Greetings!
I could use some advice when it comes to properly wiring up my Maker-Grade CNC Setup:
The setup consists of an Inventables X-Carve with the most notable upgrad being a 0.8kw HuanYang ER11 Spindle hooked to a 1.5kw HuanYang GT Series Inverter with the latter being fully controllable by the X-Controller ( automatic start/stop and rpm )
Generally speaking I'm having no issues with the machine even though the only shielded cable in the system right now sits between the VFD and the Spindle ( 4 Pole U/V/W/GND+Shield ). At some point or another I'll probably at least be upgrading the signal wires between the X-Controller and the VFD - Just to be on the save side.
Powerline:
One issue I'm currently having lies with how I access the Server for files or the iNet for information while I'm in the basement which is done via a Powerline Adapter hooked to the only 220V Socket available to me - The same Socket everything else ( Laptop, Controller, VFD, VAC, etc... ) is hooked onto - Once the Controller/VFD are being switched on the Powerline Adapter looses connectivity - Any suggestions if at all and how this could be remidied?
Shielding:
According to the VFDs Manual (
http://www.hy-electrical.com/BF/GT%2...s%20manual.PDF ) on
Page 20 - 4.6.3.1 Noise control it mentions:
It is strictly prohibitive to connect the twisted shielding layer to the ground of inverter, which greatly decreases or loses the shielding effect.
Soo... Any lead coming off a cables shielding layer should then be connected to where if not a Grounding Terminal?
From my understanding the Shielding Layer needs to be grounded SOMEWHERE but I'm uncertain as to where with the most obvious choice not actually being the proper one.
For static purpose I've ran a desoldering wick through the VACs hose and attached the end to a lead connected to a 220V Ground Plug - Should I do the same for the shielding of cables? Run an extra cable to a Plugs Grounding Pin?
Thanks in advance! =)
