Faulty location and remedy Description
SP9036 SSPA:36
OVERFLOW
ERROR COUNTER
36 Check whether the position
gain value is too large, and
correct the value.
An error counter overflow occurred.
SP9037 SSPA:37 ILLEGAL
SETTING
VELOCITY
DETECTOR
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.
SP9041 SSPA:41 ILLEGAL
1REV SIGN OF
POSITION CODER
41 1 Check and correct the
parameter.
2 Replace the cable.
3 Re-adjust the BZ sensor
signal. Re-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
SP9042 SSPA:42 NO 1REV
SIGN OF POSITION
CODER
42 1 Replace the cable.
2 Re-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.
SP9043 SSPA:43
DISCONNECT
POSITION CODER
DEF. SPEED
43 Replace the cable. The differential speed position coder
signal (connector JY8) in SPM type 3
is abnormal.
SP9046 SSPA:46 ILLEGAL
1REV SIGN OF
SCREW CUT
46 1 Check and correct the
parameter.
2 Replace the cable.
3 Re-adjust the BZ sensor
signal.
An abnormality equivalent to alarm
41 was detected during thread
cutting operation.
SP9047 SSPA:47 ILLEGAL
SIGNAL OF
POSITION CODER
47 1 Replace the cable.
2 Re-adjust the BZ sensor
signal.
3 Correct the cable layout
(vicinity of the power line).
1 The A/B phase signal of the
spindle position coder (connector
JY4) is abnormal.
2 The A/B phase signal (connector
JY2) of the MZ or BZ sensor is
abnormal.
The relationship between the A/B
phase and 1-rotation signal is
incorrect (Pulse interval mismatch).
SP9049 SSPA:49 DEF.
SPEED IS OVER
VALUE
49 Check whether the calculated
differential speed value
exceeds the maximum motor
speed.
In differential speed mode, the speed
of the other spindle converted to the
speed of the local spindle has
exceeded the allowable limit (the
differential speed is calculated by
multiplying the speed of the other
spindle by the gear ratio).
SP9050 SSPA:50
SYNCRONOUS
VALUE IS OVER
SPEED
50 Check whether the calculated
value exceeds the maximum
motor speed.
In spindle synchronization, the speed
command calculation value
exceeded the allowable limit (the
motor speed is calculated by
multiplying the specified spindle
speed by the gear ratio).
