9-14
A.d00
Position Error
Pulse Overflow
( In servo ON
status, the
position error
pulses exceed
the overflow
level set in the
parameter
Pn520.)
Occurred when the
control power sup-
ply was turned
ON.
A SERVOPACK board fault occurred. Replace the SERVOPACK.
Occurred at the
servomotor high-
speed operation.
Faulty contact in the servomotor U, V, and W
wirings
Correct the servomotor wiring.
A SERVOPACK board fault occurred. Replace the SERVOPACK.
The servomotor
did not run with
position reference
input.
Incorrect wirings of the servomotor U, V, and W. Correct the servomotor wiring.
A SERVOPACK board fault occurred. Replace the SERVOPACK.
Normal move-
ment, but occurred
with a long dis-
tance reference
input.
Improper SERVOPACK gain adjustment Increase the speed loop gain (Pn100) and posi-
tion loop gain (Pn102).
The position reference pulse frequency is too
high.
Reduce slowly the position reference pulse fre-
quency.
Improper setting of the parameter Pn520 (Posi-
tion Error Pulse Overflow Alarm Level)
Set the parameter Pn520 to proper value.
The servomotor specifications do not meet the
load conditions such as torque and moment of
inertia.
Reconsider and correct the load and servomo-
tor capacity.
A.E02
I/F Alarm 2 Occurred when the
SynqNet commu-
nications was OFF.
This is not an alarm. Turn ON the SynqNet communication power
supply.
Occurred when the
module reset.
This is not an alarm.
−
Occurred during
operation.
A SERVOPACK board fault occurred. Replace the SERVOPACK.
A.E0A
FPGA WDC Er-
ror
Occurred when the
control power sup-
ply was turned
ON.
FPGA WDC malfunction. Replace the SERVOPACK.
A.E60
SynqNet Com-
munication Er-
ror
Occurred when the
control power sup-
ply was turned
ON.
SynqNet and SERVOPACK are not able to com-
municate due to network communication error.
Reset network, and check for noise generators.
A.F10
Power Line
Open Phase
(In the main
power supply
ON status, the
voltage stays low
for one second or
more at one of
the phases R, S,
and T.)
(Detected when
the main circuit
power supply
turns ON.)
Occurred when the
control power sup-
ply was turned
ON.
A SERVOPACK fault occurred. Replace the SERVOPACK.
Occurred when the
main circuit power
supply was turned
ON.
Incorrect three-phase power supply wiring Correct the power supply wiring.
Unbalanced three-phase power supply Balance the power supply by changing phases.
A SERVOPACK fault occurred. Replace the SERVOPACK.
Occurred when the
servomotor was
running.
Faulty contact in three-phase power supply wir-
ing
Correct the power supply wiring.
Unbalanced three-phase power supply Balance the power supply
A SERVOPACK fault occurred. Replace the SERVOPACK.
CPF00
Digital Opera-
tor Transmis-
sion Error 1
Occurred when the
power supply was
turned ON with
digital operator
connected or
when connecting
digital operator
with the power
supply ON.
The contact between digital operator and
SERVOPACK is faulty.
Insert securely the connector, or replace the
cable.
The external noise interference occurred to the
digital operator or cable is faulty.
Move cable away from noise sources.
CPF01
Digital Opera-
tor Transmis-
sion Error 2
A Digital operator fault occurred. Replace the digital operator.
A SERVOPACK fault occurred. Replace the SERVOPACK.
