Message
9006 SPN_n_ : THERMAL
SENSOR DIS-
CONNECT
06 1 Check and correct the parame-
ter.
2 Replace the feedback cable.
The temperature sensor of the motor
is disconnected.
9007 SPN_n_ : OVERSPEED 07 Check for a sequence error. (For
example, check whether spindle
synchronization was specified
when the spindle could not be
turned.)
The motor speed has exceeded
115% of its rated speed.
When the spindle axis was in position
control mode, positional deviations
were accumulated excessively (SFR
and SRV were turned off during
spindle synchronization control.)
9009 SPN_n_ : OVERHEAT
MAIN CIRCUIT
09 1 Improve the heat sink cooling
status.
2 If the heat sink cooling fan
stops, replace the SVPM unit.
Abnormal temperature rise of the
power transistor radiator
9011 SPN_n_ : OVERVOLT
POW CIRCUIT
11 Check the input power voltage and
change in power during motor de-
celeration. If the voltage exceeds
264 VAC, improve the power sup-
ply impedance.
Overvoltage of the DC link section
was detected.
9012 SPN_n_ : OVERCUR-
RENT POW
CIRCUIT
12 1 Check the motor insulation sta-
tus.
2 Check the spindle parameters.
3 Replace the SVPM unit.
The amplifier output current is abnor-
mally high.
A motor–specific parameter does not
match the motor model.
Poor motor insulation
9013 13 Replace the SVPM control printed
circuit board.
An abnormality was detected in the
SVPM control circuit.
(Internal RAM request)
9018 SPN_n_ : SUMCHECK
ERROR PGM
DATA
18 Replace the SVPM control printed
circuit board.
Abnormality in an SVPM control cir-
cuit component is detected. (Pro-
gram ROM data is abnormal.)
9019 SPN_n_ : EX OFFSET
CURRENT U
19 Replace the SVPM unit. Abnormality in an SVPM component
is detected. (The initial value for the U
phase current detection circuit is ab-
normal.)
9020 SPN_n_ : EX OFFSET
CURRENT V
20 Replace the SVPM unit. Abnormality in an SVPM component
is detected. (The initial value of the V
phase current detection circuit is ab-
normal.)
9021 SPN_n_ : POS SENSOR
POLARITY ER-
ROR
21 Check and correct the parame-
ters.
(No. 4000#0, 4001#4)
The polarity parameter setting of the
position sensor is wrong.
9024 SPN_n_ : SERIAL
TRANSFER
ERROR
24 1 Place the CNC–to–spindle
cable away from the power
cable.
2 Replace the cable.
The CNC power is turned off (normal
power–off or broken cable).
An error is detected in communication
data transferred to the CNC.
9027 SPN_n_ : DISCONNECT
POS–CODER
27 Replace the cable. The spindle position coder (connector
JYA3) signal is abnormal.
