Sauer Sundstrand 1090256 AT222010 Controller
 |
The Sauer Sundstrand AT222010 (part 1090256) is a transmission controller used in industrial hydraulic and hydrostatic drives to manage motor torque and speed via electronic control of the pump or motor. Common failure points for this class include power‑supply voltage drops, relay or contactor burnout on the drive output stage, PCB trace erosion from overcurrent, and communication link failures (e.g., CAN or fieldbus). First‑check diagnostics should verify that the controller receives its rated input voltage and ground reference, inspect all relays/contactor contacts for signs of arcing or corrosion, and review any stored fault codes or diagnostic LEDs on the unit.[oss-gpt-20b] |
