Hello przemo33. It appears to me that all we know at this instant is: Your 635's vacuum fan motor does not remain in operation when it should. The fault can be in the 'motor', or due to a resistive connector contact, a broken wire, a failed transistor switch, or a faulty MCU port.przemo33 wrote:Hello, ...I have a problem with a motor during operation Bin Vacuum switches on and off for a few minutes (less time and once more).
I'm not sure why you ask about "BiT#17". That one applies to particle debris sensing. Bit#18 runs the Fan motor test.How to Turn on 17 Built-In-Test is operating normally.
To my knowledge that information has not been made public. Any way, your fan-motor troubleshooting can proceed nicely without that datum.Pin MCU which is responsible for the Init Vacuum Motor?
I do not have any direct reply that associates intermittent fan-motor operation with your described RESET response.In addition, you can not perform a reset by the (SPOT + DOCK 10s)... a reset is not quenched CLEAN and silent melody, ...

Welcome!przemo33 wrote:Thanks for the reply,
Sorry, that is not clear to me, so I mentally translate it to say: "... (of course 18) then the Fan Motor is running normally as long as I wish."When you turn on the Built-In-Test (of course 18) when the engine is running normally all the time,
...I obtain this meaning from those words: "However, by pressing CLEAN, to start a cleaning mission, once again the vacuum Fan did not work."However, during the operation (by pressing CLEAN) and once again did not work.
...I must presume that you used a voltmeter across pins of J6 to confirm Fan Motor power reaching that point. If so, what voltage did you measure?(voltage occurs once and once there J6)
I think you have shown all suspects in my earlier posted sentence: "The fault can be in the 'motor', or due to a resistive connector contact, a broken wire, a failed transistor switch, or a faulty MCU port", to now be clear of guilt. Hence, some other (non fan sub-system) cause for 625's problems must be found. See my closing sentences....What can I check and how?
iRobot provides no alternate command options that can be run while the robot is processing Clean-Mode firmware. Maybe some other rr-member will post an idea.Is it possible to somehow get around to turning it on, or in some other way?
For now, simply R&R the battery to accomplish a system reset. The two-button-press Reset should become operational after you correct what is really bothering the robot.Oh, and what about this "reset"?

I think "12V" is way too low. This low value suggests your battery is not able to properly power the Roomba!przemo33 wrote:...When I turn on the Built-In-Test (test 18) - the engine is running normally all the time without break. (J6 voltage 12V)...

"Running 2 hours" gives the battery a good report--so long as the test was for the robot running a cleaning mission for two hours; ELSE, a poor report, if battery simply operated the Fan Motor and operating system in BiT-mode for two hours. Please clarify.przemo33 wrote:The battery is OK, running 2 hours
Sorry, but I do not have the R3-Fan-Motor Sub-system schematic, so I can't be emphatic (like I know precisely what I'm talking about), BUT, I expect for you to measure almost the full (maybe one volt shy) battery voltage across a running R3 Fan Motor. I doubt that the R3 schematic is greatly different than what we have seen in R2-Roomba. For reference, here is the R2-schematic: Refer to this post to see or copy the entire image: viewtopic.php?p=29586#p2958612v is on pins Vaccum Bin
That is a very large change in voltage! Your 625's Fan Motor may be ailing, i.e., drawing way too much current. Or, there could be a fault in the motor-driver circuit that shows only when its transistor switch ("Q79", I believe you said) is commanded ON.unplugging it as it is about 15V
If you know how to translate that stuff into something meaningful, you will obtain the allowable current limits for your R3-Roomba's Fan Motor operation. Reading the line backwards, it says:page-46 Service Man'l wrote:SUMMARY: (vacuum-current-ok?) PASS mA -143 min -230 max -50 mV 15947 degrees-C 37
