FN Datasheet, PDF – Alldatasheet
I have an old F11 electric wheelchair, i was originally trying to modifiy the joystick that controlled the motor controller.
I will load pictures of the motor controller when i get on a high speed internet thanks.
HIB where you find the datasheet can you post datasheeh link. Sceadwian Banned Mar 9, Pictures would really be needed, I don’t see why you couldn’t tap into the existing motor controller as long as you’re sure it still works, it should be pretty simple, though I’m guessing you’ll need at least a basic external driver circuit from a PIC to drive it, if nothing else to adjust voltage levels.
When you take pictures make sure you get good shots of all the IC’s on the board or label the picture somehow and type the chip numbers out in text with the post.
Help with motor control
And post a link to the PDF. I will try and post some pictures tomorrow, just gotta get to a high speed connection. The motor controller had a daughter board attached the ran everything, it accepted the serial commands and converted them in to the driving singals. Why do you need to get to a high speed connection? Open them in “paint” and save as jpg’s. Pictures of the motor controller top and bottom, i labeled the back view picture, you need to zoom to see the labels came out alittle smaller then i was thinking but there are very clear when zoomed.
The 16 transistors, are FN, the 2 motor control chips are HIPIB, there is a single transistor that serves as a 12 volt regulator.
I tried hooked my rc reciever directly to the pwm lines for the motor controller but only registered a change of 1 or 2 volts on my Multimeter. Mabye i connected the Reciever wrong, i grounded the grnd in to the ground shared by the rest of the circuit, and then i connected the signal line to the pwm input on the chip.
I will toss together a pic chip tonight and try feeding it a pwm signal from that see if i get any results.
Are you using the same pwm for bolh BLl and ALl you have to invert one of them I drawled it out for you.
Can anyone help me solve my problem?
Sceadwian Banned Mar 14, Apparently your motor is not bidirectional. Does it have a gear head on it? Some motors with built in gear heads aren’t reversable. You can do it with this http: Sceadwian Banned Mar 25, Use a logic inverter? You can make one easy but it takes 4 v1010n to make what he needs.
