Message
9030 SPN_n_ : OVERCUR-
RENT POW
CIRCUIT
30 Check and correct the power supply
voltage.
Overcurrent is detected in PSM main
circuit input. (PSM alarm indication:
1)
Unbalanced power supply.
PSM selection error (The maximum
PSM output specification is exceed-
ed.)
9031 SPN_n_ : MOTOR LOCK
OR V–SIG LOS
31 1 Check and correct the load status.
2 Replace the motor sensor cable
(JY2 or JY5).
The motor cannot rotate at a speci-
fied speed. (A level not exceeding
the SST level for the rotation com-
mand has existed continuously.)
Abnormality in the speed detection
signal.
9032 SPN_n_ : RAM FAULT
SERIAL LSI
32 Replace the SPM control printed cir-
cuit board.
Abnormality in an SPM control circuit
component is detected. (The LSI de-
vice for serial transfer is abnormal.)
9033 SPN_n_ : SHORTAGE
POWER
CHARGE
33 1 Check and correct the power sup-
ply voltage.
2 Replace the PSM unit.
Charging of direct current power sup-
ply voltage in the power circuit sec-
tion is insufficient when the magnetic
contractor in the amplifier is turned on
(such as open phase and defective
charging resistor).
9034 SPN_n_ : PARAMETER
SETTING ER-
ROR
34 Correct a parameter value according
to the manual.
If the parameter number is unknown,
connect the spindle check board, and
check the indicated parameter.
Parameter data exceeding the allow-
able limit is set.
9035 SPN_n_ : EX SETTING
GEAR RATIO
35 Correct the value according to the pa-
rameter manual.
Gear ratio data exceeding the allow-
able limit is set.
9036 SPN_n_ : OVERFLOW
ERROR
COUNTER
36 Check whether the position gain val-
ue is too large, and correct the value.
An error counter overflow occurred.
9037 SPN_n_ : SPEED DE-
TECT PAR.
ERROR
37 Correct the value according to the pa-
rameter manual.
The setting of the parameter for the
number of pulses in the speed detec-
tor is incorrect.
9039 SPN_n_ : 1–ROT Cs
SIGNAL ER-
ROR
39 1 Adjust the 1–rotation signal in the
pre–amplifier.
2 Check the cable shield status.
3 Replace the cable.
An incorrect relationship between the
1–rotation signal and the number of
AB phase pulses was detected dur-
ing Cs contour control.
9040 SPN_n_ : NO 1–ROT Cs
SIGNAL DE-
TECT
40 1 Adjust the 1–rotation signal in the
pre–amplifier.
2 Check the cable shield status.
3 Replace the cable.
The 1–rotation signal is not gener-
ated during Cs contour control.
9041 SPN_n_ : 1–ROT POS–
CODER ER-
ROR
41 1 Check and correct the parameter.
2 Replace the cable.
3Re–adjust the BZ sensor signal.
1 The 1–rotation signal of the
spindle position coder (connector
JY4) is abnormal.
2 The 1–rotation signal (connector
JY2) of the MZ or BZ sensor is ab-
normal.
3 Parameter setting error
