4048:SPINDLE ORITENTATION SIGNAL NOT RELEASE
Assumed executing machine adjustment and orientation. If initially, the spindle is
positioned on the sensor, the spindle will move away automatically. After the orientation
signal is off, user will be able to execute machine adjustment or orientation. However, if the
spindle already rotates one cycle but the orientation signal has not been released, then
this alarm message will occur.
(1)Checking whether or not there is connection problem on the spindle orientation
sensor.
(2)Checking whether or not the spindle orientation sensor signal and type setting is
correct (Parameter # 184).

4049:SPINDLE ORITENTATION FLAUT
When executing spindle orientation, the spindle is NOT able to reach the correct
orientation point.
(1)Please go to DGNOS page. If the data system NO. 10 is changing, but the
spindle is not rotating. Then, it means the spindle motor ENCDER signal has
external distribution that makes the system misunderstood.
(2)Please check whether or not the setting orientation rate is too high by parameter
NO. 21 that makes spindle motor has missing step in the Pulse Mode.
