We have had great success with the Super LongBoard utilizing ModBus connection. This would utilize the 2 Pin ModBus port, but we're willing to exchange the 6-Pin with Digital converter for the necessary cable. These are not for the LongBoard, and those can be found here: Sienci Labs Longboard

After having your 2-Pin cable connected to ModBus port on the left side of your VFD, a few changes on your VFD need to be made

By pressing Mode you should see P0.0.00 show up. Using the double arrow to go between the parameter sets, and up and down arrow to change them, and "Enter" to go into the parameter, then adjust with the up and down arrow and Enter again to accept it. It will default to the next parameter automatically. 

P0.0.03 = 2

P0.0.04 = 9

P0.0.12 = 12

P4.1.00 = 4

P4.1.01 = 3

After making those changes to your VFD, you'll need to update/verify settings in G-Sender:

$16 = Spindle Enable

$31=6000 Minimum RPMs
$395=MODVFD
$462=40960
$463=40961
$464=36864
$465=1
$466=2
$467=6
$468=25
