Fieldbus control with the embedded fieldbus 289
Setting up communication through the embedded Modbus
Before configuring the drive for fieldbus control, install the fieldbus according to
instructions given in section Connecting the embedded fieldbus on page 54.
The communication through the fieldbus link is initialized by setting parameter 9802
COMM PROT SEL to STD MODBUS or MODBUS RS232. The communication
parameters in group 53 EFB PROTOCOL must also be adjusted. See the table
below.
After the configuration parameters in group 53 EFB PROTOCOL have been set, the
Drive control parameters on page 291 must be checked and adjusted when
necessary.
