Documenting Motor Controller

[chadjmccolm]

Context

We don't have a solid documentation for how the motor controller works with the rest of the car and I would like to know:

• what inputs it needs
• what current those inputs will have
• what outputs it gives via CAN or other signals

Our controller is a Kelly Controls KDH14601E. All information can be found online as it is still an active product.

Outcomes

The following are desired outcomes of this investigation:

• pinout of the controller as it applies to our car
• wiring diagram in Altium
• data on CAN signals added to main spreadsheet

Related Issues

This will come together with #17 Wiring Schematic Cleanup to increase the validity and accuracy of the wiring harness so that we have 0 issues down the road.

Pages 8,9,10 are the pin diagrams explaining the output, input, signals, and currents for the J1 and J2 pins

And this might already be known but I’ll throw it in anyways for the RS232 port — “Configurable and programmable with a host computer though RS232 or USB. Provide free GUI which can run on Windows XP/2000, Windows 7 and Vista(recommend using Kelly Standard USB To RS232 Converter).“

I have unearthed this email confirming that our controller is rated for 500VDC: https://docs.google.com/document/d/1H4KAorWFNJrISrr2Zw_n9ERj4ZBQ4eDVmgzVubcDKrc/edit?usp=sharing

Motor controller must be wired into the car as follows for forward only motion: J2: Pins 1 and 2 for power and ground must be given 12V. Pin 5 must be hooked to a 0-5V analog signal for throttle. Pin 6 must be hooked to a 0-5V analog signal for brakes. Pin 9 is used to activate the brake input. J1: 10 and 11 must be hooked to CAN high and low.

This has been tested and function confirmed.
