Rectifier/Regenerating Unit    Operating Instructions 
4.5  Starting up optional supplementary boards 
For installation of the board, see Section 9.1, Options for integration into the electronics box. The unit only 
supports 1 optional board of each type. 
Communication-related settings must be defined in parameters. Parameter P052 (hardware configuration) must 
be set to "4" before most other parameters can be set (for further details, see Chapter 5, "Parameter List", right-
hand column specifying criterion for parameter alteration). 
The supplementary boards must then be logged in the unit via P090 or P091. Otherwise they will be ignored by 
the unit and no communication will take place. 
 
4.5.1  Procedure for starting up technology boards 
(T100, T300, T400): 
NOTE 
Freely configurable technology boards T300 and T400 are guaranteed to operate correctly (board runup and 
data exchange with the SIMOVERT 6SE70). The user, however, must bear responsibility for ensuring that the 
system is properly configured. 
 
  1  Disconnect the power supply and insert the board in location 2. 
 
 
2  After the next switch-on, the board must be logged in via P090. The parameters of the technology board 
(d and H parameters) can then be accessed. 
The connections for the process data on the basic unit are made using the corresponding source and 
target connections (see Section 4.3). 
For the meaning of the bits in the control words and the status words, see Section 4.3. 
If a communication board is used in addition to a technology board, then data are exchanged with the 
basic converter via the technology board. The basic converter cannot directly access the data of the 
communication board. The connections for the process data to be transferred are then determined by the 
configuration or parameter settings of the technology board. 
If a technology board is mounted in location 2, then only one communication board (CBC, CBD, CBP2, 
SCB1, SCB2) may be installed in slot G. Other boards are not supported
