The wiring diagram posted on November 30 is incorrect if the 4-wire diagram is used (assuming that the diagram for the 8-wire connection is correct).

I don't have a 34HS9801 motor, so I can't tell you which wires to connect. It is easy to find out how the motor is wired if you use a multimeter. Start by connecting one lead of the multimeter to the Red wire and the other lead to the yellow wire. If the diagram is correct, you should get a low resistance reading. If the diagram is not correct, then you will need to connect one lead of the multimeter to each of the other wires until you find a wire that gives a low resistance reading. When you find the correct wire, you have found the two wires to use for the "A" coil. The next step is to verify which other wires are part of the "A" coil. In the November 30 diagram, the Red, Yellow, Blue and Black wires are shown to be connected to the "A" coil. Connect your multimeter to the Red and the Black wires. Twist the leads from the Yellow and Blue wires together. You should get a low resistance reading, if the diagram is correct. Go through the same process for the "B" coil.

Assuming that the diagram is correct, you would connect the Red wire to the PHASE A terminal on the G203v, the Yellow wire to the PHASE /A terminal, the White wire to the PHASE B terminal and the Orange wire to the PHASE /B terminal. If the motor turns in the wrong direction, exchange the White wire and the Orange wire.

The 34HS9801 motor is rated at 4A. The correct resistor is about 60K 1/4-watt. Any standard resistor that is within 10% of 60K would work. Using less resistance lowers the maximum amps that the G203v will allow. Using more resistance will increase the maximum amps that the g203v will allow. BE CAREFUL, allowing too much current to flow with greatly increase the temperature of the motor and the G203v. Connect one end of the resistor to one Current Set terminal and the other end of the resistor to the other Current Set terminal.

The 34HS9801 motor is rated at 4.1mH inductance. That means that you can use a power supply that produces 64VDC maximum. I recommend a power supply that is 10% less, because of heat, but I don't have that motor so I cannot tell you how hot it will run at 64VDC. Many stepper motors are rated to run at 80-degrees Centigrade. I like to run motors at a maximum of 55-degress Centigrade so that I don't burn my fingers if I touch the motors.

Going back to the diagram. If the diagram is correct, you would put tape or some other insulation on the Blue wire, the Black wire, the Brown wire and the Green wire. Those wires will not be used. They must not touch anything.

To make wiring simple, I crimp an insulated ferrule on to the end of each wire and then I connect each wire to a terminal block.

I'm attaching a photo showing an OrientalMotor PK296-F4.5A motor connected to a terminal block.

thanks tom, mike connect: the connection of cables is 34HS9801 //A RED A-YELLOW// B WHITE B- ORANGE// and all well test and.

I'm using a font, PS-63NR12

relived hello, good friends start again slowly, I'm making the holes that grip angle rail, tomorrow I hope to finish them, to assemble the table.

I also get my pmdx 122, that burned the last time because the power supply instead of giving 17v and 12v gave me the pdmx burn, and my repaired for free, just had to pay shipping from Venezuela.

now mount all the wiring again on my test box but can not get the motors to rotate, see photos here who can help me thanks and regards to this beautiful community XD.

I hope that the images are not very large

WOW!!! The most impressive test box to date!

Do you mind sharing where you get your relay board? and its detail.

Hi KenC thanks. Clearly I can

no installation diagram with 3-wire NPN and this kind of realy

if you buy it help me configure mine lol. because I aller turning head explode as installing and neutralize if reaches its limit.
can you give me a brief: Explanation? what function do the NPN and the resulting pin? pause the process? the driver turns off? shuts down the whole system?

The connection for NPN NC proxi swith is somewhere in this forum... I don't keep track of the info since I am not in any hurry to install mine... :p

Its here, I am using Seans diagram that works perfectly. Have a look here....

http://mechmate.com/forums/showthrea...0&postcount=71

Haven't seen that diagram in a while. One small error on that ... It's really only 12vdc and blue line is ground not -12vdc....which would be a 24vdc differential. Still works perfectly after 7 years on number 28

Today progress
I hope to see it up tomorrow XD

hello ken watch this video, do not know if the connection is good, help me if wrong XD

https://www.youtube.com/watch?v=9IVD...ature=youtu.be

Awesome work, Hevert! I have a bit of friendly competition for next number ;)

@Ken thank Arduino's and Raspberry Pi's for those relays. They are extremely cheap and plentiful on eBay and available in 4, 8 and 16 channel versions.

:Dhi dale, and you started yours? pass me the link to see your progress and help along the way XD

Hello, I start the new MechMate. Here I will report progress

that would be my number MechMate? hahaha

soldier?

http://s2.subirimagenes.com/otros/pr...p_91018751.jpg

or screw?

http://s2.subirimagenes.com/otros/pr...p_91018762.jpg

I can both ways but what would be the best?

Thank you

I would weld it. Screws could come loose.

images seem to be missing.

conection splinder VFD

Hi guys, I need help please. I'm trying my Spindler VFD but in 400Hz max rev is 11520 rpm.

it may be happening?

so what I have connected

splinder 2.2kw

http://sia1.subirimagenes.net/img/20...3325686316.jpg

I hope you can help me thanks

thanks already fixed. I needed to configure the VFD

VFD Setup:
Change PD001 to '0' (source of run commands)
Change PD003 to 300 (main frequency - Hz)
Change PD004 to 300 (base frequency - Hz)
Change PD005 to 400 (max operating frequengy - Hz)
Change PD006 to 2.5 (intermediate frequency - Hz)
Change PD008 to 220 (max voltage - V)
Change PD009 to 15 (intermediate voltage - V)
Change PD010 to 8 (minimum voltage - V)
Change PD011 to 100 (frequency lower limit - Hz)
Change PD142 to 7 (rated motor current - Amps)
Change PD143 to 2 (motor pole number)
Change PD144 to 3000 (rated motor revolution)

Good you fixed it yourself. There's a lot to learn.
You also want to hook it (your vfd) up to a pwm signal (0-10v) card which in turn is controlled from Mach3, that way you can control your spindle speed by means of Mach3 ( so on the screen of your computer).
Otherwise you need to change speeds from your VFD directly ( which can be annoying when it's built in a box) or with a remote turnknob suited for your VFD ( Gerald used this method his first machine).

Only full speed is no fun when cutting. Different materials/cutters need different feeds and speeds.

hello looking for info fox if learned. now thanks for the recommendation, I wonder which card you recommend me to control the speed using Mach3?

Hevert, as there are just too many factors involved, such as material, tool size, tool materials, finishing requirements, hold-down methods, individual cutting habits,... etc there are really not much to recommend on speed.
You just has to experiment with them.

Hi Hevert, you need the PMDX 106 it will integrate with your PMDX122 card and provide you with PWM control of your spindle VFD. You will lose an axis though for this capability. But I assume your not going to use A or B axis so not really an issue unless you decide you want more axes. Alternatively you could just put a POT on your panel, no computer control but really simple. There's a bunch of other ways to interface with the VFD but these are the most simple. You can also click the VFD control panel out of its socket and make yourself a ribbon to remote mount the VFD panel fascia on the front of your box door. That's not a hard solution but often overlooked.

Looks good Hevert...keep it up, you will have a number in no time!
Mark

Hi Hevert, glad to see your progress, now you can't stop. Saludos.

hello friends. Now I'm putting my MM me some errors are coming like (V Groove Guide Bearings) I buy them 3/8. I need the 12mm is that true? I need the 12mm x8? and 6 x 3/8? for Z axis

Thanks I hope you can help me greetings

Hi Hevert 12mm and 1/2" are almost identical. Remember decimal and imperial are abstract concepts you could take measurements in octal or binary or bananas if you wanted to. Get yourself some vernier calipers and measure everything you buy. Ignore the size stamped on the side of drills. Drills are whatever size your vernier says they are. Don't be afraid to ream out and re-tap nuts or threaded holes to suit you. Get yourself an engineers reference or 'black book' or print out some conversion tables and tapping clearance tables.
