I figured out the problem with the controller. It is the MF switch. If you watch really closely you can see that one of the 5 Pins is bent. If I connect another MF switch that has 5 straight pins the controller and the CA starts right away. I don't think there is a reasonable way to repair the...

Grin did the soldering of the 5-pin connector to the +/- leads of the controller. It looks a little bit different than the old one of my battery pack (they soldered the two outter pins together instead only using one as seen on the right). Does that make any difference?

Hey there, short update: I sent back the Grinfineon Controllers from Grin. I explained the whole story to them and they told me that the symptoms point to something amiss in the motor controller. The controllers are still shipping so I don't know what was the problem in the end. I will post...

Now I think I understood. Sorry, it's just because my technical english (and my english in general) is not really high-end as you might have noticed :cry: Ok, if Grin doesn't answer then I will get an Voltmeter in the hardware store and test the different connector sites (with your help...

Where do you want to test the signal? If the motor ist connected to the controller then there is no open plug to get the signal from... :confused:

I’m wondering how Grin wants to trace back the controller configuration/built.They asked me for the order number to check that but I haven’t gotten an answer back. I think I’ going to wait another day for Grin to answer. I think their opening hours are from Tue-Fri.Maybe I should even try to...

Yes, you can hear a clear audible buzz as soon as the motor starts spinning when the wheel ist off the ground and it pitches up the faster the wheel spins. That is exactly the problem. I could live with the sensorless driving but it is very rough at the start but as soon as I have reached a...

If I do that the flashing persists. I assume then that the controller is mapped incorrectly. That's harsh, having spent days already with configuring the Cycle Analyst over and over again and racking my brain what I have done wrong. :( I've done that already and gotten a short response in...

The controller is supposed to be red constant. This is the sign for sensored mode. My controller is flashing but as soon as you push the throttle or start pedaling it is constantly red, indicating sensored mode. This is also written down on the Grin page. "If the controller LED is flashing on...

No,it is a constant flashing.I ordered two motors with the exact same components. Both have the same problem, so it is quite unlikely that both sensors are damaged. If I spin the wheel the P isn’t blinking. I was thinking that maybe the CA is waiting for a signal from an external speed sensor...

Is there any way I can check if the speed sensor or magnets inside the motor are damaged?

I was hoping that all the components works well together because I bought it as a Ready to Roll Kit from GrinTech. I spent almost 2 days redoing all settings over and over again without a change. The controller stays in sensorless mode with the unsatisfying driving characteristics. I will try...

Dear Forum, today I finished installing my “Ready to Role Grin All-Axle Hub Motor Kit” onto my beloved cargo bike. I'm quite proud of myself since this is my first built and I did everything on my won but my first test ride was very disappointing :| . I'm so sad right right now... :( , I hope...
