TSDZ2 OSF for all displays, VLCD5-VLCD6-XH18, LCD3, 860C-850C-SW102.

[mbrusa]

Thanks mbrusa for some great software. I see you have released some new versions addressing bugs recently.

I posted a question on the forum a while back about a potential minor bug in the KT LCD3 version of your software (v20.1C.3-LCD3), but no one posted a response. The bug I have noticed is that the icon for the brake sensors no longer shows on the LCD3 screen when the brakes are applied and the brake sensor is active. I can confirm the bug exists for me across 2 motors and 3 displays so is unlikely to be hardware related.

The brake sensors work and kill the motor power, it’s just that there is no visible icon on the screen. Version v20.1C-LCD3 shows the icon as expected. The only real problem with the bug is when setting up brake sensor magnet positions, I have to flash the older version onto the display and motor to position the sensors using the brake activation icon for guidance, then re-flash to the latest version.

All other aspects of the software are just awesome!

Not having an LCD3, I didn't notice your report.
The same problem also existed with 860C and has been fixed.
I sent you a private message.

New to the Forum... Thank you OSF Developers. I love this motor…

I installed a new OSF TSDZ2 w/ 860C from Electrify Bike on my Trek 8.5DS. 860C firmware is 0.20.1c-4 and TSDZ2 firmware is 0.21.4.

I removed my Bafang 750W BBSO2 and kept the 48V 12.8Ah Mini Shark E-Bike Battery (Panasonic NCR18650BD Cells). The battery is capable of 30 Amps continuous discharge.

I’m riding in Power Assist Mode and can only get 500W max motor power. I’ve been tinkering with settings and graphing Motor Power, Motor Current, and Battery Current on the display to capture maximum values during a ride.

It looks like I’m getting close to 500 Watts of power with 19A at battery and 9A at the motor. 9 Amps at the motor x 54 Volts = 486 Watts. So, that makes sense….

What I’m trying to achieve is, not only more power (750W), but also less human effort required (lighter force on peddles).

Questions: Should I try a different Assist Mode? What variables should I change?

I can add motor temp sensing if necessary.

Thank you in advance….

You are aware that 750W, but even just 500W cannot be continuous.
If using the motor at high power, installation of the temperature sensor is required.
To make less effort you have to increase the assistance level and / or the level amplification parameters.
There is a parameter that increases the assistance at all levels and in all modes, it is "Torque range adj", try setting it to 40.
If you mean less human effort at low cadence, you can try the hybrid mode.

Okay I understood that failure was at speed sensor. And thanks for explaining.

My question was:
Is there other signals than the speed passing between the speed sensor and the motor that interferes the operation of the motor?

There is only a relationship between the speed detected by the sensor and the motor.
The speed is used in the calculation of the acceleration and deceleration ramps.
Ramps are inversely proportional to speed.
Low speed, long ramp times.
High speed, short ramp times.
If the sensor is faulty, by enabling "Assist with error" the motor works, but the ramps are not calculated, they always have a long time.

I tried to disconnect the sensor, after 12 seconds there is "e 8 Speed fault", the message remains for 12 seconds.
This with the new version.

Thank you again. I was just thinking there might be some other function because there are six pins in speed sensor.

I increased Torque Range Adj to 40 and Assist Mode to Hybrid. I like TSDZ2 a lot. The OSF is really slick. 1st photo below is 3-mile test ride with fairly large hill. 2nd photo is 7-mile ride on flat terrain. I think Motor Power is well within limits...

If Orville and Wilbur Wright could have seen this bicycle, they would never have invented the airplane. Totally cool....

Thank you mbrusa...

hey
everything worked nice , during easy ride bike stopped assisting and this error showed up . now display starts but bike is not assisting . after restarting display error is gone but bike motor is not working normally , walk assist works but pedal assist is not . speed is showing up...

what to start diagnosing and not to go blindfolded or break anything ?

If Walk Assist works, there should be a problem with the torque sensor.
To confirm, try in cadence mode.
Then check the adc value of the torque sensor on the display, if it changes by pushing on the pedals.

i did a hardware calibration of Tqsensor getting much better range . then added temp sensor and everything was fine . during test ride nothing bad happened . next day i went on short ride (20 min) and at the end error showed up...then i did software calibration of Tqsensor and nothing helped (64 <--> 260 , adc = 166) . i opened the case to check for damaged wires but everything seems fine . i know it can work with error however am not able to turn this option with vlcd6 . can i hardcode this somewhere in code ? it will be dangerours for motor ? will motor consume more energy or might overheat ?

i see there is something mentioning this error in latest rel ?
should i be interested in ?

I did not understand if E05 error motor check, is always displayed.
However in the latest update, the handling of E05 has been improved to avoid false errors.
If you haven't tried it yet, give it a try.

it appeared , then was gone but motor didn't assist .

 

[pxl666]

can this be set for longer ? i assume this extends walk assist , it could be longer than 3 seconds when pushing bike on steep rocky mountain slope its hard to constantly keep vlcd6 button pressed

 

[mbrusa]

But now with the updated version does it work?

"Walk assist debounce time" can be set up to 250 (25 seconds).
"Brake sensor" must be enabled.
"Walk assist debounce time" must be enabled.

hey
got new release , no luck . went on short trip , bike worked fine for around 25 minutes then e05 and no assist . reboot did nothing . reflash with new fw - no luck . tried torque mode instead of power mode - no luck , then tried e04 assist with sensor error - still nothing ...display shows speed , walk assist works , pedal assist not ... what else can i check ??

 

[mbrusa]

So now the situation is this:
When pedaling, the correct speed is displayed but without assistance, no errors displayed, the assisted walk works.
Did I get it right?
Try it in cadence mode.
Post the ini file.

hey. thank you for help . I think I found the problem. one way bearing in blue nylon got rusty and stuck so the motor rotated with cranks and that apparently was causing an error . got replaced and testing if this was the problem . will report later .
once again big thanks for help .

btw can the moisture come from thermopads or thermoglue ?

I connected the TSDZ2 to my PC using ST-LINK V2, but I got this error screen.
I have no advanced knowledge and cannot solve this, could you someone please help me?

do you take power from battery or from 3v usb? I had similar problems when power was coming from battery . when switched to usb power problem has gone

 

[Elinx]

....I got this error screen.....

It could be solved if your controller has a SWIM port. This depends if you have an old V1 controller.
An easy check is to see if it is possible to change the speedlimit directly on display.
If yes,there is good chance it is flashable.

 

[John_Smith]

Controller uses VLCD6
The power supply is connected to a USB 5V
When connected to a PC, the lamp lights up red, but what does this have to do with anything?

Connecting to 5V didn't work, so I tried connecting to 3.3V, but the PC still wouldn't read it.
The motor works fine when connected to the controller, battery and speed sensor.
Is there something wrong with ST-LINK v2? Or can the VLCD6 not be flashed in this way?

Flashing has nothing to do with vlcd6.
You only flash the motorcontroller with Java configurator
But this is only possible if your motorcontroller is an old type (v1).
The new controller (v.2 from Enerprof) cannot communicate with STlink

Easy check

okay
i have to report - the HF1816 was indeed the problem in my case...

I didn't know that was the case.
Are there any type v1 controllers with 6-pin that I can still buy?
Also, I bought the motor from Enerprof, is this relevant?

Enerprof sells always non-flashable controllers, because he want to sell only EU certified Tsdz2 motors.
This has to do with local German laws and liability in case of accidents.

PSWpower is an International seller and still sell the old v.1 controller.
