Hi good afternoon, sorry for my confuse explication.
Let me explain again.
Always at the first time in the morning , we execute a simple program to move all axis and heating the grease.
The problem we have is robot-forum.com/attachment/35892/some axis (number 6, number 3 or today numbre 2) move with strikes (sorry to said jumping) with shorts movements and then produce the error:
(-1504) POSITION ENVELOP JT3
(-1503) SPEDD ERROR JT2
(-1500) JT2 OVERLOAD
Just to get the error, we pass to TEACH MODE and try to move the axis, but it does not move.
Neither JT2 nor anyone.
I'm attaching the screems today 11-02, also i'm sending you a video when the robot try to move (sp 5%), and the stroke you can see, just before the error appears.
When this happen we switch off the cabinet and switch on again. The second time we had a stange very quick movement of JT2 (see video), this has happend today and days before. Then we could move in TEACH MODE the JT2 to marks. Swith off and swith on the cabinet again (4 times) and all worked fine.
This happens in first time in the morning, and later, we are working two swifts witout any issue.
Once it gets moving, it works well all day long.
From the last two weeks we have changed:
1 - SERVO BOARD
2 - POWER SUPPLY AVR (+24 vdc)
3 - BOARD 1DP
4 - GENERAL SWITCH ON/OFF
5 - DIODES OVER CONTACTORS K4-K5-K6-K7
6 - CPU BOARD 9ZA
7 - POWER SUPPLY +/- 5v IN THE SLOTS
Any change, the issue continues.
I thought in the diodes brige for +24V for brakes, thinking about this could fail just in starting.
It isn't easy to check the didoes bridge becuase the terminal are welding and protected.
Thanks for your time, I don't know if this explication have sense for you.
