MotoCrane ULTRA Error 125: Joystick Failure Error
The joystick output went outside its expected range, so the Controller blocked movement because it assumes the stick has a physical fault. A power cycle is needed to reset.
Error: red icon, repeated beeps until acknowledged. Fix before you continue.
What to do
- Disarm and power cycle.
- Keep hands off the joysticks while the Controller powers up.
If it keeps coming back: If it persists, the joystick or the Controller wiring may need MotoCrane service.
First, always: check every cable and the COM and Power LEDs on each module. Axis: system. Applies to MotoCrane ULTRA.
Code 125 on RADICAL is different: RADICAL Error 125: System Under-Voltage Warning.
