 "summary": "LS Electric's general-purpose variable frequency drive with a built-in RS-485 port that speaks Modbus RTU or the LS INV 485 protocol. Monitoring sits in the S100 common area at 0h0300-0h037F, run/stop and frequency commands at 0h0380-0h03DF, and every keypad parameter has its own address per group (dr = 0h1100, CM = 0h1700, Pr = 0h1B00). This map covers the S100 common area, the trip/warning bit words, and the parameters needed to put the drive under Modbus control.",

  "note": "The manual prints communication addresses in hex (0h0300, 0h1103). Its only Modbus-RTU worked example writes Acc time (0x1103) and Dec time (0x1104) with starting address 0x1102, labelled 'Starting Address -1 (0x1103-1)', and the CRCs printed for that request (0x1202) and response (0xE534) are the correct CRCs for 0x1102, so the wire address is the printed address minus 1: 0h0380 frequency command is sent as 0x037F. The protocol text only says the starting address is the communication address; this map follows the worked frame. The manual states no different rule per area."

  "Left out: 0h032E/0h032F energy (0.1 kWh and MWh registers; how they combine is not described) and the parameter-group registers other than those needed for setup.",
  "0h0305 and 0h0306 hold packed 4-bit and 8-bit fields rather than single flags; the 'bits' entries name the lowest bit of each field.",
  "Pr.13 Lost Cmd Time (0h1B0D, 0.1-120 s) is not included because its register scaling is not printed; set it on the keypad.",
  "The frequency command registers (0h0005, 0h0380) are never stored, even with parameter save; to keep a frequency through a power cycle set dr.07 = 1 (Keypad-1), write dr.01 at 0h1101 and save with 0h03E0.",

Use the S100 area at 0h0300+ instead.",
  "The manual prints a scale of '0' for 0h0312 output rpm, 0h0313 feedback speed and the 0h0340-0h0345 time counters; this map reads that as zero decimal places (whole rpm, days, minutes).",
  "CM.04 option 1 (D8/PN/S2, two stop bits) appears in the chapter 7 parameter description but not in the CM group function table."
