Hi. I'm having some problems with a Heidenhain TNC 145 c... The batteries went off and there was no power also on the machine, so the parameters erased form memory. I replaced the batteries and tried to RE-enter the parameters, following the instructions in the Manual, but when i turn on the machine, after pressing CE, it sais "pass over z- reference mark, pass over y- reference mark, pass over x- reference mark" and nothing moves at all. Could this problem occur because of some wrong parameters? Anyone can help? Thanks.

Hi, I am Shahid. Obviously there are certain parameters which can hold the machine movements. Simply the 42 no param. can hold the machine if its setting is out.It is related to the potentiometer. There are three options for 0, 1, 2. Check all these settings. If it works OK, otherwise let me infrom i will produce you the orignal parameters. My emila is seeco_pak@yahoo.com

That is a start, do you know how to run the machine? Power enable, start start start.....

Well, this is the first time i try to work on a machine like this. I also learnt a little bit of Hurco programing, but that seems much easier than Heidenhain :) I know how to turn on the machine, from the main switch, then i press the CE button so that the "Power Interrupted" message disappear.After that, the message "pass over z- reference mark, pass over y- reference mark, pass over x- reference mark" appears and when i press the GREEN button (start button) and Cycle Start button, the Z axis moves a few millimetres and stops(but the other axes don't move at all). It appears that the Z axis moves randomelly, because sometimes it moves downwards and sometimes it moves upwards(after following the same sequence mentioned above). I tried moving the axes by the handwheel, after pressing the "electronic handwheel" button, but it doesn't work (with parameter 52 set OFF). I really think that the parameters are set wrong...

You need to get a manual


If the Z is at the top of travel, then it is not moving randomly. It will move up until it hits the trip dog, then down to look for th ereference mark.

Continue to hit cycle start repeatedly and the other axis will try to home.

Ok...but after all axes "go home", how do i get rid of the message "pass over z- reference mark, pass over y- reference mark, pass over x- reference mark". I have a manual but some things are hard to understand if you never worked on such machines.
When i try to change from "manual mode" to any other modes, nothing happens. The little red light near the NEW selected mode turns on, but the screen remains the same...with the same message about the reference mark...

if it still says that, you are not homed

power on

"CE"

Power enable

feed rate override at ~100 percent

cycle start [wait]

cycle start[wait]

cycle start[wait

cycle start[wait]

cycle start[wait]

cycle start[wait]


As each axis is homed, with a max of 2 moves per axis, that line should disappear

until it is homed, it will do nothing else

Aha! :) It seems to work now :) I followed the sequence you told me, and the axes home, but after the axes are homed, they still move a little bit, even though the little yellow light ( the "Indicator lamp") is OFF. Now i'm trying to learn how to enter a program into the machine. I'm thinking to sell the machine and that's why i try to turn it on and run a program on it so that the customer can see it works. I'll read through the manual and see how to program it and if i have other questions, i'll ask for your help :D Thanks.

Gugu,
here is a link to the manuals.

Mark.

Question: When entering a program into the memory, how do i enter things like A X 100* R0 F 9999? What button should i press so that i can "type" A X?

First, read the damn manual

Second, A is not a relevant syntax

In programming mode, hit the X key, it will tell you what to do

if it still says that, you are not homed

power on

"CE"

Power enable

feed rate override at ~100 percent

cycle start [wait]

cycle start[wait]

cycle start[wait

cycle start[wait]

cycle start[wait]

cycle start[wait]


As each axis is homed, with a max of 2 moves per axis, that line should disappear

until it is homed, it will do nothing else

Gus...please help me out....when I push the cycle start button on my series 2 intact 2 it does nothing...should it buz or fart or spit....also the feed rate knob is so sensitive that simply touching it will cause a jump from 100 to 80 or 120 etc...this is the first time I have tried to start this machine...I have no idea what behaviour to expect....not certain if I am dealing with a program issue or hardware problems....also a note the air spindle brake will not switch to the off position help....and yes I have read the manual....but it goes about everything as though you are starting with a working machine.
