== Modbus Control ==

=== 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

<code>mbpoll</code> commands to interact with the VFD:

<pre># reset a fault
./mbpoll /dev/ttyUSB0 1 -b 9600 -s 1 -P none -a 1 -r 8 -t 0

# turn the spindle on
./mbpoll /dev/ttyUSB0 6 -b 9600 -s 1 -P none -a 1 -r 1 -t 4
sleep 0.1
./mbpoll /dev/ttyUSB0 7 -b 9600 -s 1 -P none -a 1 -r 1 -t 4 
./mbpoll /dev/ttyUSB0 15 -b 9600 -s 1 -P none -a 1 -r 1 -t 4
./mbpoll /dev/ttyUSB0 47 -b 9600 -s 1 -P none -a 1 -r 1 -t 4
./mbpoll /dev/ttyUSB0 111 -b 9600 -s 1 -P none -a 1 -r 1 -t 4

# turn the spindle off
./mbpoll /dev/ttyUSB0 6 -b 9600 -s 1 -P none -a 1 -r 1 -t 4

# write commanded "speed" percentage (-20000 to +20000) TODO: write signed 16-bit instead of signed 32-bit which clobbers another register
./mbpoll /dev/ttyUSB0 -b 9600 -s 1 -P none -a 1 -r 2 -t 4:int -- 20000

# monitor output frequency (displays Hz * 10)
./mbpoll /dev/ttyUSB0 -b 9600 -s 1 -P none -a 1 -r 103 -t 4

# monitor output current (displays A * 10)
./mbpoll /dev/ttyUSB0 -b 9600 -s 1 -P none -a 1 -r 104 -t 4

# monitor output power (displays kW * 10)
./mbpoll /dev/ttyUSB0 -b 9600 -s 1 -P none -a 1 -r 106 -t 4

# monitor output voltage (displays V)
./mbpoll /dev/ttyUSB0 -b 9600 -s 1 -P none -a 1 -r 109 -t 4

# fetch minimum frequency (displays Hz * 10) that the commanded frequency gets clipped to
./mbpoll /dev/ttyUSB0 -b 9600 -s 1 -P none -a 1 -r 1104 -t 4

# fetch "maximum" frequency (displays Hz * 10) corresponding to a command "speed" of 20000 (to establish the scale)
./mbpoll /dev/ttyUSB0 -b 9600 -s 1 -P none -a 1 -r 1105 -t 4

# fetch commanded "speed" percentage (-20000 to +20000) TODO: see if this value is clipped
./mbpoll /dev/ttyUSB0 -b 9600 -s 1 -P none -a 1 -r 2 -t 4

# fetch minimum speed limit (RPM) (has no effect when using Parameter 9904 = 3 aka "SCALAR:FREQ" mode)
./mbpoll /dev/ttyUSB0 -b 9600 -s 1 -P none -a 1 -r 2001 -t 4

# fetch maximum speed limit (RPM) (has no effect when using Parameter 9904 = 3 aka "SCALAR:FREQ" mode)
./mbpoll /dev/ttyUSB0 -b 9600 -s 1 -P none -a 1 -r 2002 -t 4

# fetch minimum frequency limit (displays Hz * 10) NOTE: can be negative to have asymmetric limits containing 0. If positive, it creates a deadband above and below 0 (not just above!)
./mbpoll /dev/ttyUSB0 -b 9600 -s 1 -P none -a 1 -r 2007 -t 4

# fetch maximum frequency limit (displays Hz * 10)
./mbpoll /dev/ttyUSB0 -b 9600 -s 1 -P none -a 1 -r 2008 -t 4</pre>
