5.12 Menu 11: General drive setup
These parameters define the parameters that reside in the programmable area in menu 0.
This parameter may be used to scale the value of Pr 0.20 seen via the LED keypad (not via serial comms). Any parameter routed to Pr 0.20 may be
scaled. Scaling is only applied in the status and view modes. If the parameter is edited via the keypad it reverts to its un-scaled value during editing.
This parameter defines which menu 0 parameter is displayed on power-up.
Used to define the unique address for the drive for the serial interface. The drive is always a slave.
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 11.23 = {Si02, 0.67}) 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.
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.
This parameter defines the communications protocol used by the 485 comms port on the drive. 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
protocol. The master should wait at least 20 ms before sending a new message using the new protocol. (Note: ANSI uses 7 data bits, 1 stop bit and
even parity; Modbus RTU uses 8 data bits, 2 stops bits and no parity.)
ANSIx3.28 protocol
Full details of the CT implementation of ANSIx3.28 are given in Chapter 6 Serial communications protocol.
Modbus RTU protocol
Full details of the CT implementation of Modbus RTU are given in Chapter 6 Serial communications protocol.
