9003 SPN_n_ : FUSE ON DC
LINK BLOWN
03 1 Replace the SPM unit.
2 Check the motor insulation status.
The PSM becomes ready (0 is indi-
cated), but the DC link voltage is too
low in the SPM.
The fuse in the DC link section in the
SPM is blown. (The power device is
damaged or the motor is ground–
fault.)
9004 SPN_n_ : INPUT FUSE/
POWER
FAULT
04 Check the state of the input power
supply to the PSM.
The PSM found a missing power sup-
ply phase. (PSM alarm E)
9006 SPN_n_ : THERMAL
SENSOR DIS-
CONNECT
06 1 Check and correct the parameter.
2 Replace the feedback cable.
The temperature sensor of the motor
is disconnected.
9007 SPN_n_ : OVERSPEED 07 Check for a sequence error. (For ex-
ample, check whether spindle syn-
chronization 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 sta-
tus.
2 If the heat sink cooling fan stops,
replace the SPM unit.
Abnormal temperature rise of the
power transistor radiator
9011 SPN_n_ : OVERVOLT
POW CIRCUIT
11 1 Check the selected PSM.
2 Check the input power voltage
and change in power during motor
deceleration. If the voltage ex-
ceeds 264 VAC (for the 200–V
system) or 530 VAC (for the 400–V
system), improve the power sup-
ply impedance.
Overvoltage of the DC link section of
the PSM was detected. (PSM alarm
indication: 7)
PSM selection error. (The maximum
output specification of the PSM is ex-
ceeded.)
9012 SPN_n_ : OVERCUR-
RENT POW
CIRCUIT
12 1 Check the motor insulation status.
2 Check the spindle parameters.
3 Replace the SPM 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 SPM control printed cir-
cuit board.
An abnormality was detected in the
SPM control circuit.
(SPM internal RAM request)
9015 SPN_n_ : SP SWITCH
CONTROL
ALARM
15 1 Check and correct the ladder se-
quence.
2 Replace the switching MC.
The switch sequence in spindle
switch/output switch operation is ab-
normal.
The switching MC contact status
check signal and command do not
match.
9018 SPN_n_ : SUMCHECK
ERROR PGM
DATA
18 Replace the SPM control printed cir-
cuit board.
Abnormality in an SPM control circuit
component is detected. (Program
ROM data is abnormal.)
