You may use the limit switch inputs to the Jaguar speed controllers IF you are controlling the Jaguar via a CAN-bus connection. You can not use external limit switch inputs to the Jaguars if you are controlling them via PWM inputs.

My question is with the wording of the Q&A response. Either the grammar is not correct, or the GDC was trying to be helpful and share a (possibly not correct) limitation of the Jag's capabilities that does not seem to be documented in any of the Jag literature.

"You may use the limit switch inputs to the Jaguar speed controllers IF you are controlling the Jaguar via a CAN-bus connection."

"You can not use external limit switch inputs to the Jaguars if you are controlling them via PWM inputs."

I can find nothing in the Jag literature that says you can not use the limit switch inputs when commanding via PWM.

Did the GDC really mean "can not" or did they intend to communicate "shall not" or "are not permitted to" ?

Does anyone know if the limit switch inputs on the Jags work when the Jag is being commanded via PWM? And if so, has there been a clarification from GDC as to whether they intended to prohibit such use?
