The bits in the value of Serial Mode (M02) define the data format as follows.:
Bits
3
Number of
Register mode
data bits
Format
0 = Standard
0 = 8 bits
1 = Modified
1 = 7 bits
Bit 3 is always 0 in the core product as 8 data bits are required for MODBUS RTU.
Bit 2 selects either standard or modified register mode. The menu and parameter numbers are derived for each mode as given in the table below.
Standard mode is the default setting and allows up to 99 parameters to be accessed within a menu. Modified mode is provided to allow register
numbers up to 255 to be addressed.
Register mode
(M x 100) + pp -1
Standard
Where M is the effective menu number (A = 0, B = 1, C = 2 etc.) ≤ 162 and pp ≤ 99
(M x 100) + ppp -1
Modified
Where M is the effective menu number (A = 0, B = 1, C = 2 etc.) ≤ 63 and ppp ≤ 255
This parameter can be changed via the drive keypad, or via the comms interface itself. Changing the parameters does not immediately change the
serial communications settings. See note below for more details.
Serial Baud Rate (M03)
This parameter defines the baud rate used by the serial comms interface.
