A.3 ALARM LIST (SERIAL SPINDLE)
When a serial spindle alarm occurs, the following number is displayed
on the CNC.
NOTE
* Note that the meanings of the SPM indications
differ depending on which LED, the red or yellow
LED, is on. When the red LED is on, the SPM
indicates a 2-digit alarm number. When the yellow
LED is on, the SPM indicates an error number that
designates a sequence problem (for example,
when a rotation command is entered with the
emergency stop state not released).
See "Error Codes (Serial Spindle)."

(*1)
Faulty location and remedy Description
SP9001 SSPA:01 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 motor
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.
SP9002 SSPA:02 EX
DEVIATION SPEED
02 1 Check and correct the
cutting conditions to
decrease the load.
2 Correct parameter No. 4082.
The motor speed cannot follow a
specified speed.
An excessive motor load torque is
detected.
The acceleration/deceleration time in
parameter No. 4082 is insufficient.
SP9003 SSPA:03 DC-LINK
FUSE IS BROKEN
03 1 Replace the SPM unit.
2 Check the motor insulation
status.
3 Replace the interface cable.
The PSM becomes ready (00 is
indicated), 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.
SP9004 SSPA:04 POWER
SUPPLY ERROR
04 Check the state of the input
power supply to the PSM.
The PSM found a missing power
supply phase. (PSM alarm 5)
SP9006 THERMAL SENSOR
DISCONNECT
06 1 Check and correct the
parameter.
2 Replace the feedback cable.
The temperature sensor of the motor
is disconnected.
