Overview

VFDs marketed by Saftronics, but are actually rebranded Yaskawa GPD 506/P5 drives.

Software

InverterWin is capable of communicating with the VFD over RS-232. A Yaskawa UWR00103-1 cable adapts a DB9 cable to the Hirose header that the interface panel normally mates with.

VFD parameters

Page 41 of the Saftronics PDF also lists all the VFD parameters.
Page 128 (A1-1 in the PDF) of the Yaskawa manual lists all the VFD parameters.
Page 16 (5-1 in the PDF) of the RTU manual explains the Modbus specific parameters.

No.	Value	Description
n002	5: Op Terminal / Ref Serial com	Operation mode select
n103	0: time over detection disabled	MODBUS time over detection
n104	3: continue operation (alarm)	MODBUS stop method at communication error
n105	0: 0.1Hz	MODBUS frequency reference unit
n106	1	MODBUS slave address
n107	2: 9,600 baud	MODBUS BPS selection
n108	1: even parity	MODBUS parity selection

Modbus registers

Page 35 (7-2 in the PDF) of the RTU manual lists the "Simulatenous Broadcast" (write only) registers.
Page 36 (7-3 in the PDF) of the RTU manual lists the "Command" (read/write) registers.
Page 37 (7-4 in the PDF) of the RTU manual lists the "Monitor" (read only) registers.
Page 41 (7-8 in the PDF) of the RTU manual lists the "Drive Parameter" (read/write) registers.
Page 53 (7-20 in the PDF) of the RTU manual lists the "Special" (read/write) registers.

mbpoll

mbpoll commands:

# fault reset
./mbpoll /dev/ttyUSB0 -b 9600 -s 1 -P even -a 1 -0 -r 1 -t 4:int -- 8

# set forward run
./mbpoll /dev/ttyUSB0 -b 9600 -s 1 -P even -a 1 -0 -r 1 -t 4:int -- 1

# set reverse run
./mbpoll /dev/ttyUSB0 -b 9600 -s 1 -P even -a 1 -0 -r 1 -t 4:int -- 3

# set the output frequency (Hz*10, 1003 means 100.3Hz)
./mbpoll /dev/ttyUSB0 -b 9600 -s 1 -P even -a 1 -0 -r 2 -t 4:int -- 1000

# monitor frequency command (Hz*10, 1003 means 100.3Hz)
./mbpoll /dev/ttyUSB0 -b 9600 -s 1 -P even -a 1 -0 -r 0x23

# monitor current output (amps * 10, 53 means 5.3A)
./mbpoll /dev/ttyUSB0 -b 9600 -s 1 -P even -a 1 -0 -r 0x27

# monitor current output (volts)
./mbpoll /dev/ttyUSB0 -b 9600 -s 1 -P even -a 1 -0 -r 0x28
