Spindle Amplifier indication 15

NOTE
*1 Note that the meanings of the Spindle Amplifier indications differ depending on
which LED, the red or yellow LED, is on. When the red LED is on, the Spindle
Amplifier indicates a 2-digit alarm number. When the yellow LED is on, the
Spindle Amplifier indicates an error number that designates a sequence problem
(for example, when a rotation command is entered with the emergency stop
state not released).
See “Error Codes (Serial Spindle).”
*2 For serial spindle alarms with a number not listed, refer to the following
documents depending on the spindle motor to which a connection is actually
made.
