Maybe N.A. practices are not perfect, but when I transitioned from General industrial electronics to the inception of CNC control and retro-fits etc, some being custom PC based, Galil etc, and...
For Earth GND it is normal practice to set up a star point ground bus of some kind on the panel component mounting frame, for one earth central termination point.
Also see the Siemens publication I...
IIRC he used steppers for his gantry M/C,s , if so the Mach3/4 series should work as a replacement.
I mainly used servo's so I used Galil controllers.
There was one major table manuf that used a GND rod at the machine, they grounded all earth GND's to this point, including the PC based controller, table and pilot arc etc, .
I never saw any...
Looks OK , I assume the DIN rail is showing the entry terminations?
Technically you are required to remove power to motorized equipment in the case a an E-stop.
For cabinet enclosure wiring there is the necessary requirements in NFPA79, there is a copy out there on...
Will see if I still have and send a copy. Do you know what version of 0 it is?
I don't have my Heidenhain catalogues now, but they mainly produced the standard quadrature enc, or the linear absolute versions.
The quickest would be to just send an email to Heidenhain support ,...
Syncros are quite a bit different than quadrature encoders, they operate with two sine waves, calculating the co-tangent between the two.
No re-alignment to do.
I have never seen one using a reference, you are better off going to or converting to quadrature encoder.
That is a synchro resolver it has three windings. used to be used for positioning, but fell out of favour
Generally the proprietary encoders are used on the AC (Red-Cap) servo's.
The DC generally used a standard quadrature encoder.
Not sure of your description of the encoder?
Would need the Fanuc...
I'm guessing he has retired by now, and/or no longer in business, that was quite a few years since he developed his gantry machines!
Well various sources of the manual available show 24v to 80v DC, "A regulated (SMPS) or un-regulated supply may be used, preferably UN-Regulated due to its ability to withstand current surges"
A...
Surely you have the manual for the drives that show the hook up? see attached.
It states 24VDC to 70VDC (typical 36vdc) You will require a bridge rectifier after the Toroidal. The rectified and...
What is the method used to produce the Pilot Arc?
Is it occuring?
Resurrecting and older thread!
Does anyone using the MC2100 board, also use the tach?
I am getting info on the various means to achieve this?
OEM original? or DIY version?
For general Electro-Mechanical parts there is Misumi.
Other electronic parts I mainly use Digikey, they have a flat shipping rate of $8.00 or free over $100.00, customs paid.
They are the modern type of motor, PM rotors, they are AC synchronous servo's.
You don't need a relay, I have a previous post showing how.
The vast majority of my work was for customers, so I could not afford Intermittent problems.
I used one of the very best shielded cables for encoders etc.
Belden 9891. each pair individually...
Not as efficient and can have problems under load, this is how RPC Rotary phase convertors work.
Definitely wrong if 3ph motor!
N.A. 1ph is 120v-0v-120v with the 0v being the neutral, for 240v 1ph , you connect to each of the 120v.
That motor appears to show 3ph?
See the pic in the OP of the terminals, FWD & REV.
I also used what was then the Telemecanique brand of P.B. Switches etc.ZB2/XB2 series, I see that China is now making a knock-off of them.
The enclosures I build uses DIN rail mount devices, It used to be Telemecanique brand contactors etc, , which is now produced by Group Schneider.
Yes, normally you would set up a star ground point that includes the system Earth conductor.
Both VFD GND ands the VFD cable shield would be connected at this point.
There is also a recommendation...
Never had a problem with it, why do you suspect there may be?
The harm is often when the rotor is removed from the stator.
