Troubleshooting
40
Absolute encoder
system down error
Occurs when the power
supply is turned ON or
during operation.
The voltage supplied
to the absolute
encoder is low.
Set up the absolute
encoder.
Connect the battery
power supply.
41
Absolute encoder
counter overflow error Occurs during operation.
The multi-turn counter
of the absolute
encoder exceeds the
specified value.
Properly set the
Operation Switch
when Using Absolute
Encoder (Pn0B).
42
Absolute encoder
overspeed error
Occurs when the power
supply is turned ON.
The Servomotor
rotation speed
exceeds the specified
value when the battery
power supply is turned
ON.
The wiring is incorrect.
Lower the Servomotor
rotation speed and
supply power.
Check the wiring.
44
Absolute encoder
one-turn counter error
Occurs when the power
supply is turned ON.
The encoder is faulty. Replace the Servomo-
tor.
45
Absolute encoder
multi-turn counter er-
ror
Occurs when the power
supply is turned ON.
The absolute encoder
detected a counter er-
ror.
The incremental en-
coder detected a
counter error.
Replace the Servomo-
tor.
46 Encoder error 1
Occurs when the power
supply is turned ON
The Servomotor is
faulty.
Replace the Servo
Drive.
Replace the Servomo-
tor.
47
Absolute encoder
status error
Occurs when the power
supply is turned ON.
The Servomotor was
moving when the
power supply was
turned ON.
Do not let the Servo-
motor move when the
power supply is turned
ON.
48
Encoder ph
ase Z error Occurs during operation.
A phase-Z pulse from
the encoder was not
detected regularly.
Replace the Servomo-
tor.
49
Encoder PS signal
error
Occurs during operation.
A logic error was
detected in the PS
signal from the
encoder.
Replace the Servomo-
tor.
58 CPU error 1
Occurs when the power
supply is turned ON.
The Servo Drive is
faulty.
Replace the Servo
Drive.
60 CPU error 2
Occurs when the power
supply is turned ON.
The Servo Drive is
faulty.
Replace the Servo
Drive.
61 CPU error 3
Occurs when the power
supply is turned ON.
The Servo Drive is
faulty.
Replace the Servo
Drive.
62 CPU error 4
Occurs when the power
supply is turned ON.
The Servo Drive is
faulty.
Replace the Servo
Drive.
63 CPU error 5
Occurs when the power
supply is turned ON.
The Servo Drive is
faulty.
Replace the Servo
Drive.
65
Excessive analog
input 2
Occurs during operation.
The voltage input to
pin 16 is too high.
Reduce the input
voltage.
Change the value for
Pn71.
