3Bus cable specification

Note!

Only use cables that correspond to the given specifications of the PROFIBUS user organisation.

Area	Values
Cable resistance	135 ... 165 Ω/km, (f = 3 ... 20 MHz)
Capacitance per unit length	≤ 30 nF/km
Loop resistance	< 110 Ω/km
Core diameter	> 0.64 mm
Core cross-section	> 0.34 mm2
Cores	Twisted in pairs, insulated and shielded

Bus cable length

The bus cable length depends on the baud rate used:

Baud rate	Length
9.6 ... 93.75 kbps	1200 m
187.5 kbps	1000 m
500 kbps	400 m
1500 kbps	200 m
3000 ... 12000 kbps	100 m

Note!

The baud rate depending of the data volume, cycle time and number of stations should only be selected as high as required for the application.

Tip!

For high baud rates, we recommend taking the use of optical fibres into consideration.

Advantages of optical fibres:

•External electromagnetic interferences have no effect on the transmission path.

•Bus lengths of several kilometres are also possible with higher baud rates. The bus length is ...

–independent of the baud rate;

–dependent on the optical fibre used.

5.2.5External voltage supply

By means of the external voltage supply, PROFIBUS communication for commissioning can be established, and the data of the digital and analog inputs can be queried.

Furthermore the external voltage supply serves to maintain PROFIBUS communication if the main supply fails.

The digital inputs RFR, DI1 ... DI5 and the analog input can continue to be evaluated.

The external voltage supply is done via the terminals 24E and GND of the terminal strip X3.

Permissible voltage (DC) / max. current:

–U = 24 V DC (20 V - 0 % ... 29 V + 0 %)

–Imax = 400 mA

Access to parameters of a device that is disconnected from the mains is not possible.

Commissioning

Before initial switch-on

6 Commissioning

During commissioning, plant-specific data such as motor parameters, operating parameters, responses, and parameters for fieldbus communication are defined for the controller. Lenze devices use codes for this purpose.

The codes of the controller and for communication are saved to the memory module in a non-volatile data set.

In addition, there are codes for diagnosing and monitoring the stations. Parameter reference ( 81)

6.1Before initial switch-on

Stop!

Before switching on the controller for the first time, check ...

•the entire wiring for completeness, short circuit and earth fault.

•whether the bus system is terminated through a bus terminating resistor at the first and last physical bus station.

Configuring the host (master)

6.2Configuring the host (master)

For communication with the controller, you have to configure the host (master) first.

Configuration for the host (master) and the DP-V0 parameter data channel

For the configuration of the PROFIBUS, the PROFIBUS device description file of the Inverter Drive 8400 motec must be read into the master.

The device description file is available on Lenze's website in the "Services & Downloads" area at:

www.Lenze.com

The following language variants of the device description file can be used:

LENZE84D.GSD (source file, English)

LENZE84D.GSG (German)

LENZE84D.GSE (English)

Defining the user data length

The user data length is defined during the initialisation phase of the master.

The communication unit PROFIBUS supports the configuration of max. 8 process data words (max. 16 bytes).

The user data lengths for process input data and process output data are the same.

•The DIP switches can only be accessed when the drive unit is detached from the communication unit. Loosen the four fixing screws at the drive unit.

Observe the notes in the mounting instructions.

•Switch off the voltage supply of the controller and the external supply of the communication unit before starting with the disassembly of the drive unit.

•The DIP switches are only read in when the device is switched on.

6.3.1Receiving the station address via the master

Set the DIP switch S = OFF, in order to receive the station address automatically via the master.

The station address active at the PROFIBUS is displayed in C13864.

The settings of the DIP switches 1 ... 64 have no effect.
