I've been working on my parameters for the new bike -- lately up and down throttle rates and AGain. Yesterday I had a problem where the throttle response didn't seem to start until I had maxed out the throttle. Once it started, it seemed to work over the whole range. Then, mysteriously, the problem seemed to have disappeared today when I went to reinvestigate it.
Over lunch just now, I went to try tweaking the settings some more and the problem came and went. I have no idea yet what combination of things makes it come and go. However, today I was able to restore the settings to some more aggressive values without getting the "pulsing" -- so far, so good. I haven't started on the PAS yet. I'm going to get the throttle fully tweaked first.
I have the throttle set to control torque/current, and so far it seems to hold it steady and not to bounce around too much. I've noticed that when I apply the brake, and power cuts off immediately, it seems to ramp back up really quickly (almost instantly) when I release the brake -- is that how it should work, or should it move the throttle output voltage up at the normal rate? Or is that so fast that I didn't even notice the ramp-up? I'm not sure...
And then a funny thing happened: I was running with the throttle set for about 8 amps output -- watching it on the diagnostic screen with the throttle in and out values displayed -- when I blew a fuse on my battery. It seemed strange to me that it would blow -- I was nowhere close to the fuse value (20 amps). I've been running on the same battery fuses for several months now and this is the first one I've had blow on me. I've normally limited my amps out to values only _just_ below the fuse (really too small a fuse, probably) and never had a problem before. I guess I will go ahead an replace the fuse with a 30amp -- I had planned to do this from the beginning, but the 20 amp fuse never blew. My battery pack should be able to handle 60 amps (actually rated for 69.3 according to the manufacturer of the cells I used) and my controller is a 40 amp, but I just don't use that much power. It just seems a little weird that it blew when I was only trying to draw 8A.
