MotoCrane ULTRA Error 131: Controller Heartbeat Timeout
The system cannot detect the Controller. Either the Controller is unplugged or the PSU to Controller cable is loose or bad. On the Diagnostics page, zero values for speed, smooth and motor commands on both axes point to the Controller electronics.
Error: red icon, repeated beeps until acknowledged. Fix before you continue.
What to do
- Power cycle the system.
- Check every cable connection, starting with PSU to Controller.
First, always: check every cable and the COM and Power LEDs on each module. Axis: system. Applies to MotoCrane ULTRA.
