Re: Why are Limit Switches outlawed with PWM, but not CAN?

I'm pretty sure your understanding is faulty. From everything I have seen in action and read in the available documentation, the limit switch action is entirely independent of any commands to the Jaguar, either by CAN or PWM, whether FMS is involved or not.
