Re: Position counter stop updating....

Hi Forum

We are still in trouble with this counter stuck/hang
problem. now this problem has become a headache and
soon it'll become a nightmare for us. I guess i wont
be able to sleep well soon!!

We are using STG-II board the latest version of stg.
Does these still have this noise problem with their
Position counters??

After reading Jon's mail I got into my ini and looked
for CYCLE_TIME variable. It was found that this
variable is present
in many sections:
[DISPLAY]
[TASK]
[TRAJ]
[AXIS_X]
[EMC_IO]

I had set this to .001 to task, traj, and to all three
AXIS_X but still having the same problem.

We have connected the Encoder connections to STG-II
board without any filteration using RIBBON cable.
Although the connections of encoder from DC-Motors are
made using a shielded cable.
Encoders of all the three DC-Motors are powered (+5V &
GND) from STG-II.

Our PC body as well as the Machine body is connected
to earth.

One more thing that I've obsereved is when I run the
diagnostic utility found on the harddrive "STG2DIAG"
(which comes from BDIEMC209-01.img)
When I run it with following parameters:

stg2diag index x where x = 0-2
or
stg2diag latch x where x = 0-2

then for x = 0-1 i see such kind of pulse stream:
11100010100001111001010

for x = 2
i see a continous stream of '0' zeroes

This hapens even when there is no motion in these
three axis May be this information is helpful for
forum members to diagnose the problem we are having
with our EMC & STGII

Looking for suggestions

Thanks and best regards

Babar
