Faulty location and remedy Description
9001 SPN_n_ : MOTOR
OVERHEAT
01 1 Check and correct the peripheral
temperature and load status.
2 If the cooling fan stops, replace it.
The thermostat embedded in the mo-
tor winding operated.
The internal temperature of the motor
exceeds the specified level.
The motor is used in excess of the
continuous rating, or the cooling
component is abnormal.
9002 SPN_n_ : EX SPEED ER-
ROR
02 1 Check and correct the cutting
conditions to decrease the load.
2 Correct parameter No. 4082.
The motor speed cannot follow a spe-
cified speed.
An excessive motor load torque is de-
tected.
The acceleration/deceleration time in
parameter No. 4082 is insufficient.
9003 SPN_n_ : FUSE ON DC
LINK BLOWN
03 1 Replace the SPM unit.
2 Check the motor insulation status.
3 Replace the interface cable.
The PSM becomes ready (00 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.)
The JX1A/JX1B connection cable is
abnormal.
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 5)
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.)
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 253 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 motor output current is abnor-
mally high.
A motor–specific parameter does not
match the motor model.
Poor motor insulation
