DOOSAN 240 , ATS BARFEEDER ,BAR CHANGE NOT WORK ON 100 RAPID FEED RATE

Machine: PUMA 240 Bar feeder : ATS EC-565L

the barfeeder works perfect to push the material , so no problem there , When get to the bar change if the machine (PUMA 240) is in 25 % rapid no problem works fine but when is in 100% rapid the barfeeder loads the bar and stop , the machine close the chuck and i get an alarm
what i do not understand is why the same program works on 25% rapid and not in 100% rapid that is where i have the machine set all the time , there is any parameter to adjust or change that does not aloud the barfeeder operate on a 100 %

here is the program i use



START
N1 (STOP)
T0202
M9
G0X.1 Z.02 M5
G4 X1.
/2 M98 P8000
M31
M69
M51
M68
G4X2.
G28 X0 Z0
M1
N2 (FACE AND TURN)
T0303
G0 X... Z...
...
...
...


O8000
(bar change)
M9
M5
G0 X2. Z3.
M31
M69
M51
G4X1.
G0 X.1 Z.02
M51
M68

Do a test:
Make the dwell that is in the 8000 program much larger (say...5sec)
If the problem stop, then itis likely that the m51 relay or its fin (return relay) are acting sluggish.
Check their response time for any delays in either on or off.

If delayed action, replace worn out relay.
If relay is on backorder, use the elongated dwell until relay arrives. (Tune to appropriate time)

i agree with DHARDT increase the dwell after closing the collet 1 sec. might not be enough
as for working at 25% this may be because the rapid over ride can also change the seconds from 1 to about 4 seconds giving you extra dwell

G4U1 is parameter effected.

G4X1.0 is not effected by anything other than machine timing.

The dwell I was referring to was the dwell in between the M51s that are in the reload program (8000)

o i try to increase on prog 8000 to G4 X20. and the same problem also i try a delay between M51 and M68 and nothing same problem


the changes on the program to try
do you mean like that


START
N1 (STOP)
T0202
M9
G0X.1 Z.02 M5
G4 X1.
/2 M98 P8000
M31
M69
M51
M68
G4X2.
G28 X0 Z0
M1
N2 (FACE AND TURN)

O8000
(bar change)
M9
M5
G0 X2. Z3.
M31
M69
M51
G4X1.
G0 X.1 Z.02
M51
G4 U1 (changes made )
M68

What I meant was this:
O8000
(bar change)
M9
M5
G0 X2. Z3.
M31
M69
M51
G4X10.
G0 X.1 Z.02
M51*
M68...

Ignore the asterisk in the previous post.

i try it even with G4 X20. and didn't work , i add another dwell between M51 and M68 and same results .

Are you sure it is jumping into the reload program?

SOLVED


YES is going into the O8000

I solve the problem i find out one keep relay was wrong selected on the type of bar feeder selected and increasing the dwell just to G4 X3. works fine


thanks
