HELP!

 Have been retrofitting a machine and have been stuck on a problem for just WAY, WAY too long. Somewhere on this forum there are Q&As with Bob & Steve helping me while trying to connect my spindle back in the spring/summer. Tried to reply to it but I guess the topic is closed or something. So .... here goes again.

 Everything else is connected and working properly except for controlling the spindle speed am still in desperate need of help on that. Only thing I can think to do is rip everything out and start from scratch with fresh information.

Here is what I am running.

-  MACH 3 (latest rev)
-  ESS - Ethernet Smooth Stepper
-  PMDX-126
-  PMDX-107
-  A/C Servo drives on X,Y&Z (working)
-  GE/FUJI AF-300E$ spindle drive w/ 18,000 rpm 10hp colombo spindle.


I've been able to get my Mach3 setup pretty far along for someone who doesn't know the first thing about electronics, but please disregard that thought. I really need a remedial lesson in the simplest form.

Thinking the problem is the PMDX-107. But not sure. YES I did perform the spindle test/adjustment.
My spindle is wired and set according to the PMDX-107 Manual and all the software is set according to the AN002 addendum as far as I can tell. Have played with the numbers and pulley ratios etc, but it never seems to change things. All settings are back to original recommendations.

There has been NO changes to my spindle drive firmware since connected to the previous controller. As this is a retrofit, the spindle has worked properly on the old controller and have seen it run myself even at a fairly low RPM.

My problem is that the spindle will not run on my mach 3 setup at anything less than exactly 3600 rpm. It will go up to max RPM, but there does not seem to be any science to the RPM after 3600. And it appears to run high, not low.

 Don't know if I have wired something wrong, set something wrong in Mach, set something wrong in my ESS or should have put in some resistors or what???

Attached are some pics that may be relevant.

Ok, Back to messing with my spindle after a summer of working in other areas of the machine.
Pully ratios appear to have no effect on my actual spindle speed. Can't get my spindle to run
at anything less than 3600 rpm. The previous controller that I replaced with the PMDX-126 &
107, ESS & Mach3 would start the spindle much lower. 100 rpm as an example. The spindle
motor itself says it's capable of 24,000 RPM MAX, but think it only really goes to 18,000 RPM.

 Is there a setting in the PMDX, ESS or Mach3 where I can adjust the minimum RPM to lower
than 3600 RPM? Tried everything I can see in all the settings all over Mach3. Won't budge any
lower than 3600 RPM. Maybe I am missing something.

Need help with wiring PMDX-107 to my Fuji / GE AF-300E$ spindle drive.

Also have the other box [pictured] Not sure what it does or if it should connect to PMDX-107 or not.

Spindle drive manual attached

Any help would be greatly appreciated.

Hello, I have PMDX-126 and not finding good information online how to wire this to my AC servo drives.

 I have an industrial CNC router that I am retrofitting to Mach3 controller. Just about have everything buttoned up and rewired regarding e-stop, homes, limits, enable, fault etc.. but I am not getting any motion.
Yes, the drives do work (they move in serial cable setup mode) and they are enabled when I have attempted.

 This is a pinout of C8 (a serial connector on the top on drives) It is used when in GEARING MODE set to PULSE/DIRECTION.

PIN 1 - A+
PIN 2 - A-
PIN 3 - (DC common)
PIN 4 - B+
PIN 5 - B-
PIN 6 - (SHIELD)
PIN 7 - (reserved)
PIN 8 - I+
PIN 9 - I-

Servo Drive: SERVOSTAR S: SR03200-2G203B
Servo Motor: GOLDLINE: M-203-B-23

Picture attached is how I was told by a user on another website to connect to PMDX-126.   Tried, but nothing happened.

HELP!

Hello,

 My machine has 9v inductive sensors for homes on all axis.
They are 2 wire sensors that are in a state of 9v @ 1 mA
with no metal present or 9v @ 3 mA with metal present.

Will these work directly on the PMDX-126 ?
If not, is there a board I can buy to make them work?

Sensors look to be actually 8.2v
Namur SI8-N1 (datasheet attached)

Thanks,

Noob
