Fanuc Alarm 459 n AXIS : HI HRV SETTING ERROR
Fanuc Servo Alarm Description
In a pair of axes in which one axis has an odd servo axis number (parameter No. 1023) and the other has an even servo axis number that is adjacent to the odd servo axis number, high–speed HRV control is supported for one of the axes and not supported for the other axis.
Of two axes having adjacent servo axis numbers (parameter No.1023), odd number and even number, high–speed HRV control can be performed for one axis and not for the other.
