Number Message
SPM
indication
(*1)
Faulty location and remedy Description
SP9007 SSPA:07 OVER
SPEED
07 Check for a sequence error.
(For example, check whether
spindle synchronization 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.)
SP9009 SSPA:09
OVERHEAT MAIN
CIRCUIT
09 1 Improve the heat sink
cooling status.
2 If the heat sink cooling fan
stops, replace the SPM
unit.
Abnormal temperature rise of the
power transistor radiator
SP9011 SSPA:11
OVERVOLT POWER
CIRCUIT
11 1 Check the selected PSM.
2 Check the input power
voltage and change in power
during motor deceleration.
If the voltage exceeds 253
VAC (for the 200-V system)
or 530 VAC (for the 400-V
system), improve the power
supply 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
exceeded.)
SP9012 SSPA:12
OVERCURRENT
POWER CIRCUIT
12 1 Check the motor insulation
status.
2 Check the spindle
parameters.
3 Replace the SPM unit.
The motor output current is
abnormally high.
A motor-specific parameter does not
match the motor model.
Poor motor insulation
SP9013 SSPA:13 CPU DATA
MEMORY FAULT
13 Replace the SPM control
printed circuit board.
Abnormality in an SPM control circuit
component is detected. (RAM within
the SPM is abnormal.)
SP9015 SSPA:15 SPINDLE
SWITCHING FAULT
15 1 Check and correct the
ladder sequence.
2 Replace the switching MC.
The switch sequence in spindle
switch/output switch operation is
abnormal.
The switching MC contact status
check signal and command do not
match.
SP9016 SSPA:16 RAM
ERROR
16 Replace the SPM control
printed circuit board.
Abnormality in an SPM control circuit
component is detected. (RAM for
external data is abnormal.)
SP9018 SSPA:18
SUMCHECK
ERROR PROGRAM
ROM
18 Replace the SPM control
printed circuit board.
Abnormality in an SPM control circuit
component is detected. (Program
ROM data is abnormal.)
SP9019 SSPA:19 EXCESS
OFFSET CURRENT
U
19 Replace the SPM unit. Abnormality in an SPM component is
detected. (The initial value for the U
phase current detection circuit is
abnormal.)
SP9020 SSPA:20 EXCESS
OFFSET CURRENT
V
20 Replace the SPM unit. Abnormality in an SPM component is
detected. (The initial value of the V
phase current detection circuit is
abnormal.)
