The driver made the motor controller accessible from the PI-800 app. But one of the first things I then did was touch the 'load default values' button of the app. This immediately loaded the values for a 72V motor on the 48V motor that I happen to have, without any attempt to probe the actual motor, controller or voltage of batteries that were attached, grr. After that my previously running system stopped working, giving 12 LED/sound flashes ("abnormal throttle input"), even after I selected 48V in the app and downloaded these settings. These beeps are likely caused by the throttle range protection that is now enabled, I recall that this was off before. I have a pot meter attached, and boot with 0V, which is lower than either of the 'lowest allowable" and "lowest exit" values (and I now see that 'pot meter throttle' is an app setting).
I have the following questions:
1) Just to get this out of the way because it does not seem to be the case, but is it possible for PI-800 to cause permanent controller or motor damage, by setting 'wrong' values? (see also question 4 on motor parameters:))
2) Could someone send me a .foc file with the original 48V motor controller settings? I have the current settings that the app gave me attached, but feel safer starting experiments from original factory settings that were working for me.
3) Is there a user manual for this programmer, explaining the different settings? The help popups in the app are often, but not always completely explanatory.
4) The app seems to allow altering motor parameters such as number of pole pairs and rated motor speed, but these seem to be motor hardware characteristics, not parameters that make sense to change.
My nr of pole pairs is set to 4, is this the amount of motor coils? I have three.
5) Is there any way to tune motor performance, e.g. by playing with motor current settings? My settings now include a 280A max phase current, zero seconds duration.
What exactly is the boost function?
Thanks,
Juul
