After a total lack of help from our local USA Sabvoton Sinewave Controller dealer-importer -- customer service there sucks, one could say it does not exist. I decided to try to install an older 96v Kelly Controller on one of my Cyclone 3000 motors. As usual I got puncual and to the point replies to my emails to Fany of Kelly controllers.
Over the weekend I kept getting error code 4-2:
From the manual on error 4-2: 1. Incorrect or loose wiring or a damaged hall sensor. 2. Also be caused by incorrect hall angle configuration (60 degree or 120 degree)
From another email:
I have checked the Hall wiring with a continuity multi-meter from the end of the Kelly Hall harness leads to where the 5 Hall wires are bundled and enter the motor. I did this noninvasive like testing with a sharp needle to penetrate the last visible hall wire sheaths. No wiring problems in this zone. I also added a conductive grease to the wire connection junctions.
The Hall angle is known and is entered as 120 degrees. Sixty does not work.
Each time I get done with a Kelly Test Run I am able to hook up my OEM controller and the mid drive motor runs fine -- on pavement and I do riding with the existing Halls & their wirings. The motor has 8 steel magnets. The motor is a Cyclone 3000.
here is the reply from Fany:
If the motor is from Cyclone,we may try to use 12V instead of 5V for the hall sensors.
This type of motor has some problem with the hall sensors signal.
Thanks,
Fany
And as for how to get the 12v hooked I asked:
Hi Fany,
the 12v instead 5v sounds worth trying. Is the following wiring setup satisfactory for getting and using 12v on the Hall sensors:
Reconnect the black and red 5v wires going to Halls using from pin1 of J1 12v to the red Hall wire and from p7 of J1 connect to the black Hall wire?
From Fany,
HI,
NO,Actually I tried 12V for the hall sensors of Cyclone motor for many times.
It seems these motors only can work when we use 12V for hall sensors.
The ground wire is still on J2 pin14.You don't have to change the ground because they are internally connected.
Please just use 12V for the hall sensors instead of 5V.
Thanks,
Fany
It seems with Kelly you get knowledge with punctual customer service -- I like it.
I have got powerful rotation on my Kelly controller-Cyclone setup now. I wonder, does the Sabvoton actually need 12v on the Halls instead of 5v to work good on the C-3000? Maybe I will buck convert the 5v to 12v making a common ground as the Sabvoton does not have an internal 12v 30mA power supply like the Kelly.
