Re: Jaguars Blinking Red

The symptom you describe is the Jaguar going into current protection. If the jaguar remains inoperative with the Red LED for about 4 seconds, this is the wait time for the Jaguar to reconnect after a fault. If this is what is happening in your robot, it is a good indication that the CIM motors are geared so high that start current is at or near stall current for a length of time. If this is the case, a wise designer will change the gear ratio to slow things down and keep the CIM away from stall.
