Register map(s) for this device, with a note of how far each has been checked. Addresses are 0-based, as on the wire. Scale and byte order are confirmed only at the hardware-verified rung.
Round-trips through a real Modbus stack with no overlapping addresses and a word-order-sensitive codec — the map is internally coherent and wire-decodable. Does NOT prove byte-order or scaling match a real device: the emulator is seeded from the map's own types, so a uniformly wrong byte-order still round-trips. Only hardware-verified confirms byte-order/scale on the wire.

⚠ disputed: Heatsink Temp cutout limit is 95 ±5 °C (203 ±9 °F); cutting back in occurs at 70 ±5 °C (203 ±9 °F) — disputed by Programming Guide VLT AutomationDrive FC 301/302 (MG33MO22) which states that cutting back in occurs at 70 ± 5 °C (which is 158 ± 9 °F, not 203 ± 9 °F) [7.4.3]
⚠ disputed: Do not connect cable shield to terminal 61. — disputed by Programming Guide VLT AutomationDrive FC 301/302 (MG33MO22) which recommends grounding the cable screen via terminal 61 (which is connected to the frame via an RC link) to avoid potential equalizing currents, or omitting it, but does not forbid it
⚠ disputed: Register map summary (name @ 0-based address): power_kw @ 16100, power_hp @ 16110, motor_voltage @ 16120, frequency @ 16130, motor_current @ 16140, frequency_pct @ 16150, torque @ 16160, speed_rpm @ 16170, motor_thermal @ 16180, dc_link_voltage @ 16300, heatsink_temp @ 16340, inverter_thermal @ 16350, control_card_temp @ 16390, external_reference @ 16500, feedback @ 16520 — disputed by Danfoss FC102/FC302 Modbus Register Overview which shows that the actual 0-based Modbus addresses are off-by-one (e.g., power_kw is at 16099, power_hp is at 16109, etc.) because the parameter number * 10 represents the 1-based register address
Each rung states what it proved and what it did not. Gray until proven; green is earned by hardware only.
