ModBus Transmission
Speed

The ModBus transmission speed is adjusted through parameter SY.07 in the frequency
inverter control. During initialisation this value is read out by the ModBus operator
together with the inverter address and the value is taken as ModBus bitrate.

No Default value of serial interfaces on Perso-
nal Computers

The KEB-ModBus operator is a slave interface. The required ModBus address for
addressing is determined by the operator parameter 

MDB_SlaveAddr_OP

. If the value

of the operator parameter is equal to 255(decimal), the ModBus address is taken from
the inverter address (SY.06). If SY.06 shall have the value zero which was reserved for
broadcast at ModBus, the ModBus operator disable all ModBus activities. If the values
are unequal 255(decimal) the ModBus address is directly taken from this value.

1.3

Diagnosis Interface

Attention !!!

To prevent the damage of the serial interface on your Personal Compu-
ter be sure that you use the special HSP5 cable from KEB for connecting
your PC to the diagnosis interface of the ModBus operator.

With an adapter the HSP5 cable is connected to the diagnosis interface (see ordering
informations). When connected correctly access to all parameters of the frequency
inverter is possible using the PC-software KEB Combivis. Also the operator internal
parameters can be read out and partly adjusted or parameterized with Download.

2.1

Slave Addressing

The addresses of the parameters (register) are devided into different groups. Each of
this group has its own accessing method:

0000(hex).....1FFF(hex)

: This group is build up by those parameters that are accessed

through the mapping list. For a possible adaption of existing applications, the real
start of the mapping parameters in this range can be adjusted by parameters
MDB_MapStartAddr_Rd/Wr ‘. (see below).

2000(hex).....5EFF(hex)

: In this address area the parameters of the inverter control

board are mapped by a fixed algorithm. Access is always made on:

FI-Parameter Address = ModBus Register Address – 2000(hex). 

Please keep in

mind that in this address area access is done with indirect set addressing (with
FR.09). This means when writing/reading one parameter in different sets you have to
set the set indicator (FR.09) previously before access.

5F00(hex)....5FFF(hex): 

This block consists of the operator parameters.
