Notes

RS-485 device: reach it through a Modbus RTU-to-TCP gateway using the factory serial settings above. MEMOBUS/Modbus defaults from the technical manual: H5-01 slave address 1FH (31), H5-02 = 3 (9600 bps), H5-03 = 0 (no parity), 8 data bits, 1 stop bit; H5-11 = 1 and H5-12 = 0. Register addresses are the manual's hexadecimal MEMOBUS register numbers (zero-based wire addresses). Source: Yaskawa V1000 Technical Manual SIEP C710606 18F, section C.10 'MEMOBUS/Modbus Data Table' and section C.5 for the H5 defaults. Register 0026H (output current) and 0027H (output power) are left out on purpose: the manual states the current unit depends on the drive model (0.01 A or 0.1 A) and gives no unit for output power, so a single scale factor would be wrong for some models.
