LGE SCF PST SPL
SPL : Spindle polygon synchronization is in progress.
PST : Spindle polygon synchronization mode is starting.
#2 : Spindle polygon synchronization mode is being released.
#3 : The spindle speed is being changed in spindle polygon
synchronization mode.
SCF : The spindle speed has been changed in spindle polygon
synchronization mode.
#5 : Not used
LGE : In spindle polygon synchronization mode, the two spindles have
different loop gains.
SC0 : In spindle polygon synchronization mode, the specified speed is
zero.

#0 to #3Cause of ALM5018
ALM5018 can be cleared by issuing a reset. The cause
indication is retained until the cause is removed or until polygon
synchronization mode is released.
#4 to #7Cause of ALM218
If ALM218 occurs, polygon synchronization mode is released.
The cause indication, however, is retained until ALM218 is
cleared by issuing a reset.
#0 : The speed specified for spindle polygon synchronization is too
low. (The unit speed becomes 0 for internal operations.)
PCL : The first spindle (master axis in polygon synchronization) is
clamped.
