Saftronics GP5 VFDs
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
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:

mbpoll
commands to interact with the VFD:
# fault reset ./mbpoll /dev/ttyUSB0 -b 9600 -s 1 -P even -a 1 -0 -r 1 -t 4:int -- 8 # stop ./mbpoll /dev/ttyUSB0 -b 9600 -s 1 -P even -a 1 -0 -r 1 -t 4:int -- 0 # 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
