Spun NCal

Shoshana, Michael, Jeff, Tony

We spun the NCal as a life check while we were on site. At first the NCal wouldn't turn on and threw a 'NCal power' error. Power-cycling the motor power by replugging the AC cable running to the Beckhoff motor controller (black cable coming from the left in attached picture) fixed the error. We spun the rotor up to 10 Hz for a few minutes before spinning it down.

NCal Settings:

Motor Frequency Request: 1040 ct

Motor Ramp Gain: 0.01

Motor Low Pass Time Constant: 5

If the Bechhoff error presents it's self hit the system reset button.
