DescriptionFaulty location and remedy
31 1 Check and correct the load status.
2 Replace the motor sensor cable (JY2 or JY5).
The motor cannot rotate at a specified speed. (A level
not exceeding the SST level for the rotation command
has existed continuously.)
Abnormality in the speed detection signal.
32 Replace the SPM control printed circuit board. Abnormality in an SPM control circuit component is de-
tected. (The LSI device for serial transfer is abnormal.)
33 1 Check and correct the power supply voltage.
2 Replace the PSM unit.
Charging of direct current power supply voltage in the
power circuit section is insufficient when the magnetic
contractor in the amplifier is turned on (such as open
phase and defective charging resistor).
34 Correct a parameter value according to the manual.
If the parameter number is unknown, connect the
spindle check board, and check the indicated parame-
ter.
Parameter data exceeding the allowable limit is set.
35 Correct the value according to the parameter manual. Gear ratio data exceeding the allowable limit is set.
36 Check whether the position gain value is too large, and
correct the value.
An error counter overflow occurred.
37 Correct the value according to the parameter manual. The setting of the parameter for the number of pulses in
the speed detector is incorrect.
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.
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 generated during Cs contour
control.
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 abnormal.
3 Parameter setting error
42 1 Replace the cable.
2Re–adjust the BZ sensor signal.
1 The 1–rotation signal of the spindle position coder
(connector JY4) is disconnected.
2 The 1–rotation signal (connector JY2) of the MZ or BZ
sensor is disconnected.
43 Replace the cable. The differential speed position coder signal (connector
JY8) in SPM type 3 is abnormal.
44 Replace the SPM control printed circuit board. Abnormality in an SPM control circuit component was
detected (A/D converter abnormality).
46 1 Check and correct the parameter.
2 Replace the cable.
3Re–adjust the BZ sensor signal.
An abnormality equivalent to alarm 41 was detected dur-
ing thread cutting operation.
