Message: U axis locked up
Detection
During execution.
Effect
It stops the movement of the axes and the spindle, eliminating all the enable signals and canceling all the analog outputs of the CNC. When detected from the position loop, it opens the position loop and sets the LOPEN mark to ·1·.
If it is in execution, it interrupts the execution of the part program of the CNC of its channel.
Cause
The CNC tries to output the command to the drive when the spindle input SERVO(n)ON is still low. The error may be due to an error in the PLC program where this signal is not properly treated or that the value of the axis parameter DWELL(P17)
is not high enough.
