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
P0.0.11 = 6
P2.0.02 = 21
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 = all off
$30 = 24000
$31=6000 Minimum RPMs
$340 = 0
$374 = 19200
$375 = 50
$392 = 6
$395=MODVFD
$462=40960
$463=40961
$464=36864
$465=1
$466=2
$467=6
$468=25
$476 = 1
- If $476 is not available, a neighboring grbl command of $478 spindle address
There are two variations of SLB, the SLB and the SLB-EXT
You'll know which one you have by the presence or absence of the relay highlighted below. The SLB-EXT has the relay.
If you have the SLB, $340 = 0
If you have the SLB-EXT, $340 = 5
We may ask you for a diagnostic report. Here are instructions on how to get that, as well as download / upload firmware settings.
