Fanuc Parameter Assistance

Hello, Im fairly new to Fanuc Servo Motors and drives but i think i've isolated the problem to the parameters...
Can anyone offer advice?

I have a three phase Fanuc Servo Motor Alpha6/2000 without HRV control On a B axis that i am having issues with.
For reference I'm Using a 15-B control and a A06B-6079-H200 Servo Amp, in a closed loop (motor feedback to cnc)

When I switch to manual control of the b-axis, the servo motor quickly rotates, Until the servo amp throws an overcurrent alarm (About a tenth of a second). Again, This is without an actual move command being issued, just a switch to control of the axis. Is there some Torque parameter that could cause this?

Thanks for the help
