Yaskawa V1000 Modbus register map
Compact vector control AC drive with a built-in RS-422/RS-485 MEMOBUS/Modbus RTU slave port. The data table covers the run and frequency command registers, drive status, fault and alarm bit words, live monitors, fault codes and the Enter command, and the parameter registers listed here include the communication settings (H5). This file lists the data table plus selected parameters; the full parameter list is in the manual.
- Protocol
- Modbus RTU
- Defaults
- Per the parameter list: node address 1FH (H5-01), 9600 bps (H5-02 = 3), no parity (H5-03 = 0); data length 8 bit and 1 stop bit are fixed. Slave addresses 0 to 20H are allowed and address 0 is broadcast with no response. Control over Modbus needs b1-01 = 2 and b1-02 = 2. H5-01 to H5-03 need a power cycle to take effect.

Address base. The data table prints hex register numbers and the message examples use them directly as the starting number (a read starting at 0020H uses bytes 00 20 and returns the drive status registers; a write starting at 0001H writes the command word), so the printed number is the wire address (pp. 414 to 416). Parameter registers are the hex addresses printed in the parameter list, for example H5-01 is 0425H. Addresses here are those hex numbers converted to decimal, and each note repeats the hex value. The manual lists only function codes 03H (read), 08H (loopback) and 10H (write multiple registers), at most 16 registers per read (p. 412 and p. 414). Parameter changes need an Enter command (0900H or 0910H) unless H5-11 = 1. Address 1 in the manual is address 1 on the wire.
Word order. The data table gives accumulated operation time and cooling fan operation time as a high word at the lower register and a low word at the next register (0098H and 0099H, 009AH and 009BH), so 32-bit values are high word first. All other rows are single 16-bit registers.
Modbus Poll and the Modbus protocol itself count from 0. The "Wire address" column is the number to type into Modbus Poll.

The register table has every column on this page. The blocks file imports into Modbus Poll. The template JSON holds the same blocks plus unit, scale and access for scripts.

Scale is the number to multiply the raw value by to get the unit. Types with more than one register (32 and 64-bit) follow the word order above.
Open in Modbus Poll
- Download the Modbus Poll blocks file.
- Open Modbus Poll, connect to the device and set its unit ID. In Modbus Poll set Word order to AB CD.
- In the blocks panel on the right, click Import CSV and pick the file. CSV import is a Pro feature. Without Pro, Modbus Poll polls the first 20 values of your blocks.
- The wire addresses are already in the file, so there is no 0-based or 1-based conversion to do.
Once the values look right, export the tag list to Ignition, Kepware, Node-RED, Home Assistant or Voltrus SCADA.
