The handwheel cannot be used or assigned to an axis successfully, preventing manual control of machine movements.
Click steps to track your progress.
Check if the operating sequence for handwheel assignment is correct and if the feed axis is selected in handwheel mode.
Check the connections on the handwheel for correctness and observe if there are any short circuits in adjacent connections.
Check the interface X10 on the back of the PPU for loose connections, damaged cables, or voltage output of 5 V at the interface (terminal 5/6).
Check whether the handwheel itself is damaged.
If the fault still exists after these inspections, professional replacement and maintenance are necessary as the PPU is likely damaged.
