Sources: WEG \"CFW-11 | RS-232 and RS-485 Serial Communication Manual\" 0899.5741 (chapter 5 \"Modbus-RTU Protocol\", sections 5.3.2 addressing and 5.4 functions; P0308-P0312 for the serial settings) and WEG \"CFW-11 Programming Manual\" 0899.5620 (chapter 16 parameters, chapter 17 communication). Section 5.3.2 states that the data addressing uses offset zero, so a parameter's Modbus address is its parameter number; this seed stores that number with zero-based addressing. Factory serial settings: P0308 = 1 (address), P0310 = 0 (9600 bit/s), P0311 = 0 (8 data bits, no parity, 1 stop bit) and P0312 = 2 (Modbus-RTU). Integer scaling follows the printed parameter ranges: 0.0 to 4500.0 A arrives as a 16-bit integer with one implied decimal (P0011 is 0.00 to 1.00, two decimals). P0681 and P0683 are 13-bit speed words in which 8192 equals the motor synchronous speed, so they are shown as a percentage of synchronous speed instead of an invented rpm factor. P0682 and P0683 only act when the drive's command and reference sources select Serial/USB (P0105, P0220-P0228), a commissioning step rather than a register. Sixteen-bit parameters only: the SoftPLC markers, floats and 32-bit values are not covered, and the SoftPLC bit markers are reached with function codes 01/05 while this map uses holding registers only, so the coil area is empty. WEG numbers the common monitor/control parameters the same way across the CFW family, so P0001-P0013 and P0680-P0683 repeat addresses that weg-cfw500 lists; the CFW11-specific rows are P0025/P0026, P0030-P0037, P0042-P0050 and P0692."
