Veichi AC310 AC drive

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.

coherence-checked

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: set_frequency @ 8192 — disputed by Weintek/Tecnolog integration guides which state that frequency setting is mapped to 3000H (12288 decimal) and control command to 3001H (12289 decimal) depending on the active communication table

field reports — community-sourced, unverified (checked 2026-06-11)
  • Integrators using Weintek or other standard HMIs must convert the frequency setting address to 3000H (12288 decimal) and the control command to 3001H (12289 decimal) rather than the 2000H/2001H group, depending on the active communication table configuration. [source]
  • confirmed: Baud rates [1200, 2400, 4800, 9600, 19200, 38400, 57600] with default 9600 — confirmed by AC310-I Technical Manual
  • confirmed: Modbus RTU framing with default Unit ID 1 — confirmed by VEICHI AC310 Series AC Drive Manual
  • confirmed: RS485 split into Group 1 (Terminals A+/B-) and Group 2 (RJ45) — confirmed by AC310-I Technical Manual
  • confirmed: Register address 8192 (2000H) for set frequency and 8193 (2001H) for command setting — confirmed by Veichi Modbus RTU Integration Guide
