* only applicable to Modbus RTU mode
This parameter can be changed via the drive keypad, via a Solutions
Module or via the comms interface itself. If it is changed via the comms
interface, the response to the command uses the original baud rate. The
master should wait at least 20ms before sending a new message using
the new baud rate.
When using the CT EIA232 Comms cable the available baud rate is
limited to 19.2k baud.
Used to define the unique address for the drive for the serial interface.
The drive is always a slave.
Modbus RTU
When the Modbus RTU protocol is used addresses between 0 and 247
are permitted. Address 0 is used to globally address all slaves, and so
this address should not be set in this parameter
ANSI
When the ANSI protocol is used the first digit is the group and the
second digit is the address within a group. The maximum permitted
group number is 9 and the maximum permitted address within a group is
9. Therefore, Pr 0.37 is limited to 99 in this mode. The value 00 is used
to globally address all slaves on the system, and x0 is used to address
all slaves of group x, therefore these addresses should not be set in this
parameter.
