CycleAnalyst v3 to FOC Controller

[tomgda]

Hello. I wanted to ask for help to connect the Cycle Analyst to FOC controller (not sabvoton but similar)

The controller does not have a plug for the CA is why I bought the model CA3-DPS with speedometer and shunt.

I drew the following diagram it seems to me that it should be. If something is wrong please please let me know and correction in diagram as it should be

P.S - Sorry for my English. I am still learning

The diagram seems okay - although if your controller has an 'ignition' or 'power' connection you may wish to hook up a kill switch and/or keyswitch.

This kind of setup is addressed in the Guide in this section: "Appendix D. Adding a CA-DP Connector to a Generic Controller".

You can also use the yellow wire in the shunt breakout cable either:

• to connect to a hall signal so you don't need the wheel pickup
  (see section: "Appendix B. Add/Remove Wheel Speed Pickup Sensor") or
• to carry the motor thermistor signal to the CA
  (requires re-soldering the connection on the CA PCB - see section "5.8 Temperature Sensor").

Thank you very much for your answer teklektik

My controller does not have a 'ignition' or 'power' connection and I do not want to open a new (warranty) CA and solder on the PCB the more that I'm not so experienced.

I have a question for my diagram. Is the removal of the line + 5V in the range of controller-shunt (see diagram "removed") is correct ?

Not wanting to solder if your skills need some work is probably a good idea - but opening the CA and soldering the PCB does not in itself void the warranty - it's an expected procedure for some installations.

I'm not sure I understand your question about the 5V throttle connection... there is no place to connect it on the shunt breakout cable so it can't be connected. The diagrams in the doc at the link I provided illustrate the shunt hookup and the shunt internal wiring.

Hey.

I connected the CA as in the diagram (see post.1)

Is it normal that when the system is switched off (main switch) and I turn the wheel CA starts to work at the time. I understand that the motor starts operate as a power generator and launches CA.

How to prevent it?
