2.2 Components for assembling a frequency converter

ET 200pro FC

26 Operating Instructions, 11/2007, A5E01100763B AA

Table 2-2 Components of the fail-safe frequency converter with F-RSM

Illustration Components Function

1 Rack, wide The ET 200pro bus modules, onto which the electronic modules are

screwed, must be mounted on the rack.

Lengths: 0.5 m, 1 m

2 Interface module for

PROFINET DP, with bus

module

The interface module interconnects the ET 200pro with the DP master and

prepares the data for the electronic modules.

The unit is delivered with the terminating module, and the interface module

is already mounted on the bus module.

• The bus module is the mechanical and electrical connection element

between the various ET 200pro modules.

• The terminating module terminates the ET 200pro.

The following interface modules are available for PROFIBUS DP:

• IM154-1 DP

• IM154-2 DP HF

3 Connection modules for

interface modules

The connection modules are mounted on the interface modules. They are

used to connect PROFIBUS DP, the electronics/encoder supply and the

load voltage supply.

Available connection modules:

• Direct connection:

– CM IM DP Direct

• ECOFAST:

– CM IM DP ECOFAST Cu

– CM IM DP M12, 7/8"

Interface module for

PROFINET IO, with bus

module

The interface module interconnects the ET 200pro with the IO controller and

prepares the data for the electronic modules.

The interface module and connection module are shipped as a compact

unit. The terminating module is included. The interface module is mounted

on the bus module.

Interface module available for PROFINET IO:

• IM154-4 PN HF

4 Safety Local repair switch

module (F-RSM), with bus

module

The F-RSM is used to trigger the safety functions of the fail-safe frequency

converter through the backplane bus; it switches the power bus for the

following motor starters and frequency converters. An F-RSM must always

be plugged in the system to the left of the frequency converter and can be

controlled only through local safe inputs (Safety Local function).

5 Frequency converter with bus

module

The frequency converter is connected to the higher-level controller by way

of the bus module and interface module; power and motor are connected

using prefabricated cables

6 Terminating module The ET 200pro bus is terminated with the terminating module
