SmartBOB controllers and dedicated accessories / Re: VFD spindle controler noise

« on: March 27, 2016, 11:18:55 PM »

Hi Steve and Bob
I installed the ferrite donut and it fixed the problem. The machine is running great so far. So I guess it was electrical noise on the spindle cable.
But I wanted to thank you guys with all my problems I have had and I would recomend your products to anyone.

Thank you very much.

Hi Steve and Bob
I ordered 2 of the ferrite donuts and I hope they will be here by Saturday. In the meantime I will check some of the other things you have suggested. When I get the ferrite donuts should I use 2 of them on the spindle supply cable 1 at both ends or just use 1 of them ? So Ill see what happens.

Thanks

Hi Bob and Steve

I will get back to working on this problem. Thanks for all your help ! I have a couple of questions that you might can answer for me.

(1)  My VFD is a Huang Yang  220volt single or 3 phase. I am running it on single phase 220volt. I have the 2 hot leads going to the r and s terminal inside the Vfd and the neutral lead going to the ground terminal of the vfd. I was reading on another forum last night and saw several threads that stated that the neutral lead should not be hooked up at all. They stated that the ground terminal should go to earth ground. If this is the case then it leads to another question.

(2) I have a older ground rod that is just outside my workshop. I am not sure but I think it was installed for cable T.V. years ago. I am not sure this is a good earth ground . How do I check this ground rod to make sure if it is good?

In the meantime I will try some of the other things you suggested. I will try and send some pictures also.

If I cant get it working do you think the pmdx-424 would solve this problem? I dont want to spend a lot more on this machine. Im on social security and the money only goes so far.


Thanks

Hi Bob
I got back to working on my machine. I disconected the limit switch wires and unplugged the motor cables. When I turn on the spindle with everything unplugged Mach 4 runs good I can jog the axis's and the readout on Mach4 moves just like the axis where plugged in. But if I plug in any axis motor and turn on the spindle Mach4 locks up. So I have no idea how to fix this. I read on another forum that some Chinese spindles dont have the 4th pin on the motor jack attached to ground on the spindle case. So I took the cap off the spindle and sure enough the 4th pin didnt have any wire attached to it. So I soldered a wire to the pin and attached it to the spindle case for ground. But this didnt fix the problem. Also I was wondering how to check to see if my earth ground was good. But I dont know how to check it ?

Thanks

Hi Bob
I will disconnect the limit switch wires and see if that helps. Also the control box is about 4 feet from the spindle. Also when will we be able to home a slaved axis with a limit switch and also gantry squaring . I dont think I can work on this untill Friday. I have to fix 2 lawn mowers and a weed eater before my grass gets waist high.

Thanks

Hi
The motor control box is where the motor drivers and c-10 board and pmdx-411 are. There are no wires running to the vfd from this box.

The motor supply cable to the spindle is the D.C. voltage from the vfd to the spindle.

The motor supply cable is the wire that powers the spindle. And yes I manualy turn on the spindle directly from the vfd.And when I turn on the spindle it locks up mach4.
The A.C. for the vfd is 220v and is a separate circuit from the 110v for the computer and the contol box.

The limit and home wires are not shielded so this might be the problem. I will fix that and any other things you mentioned and see if this helps

Thanks

Hi
Im having a problem that I hope you can help me with. I have wired up my Huangyang vfd spindle controlor and when I turn the spindle on mach4 seems to just lock up. The vfd is not connected to the motor control box it is mounted on a wall about 3 foot from the motor control box and the motor supply cable runs directly to the spindle thru the wire carrier tracks. The spindle wire is shielded cable and the drain wire is connected to earth ground. So I was hoping you could give me some suggestions for getting rid of the electrical noise as that looks like the problem.

Thanks

Hi Bob
I finaly got back to working on the machine and doing the items you requested. Here is a list of my results.
I verified the jumpers on c10 and there were as you stated. I removed the jumper for the pull up/down and left it off.
(1) Ran the 2 motors and after 3 or 4 minutes the motor 1 failed. It was connected to driver 1 and pins 4-5 on c10 board.

(2) Swapped the motor connectors and powered back up. After a minute or so motor 2 failed. It was connected to driver 1 and pins 4-5 on c10.

(3) Swapped the stet/dir wires on c10 board and powered back up and ran for a minute or 2 and motor 2 failed. It was connected to driver 2 on pins 2-3.

(4) Powered off and back on and ran untill it failed again. Checked the temp on drivers and motors and there was no noticeable difference. Motors and drivers were just slightly warm.

(5) Went into config for the pmdx and changed the pulse width to 10us and motors would not run at all. Changed it to 5us and motors still would not run at all.

(6) Then I changed the step polarity to active low for all the motors. And powered back up and ran motors for 30 minutes and no problems at all.

Hi Bob
Im out of town today but I will get back to it friday.As far as the problem with no motors turning I had a while back in order to fix that I had to go into the pmdx config and change the step pulse width to 20 and the motors started working.It was set to 10. But since then I have been having this problem Im having now.

Thanks

Hi
The way the motors are wired is the cable is soldered to the motor leeds and at the end of the cable I have a 4 pin plug that plugs into the control box.So to change what driver is driving witch motor I can unplug the cables and swap them around.As far as motor direction they both need to turn in the same direction.I verifed that this morning.I have run motors both on and off machine and its the same problem.With the motors off the machine the motors will start to run fine but after a while the 1 motor will slow down and run sort of jerky and then will just stop.With the motors on the machine i have been testing it in mdi.When I first start running it is fine but after a few passes back and forth it starts stalling.If I shut it down for a while (a couple hours) and turn it back on it runs fine for a little while and starts screwing up again. If I shut it down when it is scewing up and power it back up right away it is still messed up.So it might be some componet is getting hot and messing up? I dont know how to check the signals coming out of the c10 board. I have a digital multi meter but dont know what to look for. Im not saying its your pmdx-411 its just I dont know what it is. I posted on your forum because you guys seem very knowledable and you have helped me alot in the past.

Thanks

SmartBOB controllers and dedicated accessories / Slaved axis problem

« on: December 15, 2015, 06:25:50 PM »

Hi
Im having trouble with my x axis.It has 2 stepper motors and 2 ball screws so 1 motor is a slave.What is happening is one of the motors will completly
stop when I am moving x axis.Then if i let off of the jog button and then jog again it will start working again but only briefly then it screws up again.I have tried unpluging the motor plugs and swapping the motors and the problem goes to the other motor.So it looks like the motors are good and also the cable to the motor is good.They are both using the same power supply so that isnt the problem.I have swapped out the axis drives and that didnt help.I have swapped to different pins coming out of the c10 board and changed to the coresponding motor number in config and that didnt help.Today I  moved the power supplys and any other components that were running off of a.c. out of the cabinet and 2 or 3 ft away from the d.c. side to see if I had a noise problem but that didnt help.

For the drivers Im using KL-4030 from automation technologies and 425 oz stepper motors.The breakout board is the c10 that came with the kit.
The motion controler is pmdx-411.

The Mach 4 version is 2803 the pmdx is 33.159 and firmware 42.137.

The computer Im using is a Dell optiplex 755.Intel core duo 3.0 ghz 8 gb of ram 64 bit windows 7 pro sp1 and a nvidia graphics card.
In Mach config I dont have anything setup in the input or outputs other than the e-stop button and it works fine.
I dont know what else to check or what to do and I was hoping you guys could help Me solve this before I pull the rest of my hair out.

Thanks
Blair Ballish
On the Mach config for the motors I have it at 16260.1626 counts per, 20 on velocity, .31 on acceleration

Hi Bob
Just to make sure I unpluged the 411 from the db-25 and it seems to be seated good.I re-checked the pin 3 on c10 board and now I get .11 volts when I jog it one way and 5.05 volts when I jog it the other way.Then I enabled the spindle  in mach and checked pin 1 and got .1 volt and then I turned on the spindle and  got 5.1 volts on pin 1.Witch I think sounds right But still no movement on motors.I double checked the wiring on the motors and it looks right.Im getting 36volts to the kl-4030 drivers is there any voltage checks I can do  on the A+ A- B+ B- to see if the driver are outputting anything.
Is there any thing on the motor config I have wrong. Im assuming you can see all my settings on the mach file I e-mailed?
Also I noticed on the mach config-outputs that output 1 has a green check but it dosnt have anything in the other columns saying what its for?
This is starting to drive me crazy but you and Steve are realy great guys to help me so much.If I ever have to buy anything in the future it will be from PMDX

Thank you so much
Blair Ballish

Hi
I checked and I am not getting any signal on the pin 3.And the pmdx is set as motion controler.
I am sending a e-mail with the wiring drawing and the mach file attached to it.

Thanks very much
