After sitting for 3 years I finally got my powerpath under power. Had to do the single board computer upgrade and new hard drive. It comes up and homes. The hydraulic motor and pump sound fine but there is a loud whining/chattery sound coming from the hydraulic distribution block that travels through the hoses as well chuck and tailstock operate and I can adjust there pressures but not sure about the noise being normal or not. The tool turret will unlock a mm d rotate but the light on the encoder never triggers so it just spins infinitely until I e stop. Any sorce on encoders? And after homing I can jog x and z operate the chuck and tail stock and turn the spindle on. But after 5 min or so it will alarm out with an axis fault. The servo drive shows .a72 witch is labeled as overload. Any advice on the first thing to troubleshoot.
