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.

Modbus control

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

NOTE: the numbering of some parameters above n100 seem to be slightly shifted between different revisions of the VFD firmware. A physical Saftronics GP5/FP5 Series Instruction Manual (PN 027-2005, Rev 1195, 1995) differs from the "027-2005F" that can be found online.

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.

Address Hex	Parameter No.	Description
0x0000- 0x000a		Command registers (read/write) for broadcasts, first two are Simultaneous broadcast registers (write-only)
0x0020- 0x0040		Monitor registers (read-only)
0x0101- 0x018d	n101- n241?	Parameters (the max parameter is supposed to be n116...)

mbpoll

There is an open source utility that can speak Modbus over a serial port (or USB to serial) that has an RS-485 adapter attached. It's called mbpoll:

https://github.com/epsilonrt/mbpoll

mbpoll commands to interact with the VFD:

# trigger external fault
./mbpoll /dev/ttyUSB0 -b 9600 -s 1 -P even -a 1 -W -0 -r 1 -t 4:int16 -- 4

# fault reset
./mbpoll /dev/ttyUSB0 -b 9600 -s 1 -P even -a 1 -W -0 -r 1 -t 4:int16 -- 8

# stop
./mbpoll /dev/ttyUSB0 -b 9600 -s 1 -P even -a 1 -W -0 -r 1 -t 4:int16 -- 0

# set forward run
./mbpoll /dev/ttyUSB0 -b 9600 -s 1 -P even -a 1 -W -0 -r 1 -t 4:int16 -- 1

# set reverse run
./mbpoll /dev/ttyUSB0 -b 9600 -s 1 -P even -a 1 -W -0 -r 1 -t 4:int16 -- 3

# set the output frequency (Hz*10, 1003 means 100.3Hz)
./mbpoll /dev/ttyUSB0 -b 9600 -s 1 -P even -a 1 -W -0 -r 2 -t 4:int16 -- 1000

# monitor status
./mbpoll /dev/ttyUSB0 -b 9600 -s 1 -P even -a 1 -0 -r 0x20

# monitor drive fault
./mbpoll /dev/ttyUSB0 -b 9600 -s 1 -P even -a 1 -0 -r 0x21

# 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
