    Just a reminder, it does need to be mentioned that "on is off" and "off is on". That is a stumbling block for the uninitiated since that is not pointed out in the instructions you mention.

    The ADC values are set in another screen. On the 860C it is called "Torque Sensor". Here's what the first page of mine looks like: The assist levels you have shown are way too high. With a human power of 150 watts your demand for current would be 15 amps on your assist level 1. With...

    Nothing attached?? What is your system on, a mountain bike or what? Not sure you have to recalibrate the torque sensors. The ADC values should be the same regardless. You may have to reenter your data but if you saved it from before it should be good.

    Welcome to the board and good luck solving your problem. The "overrun" is an effect from the default assist levels in V1.0.0. I suspect you are using assist at a high level. You likely want to adjust the defaults to a number and level for your application. Using too much assist will...

    New "TSDZ2 Torque Sensor Central Motor"

    Fireflyer451, did you ever figure this problem out? I have the same issue and chased this gremlin as well.

    TSDZ2 860C - Battery voltage displayed is wrong.

    I have had an indication from someone who knows, that the motor controller is what sends the voltage report to be displayed. While there is actual battery voltage provided to the display, the displayed value evidently is being reported from the motor controller over the UART connection. I...

    No, I am not developer. My interest is simply making my significant expenditure I have made work properly. It appears my questions have offended you and I apologize for that. So for the time being I am trying to figure out if I should compensate for the elevated voltage value in the...

    TSDZ2 860C - Battery voltage displayed is wrong.

    For whatever it is worth, I measured voltage at the input pins to the 860C and it is receiving an accurate battery voltage as I expected. So the system is sending actual battery voltage to the display and in my case, the display is then showing a voltage that is 1.5 volts higher. So I believe...

    TSDZ2 mid drive with 860C, 850C or SW102 displays only -- Flexible OpenSource firmware (Casainho code only)

    @casainho, Thank you for your response. Yes, I did find the actual battery voltage being sent to the display. I measured it at the green connector pins that feed the 860C. Unfortunately my 860C then adds 1.2 vdc to that. So my 860C is showing a voltage that is high by a significant amount...

    @vshitikov, Looks like you have explored the details of the 860C and I thank you for the feedback on this issue. Do you know how this error affects the Display's functions and outputs? In other words, doesn't the voltage error cascade into any computed values that contain voltage, such as...

    Need to be sure what you are talking about here. When you say it is the controller board, do you mean the motor controller or the display board?

    TSDZ2 mid drive with 860C, 850C or SW102 displays only -- Flexible OpenSource firmware (Casainho code only)

    My 860c display reads 1.2 vdc higher than actual battery voltage at a high level SOC. The error decreases to 1 vdc when the battery is at 30% SOC. My assumption is that this is a hardware issue. BTW, my battery is a 52v so yes, I know the displays says "Run" at 59.5V! Can someone familiar...

    TSDZ2 860C - Battery voltage displayed is wrong.

    Ref. Battery Resistance - I used the WIKI - see the section on Battery. I sent you a PM on this. Ref. Voltage being displayed too high - I found a thread today that referred to this issue as causing the motor to not run in a non OSF version. It said that the voltage sensor was faulty in this...

    Thanks Hugh, this thread is so long and complicated I have a great deal of trouble finding stuff in it. Unfortunately the board software lacks post numbers/identifiers so that is a hindrance for us to make references to past posts. Could you tell me what date you posted your settings so I...

    Ref. Torque Sensor Calibration - There's a clear statement as to why you need to do it in the WIKI. Calibration will have no effect on overrun but it will make your system perform better. Ref. Settings - Change default of 20 levels to 10 and keep the same Assist Level Factors. Using levels 1...

    I would really encourage you look to see what your settings are. People are not able to help you without specifics. No one knows what it is out of the box except the folks that sold it to you and you, if you go into the settings and look. Such is the world of OSF and the TSDZ2. If you...

    TSDZ2 mid drive with 860C, 850C or SW102 displays only -- Flexible OpenSource firmware (Casainho code only)

    Do have Torque or Power selected in your settings? What actual Assist Level Value does your configuration use for level 8 for example. BTW, not sure what you mean by Red Herring. This is a primary control relationship of the torque sensing system that we bought. There's a lot gathered up...

    TSDZ2 860C - Battery voltage displayed is wrong.

    I think we have the same 52V 21ah battery. I did set the battery resistance per the wiki. Yes, the default was at 300 and my test runs yielded 117 consistently. Therefore I changed that setting. However I believe this battery resistance setting is independent of the battery voltage...

    TSDZ2 mid drive with 860C, 850C or SW102 displays only -- Flexible OpenSource firmware (Casainho code only)

    Are you using your system on a recumbent or DF bike? Can you share your left and right weight vs. ADC value curves that you came up with for your Torque Sensor Calibration work? When you are on assist level 10 and a Human Power of 50 watts, what corresponding Motor Power are you seeing? On...

    TSDZ2 mid drive with 860C, 850C or SW102 displays only -- Flexible OpenSource firmware (Casainho code only)

    Thanks. I like spreadsheets! They give me great visuals. I think the default Assist Level Factors are set a bit too high but so what? We can change them. That is the beauty of this system. I am thinking the deep dive into the table can cause the controller lots of issues and I felt them...

    TSDZ2 mid drive with 860C, 850C or SW102 displays only -- Flexible OpenSource firmware (Casainho code only)

    Please take another look at the relationship that drives the chart. It is motor current (amps) = human power (watts) x assist level factor. That is the control scheme and it is independent of the current limit you choose in the setup. Your 10 amps max current just moves the red zone up and...

    A few of us have reported the “overrun” issue here. By this, I mean the motor continues to add assist for a period after we stop pedaling causing harsh shifting, etc. I experienced this and therefore dug into the Assist settings. As a result, I offer the following: With "Torque" chosen...

    Thanks for confirming the actual numbers you are using. I was trying to confirm that these are the default settings but I was uncertain. I bought my setup for a supplier here in the US and was unsure if he'd changed the settings or not. (fat finger mistake on the 1 - .007, should have been...

    TSDZ2 mid drive with 860C, 850C or SW102 displays only -- Flexible OpenSource firmware (Casainho code only)

    I believe this is an outcome of the "Assist Level Factors" that are too high in the settings under the "Assist Level" screen for configurations. I have asked a couple of other folks who have posted here recently with this issue to share those factors but haven't gotten feedback yet...
