LED FX
2N
-10GM FX
2N
-20GM
POWER
Lit while power is normally supplied.If this LED is not lit even while power is supplied,
supply voltage may be abnormal or power circuit may be abnormal caused by invasion
of conductive foreign objects, etc.
READY
Lit while FX
2N
-10GM is ready for receiving
diversified operation commands.
Extinguished while positioning is being
performed (that is, while pulses are being
output) or an error is present.
READY-X
Lit while X axis of FX
2N
-20GM is ready for
receiving diversified operation commands.
Extinguished while positioning is per-
formed by X axis (that is, while pulses are
being output) or an error is present.
READY-Y
Lit while Y axis of FX
2N
-20GM is ready for

Extinguished while positioning is per-
formed by Y axis (that is, while pulses are
being output) or an error is present.
ERROR
Lit or flashing when an error has occurred
during positioning operation.
You can read error code on a peripheral

Lit or flashing when an error has occurred
during positioning operation by X axis. You
can read error code on a peripheral unit to
check contents of error.
ERROR-Y
Lit or flashing when an error has occurred
during positioning operation by Y axis. You
can read error code on a peripheral unit to
check contents of error.
BATT
Lit while power is turned on if battery volt-
age is low.
CPU-E
Lit when a watch dog timer error has occurred.
[Estimated causes are invasion of conductive foreign objets, abnormal noise or low bat-
tery voltage (only in FX
2N
-20GM).]
