I am running a system with an ASI BAC2000 controller and a Sempu T4.3 quadrature torque sensor. I've scheduled a few meeting with ASI support already and I still can't get it to work properly. They (ASI support) did say that Sempu is a problematic sensor for them. Since it's a fairly popular sensor, I thought I'll try my luck here to see if anyone has experience with the two.
I've scoped all signal wires to confirm my Sempu is working as it should, my controller detects the two speed channels fine with the PFS and Cruise inputs (digital inputs bit 3 and bit 4). I am able to use the Sempu as a throttle input, so the torque signal is definitely fine too. The problem is that the average pedal cadence and average pedal torque reading are always 0.
My Setup
Bacdoor version: 1.15.3.0
Controller software revision: 6.012
Command Inputs tab
Control command source: 3 (BB torque sensor)
Pedal Torque Sensor tab
Pedal sensor type: 3 (Quadrature torque)
Pedalec Torque symmetry: 2 (Quarter cycle)
Pedal speed sensor pulses per rev: 24 ppr
Pedal sense delay: 2 counts
Pedalec power gain: 4
Torque sensor gain: 60 Nm/Vo
Pedalec deadband torque: 1 Nm
Pedalec initial torque: 0 Nm
Pedal speed map offset: 0.75 pu
Torque sensor offset: 1.5 Volts
Control Loops & Tuning tab
Speed regulator mode: 2 (torque mode with speed limiting)
Can someone also explain how "torque reference" and "torque command" are calculated? I've also been seeing the mention of a 65 page BacDoor user manual, but I am unable to find it. Can someone provide a link? Thanks!
