Yes, this controller has a direct plug in for the CA.Does the 9 Fet controller have a direct plug? (would be really nice)
(I don't really like the extra wires just for some stupid magnet on a spoke and an equally ugly thingy tie-ripped to my fork)
BUT my motor is a geared motor, WITH HALL sensors. (Looks like MAC motor)
Is the analis capable of deviding the motor RPM by a factor 5? So it can measure my speed via the signals in my controller?
You have to use this one with the BMC as it is not a Direct Drive motor. AFAIK the speed only calculates properly with a DD motor. I know I have the CA-DP and wish I would have bought the CA-DPS as I like to use it with my 9c and my BMC setup. The CA-DP works, but the speed shows you as going much faster than you really are....Direct Plug-in with Speedo (CA-DPS): This is a variation of the CA-DP device for ebike setups that can't use the hall signals in the motor controller for the speed sensing. This would include DC motor systems which don't have hall sensors, geared motor setups like the eZee kits where the motor RPM does not match the wheel RPM, and mid-drive arrangements where the motor powers through the bicycle drive chain. It uses a separate speedometer sensor and spoke magnet like the Stand Alone device to pick the speed from your wheel."

#1 is back on the road and now being able to compare back to back, I gotta give mad props to this little 9FET Lyen edition. The thing is so smooth, it pulls strong when it should but doesn't draw excessive Amps and the throttle response is very linear throughout the entire range. The differences are night/day - stock Conhis controller doesn't even come close when used with basically the same motors/throttle.
I never thought there would be so much difference but it's there and whatever Lyen's doing to provide a better controller it's working!
To answer your question... no you cant read values out and your best bet is to just re-flash the controller with known good values. Who knows what bits the last guy diddled.pwbset wrote:Just picked up a used 9fet and despite my efforts I'm not finding anywhere the default values programmed into this controller. My used one came with a programming cable so I'd like to experiment with it this summer maybe pushing up to 35-40A sustained with good, cold Montana airflow , but apparently you can't read in existing controller values just blindly send new values. Previous owner states they're all still default as shipped from Lyen so 30A to the motor I assume. Anyone help out? Thanks!
Yeah, got software/cable etc. Just looking for baseline values to start with. Didn't realize this was "closed" software. That's too bad. We'll see what the CA readings give me once I'm riding.methods wrote:I assume that you got a version of the software from the guy you got the controller from- along with the manual and programming cable.
There are only a total of 36 combinations of hall and phase wires, actually 3 times less genuine ones if you take it relatively. Try different combos with a light brief throttle pull to see if the wheel turns without ill effects. If it turns in reverse direction, swap 2 phases and equal colored hall wires to reverse it back to normal direction. Don't be afraid to try, just don't do it with full throttle or extended time, before you find the correct combo.randel24 wrote:Hey guys, I have been building my second bike for about 8 months,(been taking care of my mom, Long road),anyway, I have last years Ampedbikes rear dd motor and Edward Lyen's 72v 9 fet controller, Edward has been very helpful to me with possible controller and phase combo's, but I am leary of trying them, I am not sure if the setup is MXUS or 9C or other motor. Does anyone have any experience with this setup? I am trying to avoid any unnecessary steps if possible! To avoid ruining anything. Also, I need to know how many poles this particular motor has so I can calibrate my DP Cycle Analyst,also from Lyen. Thank's I want to get this wired up this weekend and this will be my main tranportation when I retire my test mule! I tried to start a new post for this , pardon my noobie'ness. Randel
