OVERCURRENT
THROUGH DC LINK An overcurrent flowed in the DC Link of the input
circuit.
CPU MEMORY
ERROR The CPU internal data memory is erroneous. The
CPU internal data memory is checked only when
power is first turned ON.
SPINDLE RANGE
SWITCHING/SPIN-
DLE SWITCHING The spindle speed range or spindle switching
sequence is incorrect.
RAM ERROR External RAM data is erroneous. External RAM
data is checked only when power is first turned
ON.
EXCESSIVE OFFSET
FOR U-PHASE CUR-
RENT DETECTOR The offset for the U-Phase current detector is too
large. The offset is checked only when power is
first turned ON.
EXCESSIVE OFFSET
FOR V-PHASE CUR-
RENT DETECTOR The offset for the V-Phase current detector is too
large. The offset is checked only when power is
first turned ON.
SERIAL DATA
TRANSFER ERROR Serial transfer data is erroneous (e.g., when NC
power is OFF).
SERIAL DATA
TRANSFER
STOPPED Transfer of serial data has stopped.
SPEED DETECTION
SIGNAL A disconnection alarm for Cs contouring control if
the speed detection signal is erroneous (e.g. due
to improper adjustment).
POSITION CODER
SIGNAL A disconnection alarm if the position coder signal
is erroneous (e.g. due to improper adjustment or
incorrect setting).
POSITION DETEC-
TION SIGNAL A disconnection alarm for Cs contouring control if
the position detection signal is erroneous (e.g.
due to improper adjustment).
SHORT PERIOD
OVERLOAD An overload was applied during a certain period
(while the spindle was clamped for positioning).
OVERCURRENT
INPUT An overcurrent flowed in the input circuit of the
power supply module.
SPEED DETECTION
SIGNAL A disconnection alarm. The motor cannot rotate at
the commanded speed due to excessively low
speed or a clamped motor alarm.
SERIAL DATA
TRANSFER An LSI internal RAM error for serial data transfer.
LSI internal RAM is checked only when the power
is first turned ON.
