I started to compile infos about the EB312 (AS-2) controller, which I intend to use in my new e-bike built. There are many info-rich threads here on ES, however, I still need to ask all those who know more about this controller to help me filling in the gaps. I would like to know all possible input / output signals of this pcb and their relation to the new XPD release. Following a photo of the pcsb's backside, a sketch of the pads/labels including a list of the connectors which are currently mounted:
Here a list of all connections explaining their intended use. It will hopefully be expanded/corrected and the question marks will disappear:
Abbreviations:
BK ? break signal
CR cruise mode signal (connect to GND to activate)
DX ?
EBS+ ?
EBS- electric brake signal (connect to GND to activate)
GND 1-8 ground (multiple pads)
HE hall sensor signal (replacing speedo pick-up for CA (fit QSA/RSA1 !))
LED ?
P1 LED indicator 1 (connect to common GND or VCC) (... does it indicate speed1 ?)
P2 LED indicator 2 (connect to common GND or VCC) (... does it indicate speed2 ?)
P3 LED indicator 3 (connect to common GND or VCC) (... does it indicate CR mode?)
P4 ?
RXD receive data
SA hall sensor signal A (sensor detecting rotor position phase A)
SB hall sensor signal B (sensor detecting rotor position phase B)
SC hall sensor signal C (sensor detecting rotor position phase C)
SL speed limit signal (connect to ground to force overall speed limit to which all other speed limits (X1, X2) are referenced)
SLA ? ; connected via diode (IN4001) to X3 to CA throttle over-ride
SLK1 ?
SLK2 ?
SP throttle set value (0-5V)
TA pedelec sensor A (hall sensor detecting pedal rotation)
TB anti theft mode (connect to GND to activate / lock the motor)
TXD transmit data
VCC-L controller pos. power supply (interrupt to switch controller off)
XC
XC-
X1 connect or toggle to GND to limit speed1 or cycle speed 1-2-3(-4)
X2 connect to GND to limit speed3
X3
X3-, DX3 reverse mode (connect to GND to reverse rotation and limit speed)
X4 ?
+5V 1-5 5V supply (multiple pads)
