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.
