For this purpose they have the, so called isolation card that is mounted on the side of the lenze controller heatsink. The 3wires left goes to lenze, the other to mains and 0-10V from CSMIO.

on the isolation card there Is a variable resistor do you know what this does,
ie, could It stop my spindle running at power on?

I think the resistor is only to adjust the highest possible speed of the spindle.

I would try to connect a rheostat (or potentiometer, if thats a common word in english)
to connect between the 10V and 0-10V clamps of the iso-card. Then the spindle speed must
change with the position of the slider. If this works, then you canconnect the 0-10V output from the controller board to the Iso-card. After that you must connect the Rel2 to the hot-wire of the lenze drive and connect Rel3 as a commutator between drive and motor.
Attention, you must wait until the motor standstill and half a second or so, before you can switch the direction.

In my machine I don't have any home or end switches, but I need to assamble some, it where better I can add some linear encoders, but that will last some time.

[chris w]

you are losing me with the modifications I cannot act that quickly (wife, 3kids and a dog all need a bit of my time) but I understand it, thank you, don't stop with the information!!
more questions,
on the large contactor to the right of rl 2/3/4 there is a red wire going in the auxiliary contact mounted on the top and an earth coming out can you see where that red is coming from, also the orange wire going in and coming out of the far right terminal, the reason for this is I need the estop and enable circuit to be right before anything else.

I don't know how many machines exist today, I contacted boxford and I am waiting for a reply I will let you know.
you are very helpful and thanks for the info,
Chris w.

Boxford write to me, that maybe I have the only machine ever made, so don't hope to get any usable info from them. But I think from the numbers, they have made at least 10 or someone have said 16 machines.

I hope, I come to the machine in the next days, then I'll try to draw a little of the wiring diagram at least for the parts, that are not exist in the 190VMC. Maybe the diagram for the 230 would be better, because this machine have a tool carousel like ours.

Hi, should I be seeing a voltage displayed on the Mach 3 screen when the spindle is running, it does display the commanded speed but no voltage.
there is a sensor mounted on the rear of the spindle looking at a disc with holes in it I followed back the wires from that sensor and they go into a terminal rail but nothing comes out, is that sensor only for spindle synchronisation like ridgid tapping??
if there is no voltage feedback could this be the reason that the spindle is creeping when I power up?

As I know the slotted disc is for feedback to the lenze drive via the controller board (the large board with many connectors) I don't think that rigid tapping is possible with this machines, and you don't have as much torque as you need for tapping. The motor has with the small toothed belt gear a maximum of 2Nm. That is enough only for M6 in Alu or M4 in Steel.

I hope I come in the next days to the machine, then I make some pictures and a little drawing of the
part with the motordriver. Why don't you use a Multimeter to see if the voltage is changing from your controller board. If yes, then something in the harness from controller to driver is not ok.

If I fit a potentiometer between the 10v and -10v and it works am I not just covering up some problem that needs fixing by another method I mean if the slider was meant to be there would they not have fit it at the factory?

No you won't see a voltage on the screen but you will see Analog voltage on the Cslabs Plugin control if you want to see the voltage.

Regards the creeping have you set the spindle control up correctly regards Pulleys etc.? You may be getting a Voltage on the pin if not.!
Could be stray noise but I doubt it.

Thou to be honest the Spindle shouldn't be spinning because the Lenze shouldn't run until it gets a signal for the Run command no matter is Ref voltage is being applied or not. The REf voltage should just say run at this speed when you do turn on.!
Are you sure you have it wired correctly.? Does the Lenze have an enable or Run input.?

He said, the wiring is made from a friend, but he hadn't wired the spindle drive correct.
This part should be the easiest of all, but without experience, he shouldn't make anything.
I'll try to make a correct drawing this weekend, maybe then he can wiring it by herself.
