[Mr. Lim]

Jaguars tend to brown-out easily due to a large drop in voltage.

I would first check to see if all your connections from the power distribution board are tight. Check to see if the wires in the WAGO terminal are stripped enough. Sometimes they clamp on the insulation, and supply enough juice to power on the Jag, but once you start actually running it, the resistance causes a big voltage drop.

The screw terminals on the Jags themselves can sometimes come loose as well.

Are you running the Jaguars via a PWM cable? or CAN?
