    "The drive answers the Modbus functions 03 (read), 06 (write one register) and 10 (write several); a parameter GG.nn is the holding register 0xGGnn (Pr.04.01 is 0x0401), and only one parameter can be read per request.",
    "Factory serial format is ASCII 7N2 at 9600 bit/s, station 1 (Pr.09.04 = 0). This map assumes RTU 8N2 (Pr.09.04 = 3), so set that parameter on the drive first; the baud rate and station are not changed by it.",
    "The manual's address list gives units only for current and voltages (one decimal). The 0.01 Hz scale of the frequency registers follows Pr.01.00 and the other frequency parameters, which have two decimals.",
    "The control word (0x2000) and fault bits (0x2002) are write-only; they are listed as bit fields of the same register. To start, write run and direction together in one 0x2000 write.",
    "To control the drive over the link set Pr.02.00 = 3 (frequency) and Pr.02.01 = 3 or 4 (run command). Only the most used parameters are listed; any other parameter can be added by its GG.nn address.",
