Re: Jaguar Non-FRC Firmware

Tested voltage mode but unplugged the Ethernet cable when I got frustrated to see that the jaguar kept running. I think I just have a bad firmware version.
Are you configuring the PID constants? By default they are all 0, so no matter what speed, position, or current you tell the Jaguar to hold, it will not move with P, I, and D set to 0. Are you wiring up the appropriate sensors for position and speed modes? Are you configuring those sensors properly (number of encoder ticks, turns of the pot, etc.)?

Do you have a Black Jaguar? I would recommend trying to control the Jaguar with BDC-COMM first. You will have to make your own serial adapter, but the instructions and part numbers are available in the MDL-BDC24 Getting Started Guide.

This way you can get the various modes working and then troubleshoot your own method of connecting to the Jaguar. BDC-COMM offers an easy way to see what parameters need to be set to get the modes to run correctly.

Without more detail on what you're doing, I can't help troubleshoot the problem.

We only have the latest firmware versions on the web.
