Anatomy of a Fault Routine 1
Let's start with a snippet of code:
*AA:
MOVE P,P101,Z=0.0
WAIT ARM
FOR I=1 TO 1000
MOVE P,P102,Z=0.0
WAIT ARM
DO2(0)=1
GOTO *TSA // place of fault
NEXT
MOVE P,P104,Z=0.0
MOVE L,P105
DO2(0)=0
*TSA:
MOVE P,P106,Z=0.0
DO2(0)=0
DELAY 200
GOTO *AA
Some problems can be seen from the code in the figure: in the loop FOR NEXT statement, the jump instruction is rendered,
And did not return to the cycle again, nor did it end the cycle, repeated operation will present the fault of the following figure in the future5.212 warehouse overflow fault, this time continue to operate, there is still this fault, only reset and start over, the way to deal with this problem thoroughly can only modify the program, advocate to modify the following way.
*AA:
MOVE P,P101,Z=0.0
WAIT ARM
FOR I=1 TO 1000
MOVE P,P102,Z=0.0
WAIT ARM
DO2(0)=1
GOTO *TSA
NEXT
MOVE P,P104,Z=0.0
MOVE L,P105
DO2(0)=0
*TSA:
MOVE P,P106,Z=0.0
DO2(0)=0
DELAY 200
GOTO *AA
Some problems can be seen from the above code: in the loop FOR NEXT statement, the jump instruction is presented, and it does not return to the loop again, nor does it end the loop, and the fault 5.212 warehouse overflow fault in the following figure will be presented in the future after repeated operation, and at this time, there is still this fault in continuous operation, and it can only be reset and restarted, and the only way to deal with this problem thoroughly is to modify the program, and it is advocated to modify it to the following way.
*AA:
MOVE P,P101,Z=0.0
WAIT ARM
FOR I=1 TO 1000
MOVE P,P102,Z=0.0
WAIT ARM
DO2(0)=1
GOTO *TSA
NEXT
MOVE P,P104,Z=0.0
MOVE L,P105
DO2(0)=0
*TSA:
EXIT FOR
MOVE P,P106,Z=0.0
DO2(0)=0
DELAY 200
GOTO *AA
There's also an extra line of EXIT FOR loops so that the repository doesn't cause overflows, and that takes care of the problem.
Manually move each shaft, listen to whether there is noise in the mechanical part, if there is noise, check the bearing, reducer gear and other transmission devices; (5) In the state of operation ready to shut off, use the brake release switch to release the brake (note: when the brake is released, the robot arm may fall and cause injury, and the arm that may fall is supported before release), and use the method of listening to the sound to admit whether the brake is released, and if it can be released, the servo drive unit is replaced.
