Software equalizing supervision problem

charon

Hi all,

We have recently bought a IRB6640 ID spot welding robot with software equalizing option. (RW 5.12). We install a servogun which has mechanical equalizition on it. So i change softw_equ = FALSE in my gundata to close this option. Everything seems ok except after every CalibrateTipChange or CalibrateTipWear  i get supervision errors.

Datas which causes supervision errors are tipwear_superv and tipchg_superv are defined at SWDEFUSR.sys and both parameters come with software equalizing option. According to manual :

[TipChg] Data type: switch

Calibration type. This calibration type is used after tip change.

The gun will close and open two times. The first close movement will be slow to find the

unknown contact position. The total tip wear is reset to zero.

If the option Spot Servo Equalizing is selected the difference since last calibration will be supervised. If the difference since the last calibration exceeds the supervision value in the tipchg_superv an error will be raised.

See Setup data for Software Equalizing on page 58.

[TipWear] Data type: switch

Calibration type. This calibration type is used to update the tip wear and adjust the contact

position after tip dress or after welding a number of spots.

The gun will close and open fast two times. The total tip wear is updated.

If the option Spot Servo Equalizing is selected the difference since last calibration will be

supervised. If the difference since the last calibration exceeds the supervision value in the

tipwear_superv an error will be raised.

See Setup data for Software Equalizing on page 58.

I already deselect this software_equalization option by assigning FALSE to softw_equ parameter. How can i get rid off those supervision errrors witout installing system again.

Hello,

 

The simplest way is to increase the supervision datas, tipwear_superv and tipchhg_superv

to larger values, example 10mm.

But I agree, it would have been better if the softw_equ = false had turned the supervision off.

Make a backup, change the value's in all the task's manually and do a Restore.

 

Have had the same problem

Thx a lot for answers. Now it just works fine
