[Cause]
The parameter (reverse switch) setting is wrong. This alarm occurs during "Search", "Hole Search", and "Clutch Search".
[Countermeasure]
When searching in multiple directions, the reverse switch other than the direction with the highest speed order (the direction with the slowest movement) must be turned on. When the switch is turned off, it is necessary to Turn it on. (Reverse switch) is located on the Search Advanced screen.
